Little is known of the early years of Savery's life and no trace has been found that he served in the Army, so the title "Captain" is thought to refer to some mining appointment, probably in the West of England. He may have been involved in the Glorious Revolution of 1688, for later he was well known to William of Orange. From 1705 to 1714 he was Treasurer for Sick and Wounded Seamen, and in 1714 he was appointed Surveyor of the Water Works at Hampton Court, a post he held until his death the following year. He was interested in mechanical devices; amongst his early contrivances was a clock.

He was the most prolific inventor of his day, applying for seven patents, including one in 1649, for polishing plate glass which may have been used. His idea for 1697 for propelling ships with paddle-wheels driven by a capstan was a failure, although regarded highly by the King, and was published in his first book, Navigation Improved (1698). He tried to patent a new type of floating mill in 1707, and an idea in 1710 for baking sea coal or other fuel in an oven to make it clean and pure.

His most famous invention, however, was the one patented in 1698 "for raising water by the impellent force of fire" that Savery said would drain mines or low-lying land, raise water to supply towns or houses, and provide a source of water for turning mills through a water-wheel. Basically it consisted of a receiver which was first filled with steam and then cooled to create a vacuum by having water poured over the outside. The water to be pumped was drawn into the receiver from a lower sump, and then high-pressure steam was readmitted to force the water up a pipe to a higher level. It was demonstrated to the King and the Royal Society and achieved some success, for a few were installed in the London area and a manufactory set up at Salisbury Court in London. He published a book, The Miner's Friend, about his engine in 1702, but although he made considerable improvements, due to excessive fuel consumption and materials which could not withstand the steam pressures involved, no engines were installed in mines as Savery had hoped. His patent was extended in 1699 until 1733 so that it covered the atmospheric engine of Thomas Newcomen who was forced to join Savery and his other partners to construct this much more practical engine.

Soon after graduating from the Ecole des Mines at St-Etienne in 1910, Chevenard joined the Société de Commentry Fourchambault et Decazeville at their steelworks at Imphy, where he remained for the whole of his career. Imphy had for some years specialized in the production of nickel steels. From this venture emerged the first austenitic nickel-chromium steel, containing 6 per cent chromium and 22–4 per cent nickel and produced commercially in 1895. Most of the alloys required by Guillaume in his search for the low-expansion alloy Invar were made at Imphy. At the Imphy Research Laboratory, established in 1911, Chevenard conducted research into the development of specialized nickel-based alloys. His first success followed from an observation that some of the ferro-nickels were free from the low-temperature brittleness exhibited by conventional steels. To satisfy the technical requirements of Georges Claude, the French cryogenic pioneer, Chevenard was then able in 1912 to develop an alloy containing 55–60 per cent nickel, 1–3 per cent manganese and 0.2–0.4 per cent carbon. This was ductile down to −190°C, at which temperature carbon steel was very brittle.

By 1916 Elinvar, a nickel-iron-chromium alloy with an elastic modulus that did not vary appreciably with changes in ambient temperature, had been identified. This found extensive use in horology and instrument manufacture, and even for the production of high-quality tuning forks. Another very popular alloy was Platinite, which had the same coefficient of thermal expansion as platinum and soda glass. It was used in considerable quantities by incandescent-lamp manufacturers for lead-in wires. Other materials developed by Chevenard at this stage to satisfy the requirements of the electrical industry included resistance alloys, base-metal thermocouple combinations, magnetically soft high-permeability alloys, and nickel-aluminium permanent magnet steels of very high coercivity which greatly improved the power and reliability of car magnetos. Thermostatic bimetals of all varieties soon became an important branch of manufacture at Imphy.

During the remainder of his career at Imphy, Chevenard brilliantly elaborated the work on nickel-chromium-tungsten alloys to make stronger pressure vessels for the Haber and other chemical processes. Another famous alloy that he developed, ATV, contained 35 per cent nickel and 11 per cent chromium and was free from the problem of stress-induced cracking in steam that had hitherto inhibited the development of high-power steam turbines. Between 1912 and 1917, Chevenard recognized the harmful effects of traces of carbon on this type of alloy, and in the immediate postwar years he found efficient methods of scavenging the residual carbon by controlled additions of reactive metals. This led to the development of a range of stabilized austenitic stainless steels which were free from the problems of intercrystalline corrosion and weld decay that then caused so much difficulty to the manufacturers of chemical plant.

Chevenard soon concluded that only the nickel-chromium system could provide a satisfactory basis for the subsequent development of high-temperature alloys. The first published reference to the strengthening of such materials by additions of aluminium and/or titanium occurs in his UK patent of 1929. This strengthening approach was adopted in the later wartime development in Britain of the Nimonic series of alloys, all of which depended for their high-temperature strength upon the precipitated compound Ni3Al.

In 1936 he was studying the effect of what is now known as "thermal fatigue", which contributes to the eventual failure of both gas and steam turbines. He then published details of equipment for assessing the susceptibility of nickel-chromium alloys to this type of breakdown by a process of repeated quenching. Around this time he began to make systematic use of the thermo-gravimetrie balance for high-temperature oxidation studies.

Jesse Ramsden was the son of an innkeeper but received a good general education: after attending the free school at Halifax, he was sent at the age of 12 to his uncle for further study, particularly in mathematics. At the age of 16 he was apprenticed to a cloth-worker in Halifax and on completion of the apprenticeship in 1755 he moved to London to work as a clerk in a cloth warehouse. In 1758 he became an apprentice in the workshop of a London mathematical instrument-maker named Burton. He quickly gained the skill, particularly in engraving, and by 1762 he was able to set up on his own account. He married in 1765 or 1766 the youngest daughter of the optician John Dollond FRS (1706– 61) and received a share of Dollond's patent for making achromatic lenses.

Ramsden's experience and reputation increased rapidly and he was generally regarded as the leading instrument-maker of his time. He opened a shop in the Haymarket and transferred to Piccadilly in 1775. His staff increased to about sixty workers and apprentices, and by 1789 he had constructed nearly 1,000 sextants as well as theodolites, micrometers, balances, barometers, quadrants and other instruments.

One of Ramsden's most important contributions to precision measurement was his development of machines for obtaining accurate division of angular and linear scales. For this work he received a premium from the Commissioners of the Board of Longitude, who published his descriptions of the machines. For the trigonometrical survey of Great Britain, initiated by General William Roy FRS (1726–90) and continued by the Board of Ordnance, Ramsden supplied a 3 ft (91 cm) theodolite and steel measuring chains, and was also engaged to check the glass tubes used to measure the fundamental base line.

   1) There Are Ideas That Have Their Own True and Immutable Nature

   And what I believe to be more important here is that I find in myself an infinity of ideas of certain things which cannot be assumed to be pure nothingness, even though they may have perhaps no existence outside of my thought. These things are not figments of my imagination, even though it is within my power to think of them or not to think of them; on the contrary, they have their own true and immutable natures. Thus, for example, when I imagine a triangle, even though there may perhaps be no such figure anywhere in the world outside of my thought, nor ever have been, nevertheless the figure cannot help having a certain determinate nature... or essence, which is immutable and eternal, which I have not invented and which does not in any way depend upon my mind. (Descartes, 1951, p. 61)

   2) Examine What Is within Our Reach

   Let us console ourselves for not knowing the possible connections between a spider and the rings of Saturn, and continue to examine what is within our reach. (Voltaire, 1961, p. 144)

   3) Modern Philosophy Starts with the Cartesian Catastrophe

   As modern physics started with the Newtonian revolution, so modern philosophy starts with what one might call the Cartesian Catastrophe. The catastrophe consisted in the splitting up of the world into the realms of matter and mind, and the identification of "mind" with conscious thinking. The result of this identification was the shallow rationalism of l'esprit Cartesien, and an impoverishment of psychology which it took three centuries to remedy even in part. (Koestler, 1964, p. 148)

   4) The Rightful Claims of Philosophy

   It has been made of late a reproach against natural philosophy that it has struck out on a path of its own, and has separated itself more and more widely from the other sciences which are united by common philological and historical studies. The opposition has, in fact, been long apparent, and seems to me to have grown up mainly under the influence of the Hegelian philosophy, or, at any rate, to have been brought out into more distinct relief by that philosophy.... The sole object of Kant's "Critical Philosophy" was to test the sources and the authority of our knowledge, and to fix a definite scope and standard for the researches of philosophy, as compared with other sciences.... [But Hegel's] "Philosophy of Identity" was bolder. It started with the hypothesis that not only spiritual phenomena, but even the actual world-nature, that is, and man-were the result of an act of thought on the part of a creative mind, similar, it was supposed, in kind to the human mind.... The philosophers accused the scientific men of narrowness; the scientific men retorted that the philosophers were crazy. And so it came about that men of science began to lay some stress on the banishment of all philosophic influences from their work; while some of them, including men of the greatest acuteness, went so far as to condemn philosophy altogether, not merely as useless, but as mischievous dreaming. Thus, it must be confessed, not only were the illegitimate pretensions of the Hegelian system to subordinate to itself all other studies rejected, but no regard was paid to the rightful claims of philosophy, that is, the criticism of the sources of cognition, and the definition of the functions of the intellect. (Helmholz, quoted in Dampier, 1966, pp. 291-292)

   5) The Philosophy of Philosophy

   Philosophy remains true to its classical tradition by renouncing it. (Habermas, 1972, p. 317)

   6) Philosophy Is a Field Which Has Certain Central Questions

   I have not attempted... to put forward any grand view of the nature of philosophy; nor do I have any such grand view to put forth if I would. It will be obvious that I do not agree with those who see philosophy as the history of "howlers" and progress in philosophy as the debunking of howlers. It will also be obvious that I do not agree with those who see philosophy as the enterprise of putting forward a priori truths about the world.... I see philosophy as a field which has certain central questions, for example, the relation between thought and reality.... It seems obvious that in dealing with these questions philosophers have formulated rival research programs, that they have put forward general hypotheses, and that philosophers within each major research program have modified their hypotheses by trial and error, even if they sometimes refuse to admit that that is what they are doing. To that extent philosophy is a "science." To argue about whether philosophy is a science in any more serious sense seems to me to be hardly a useful occupation.... It does not seem to me important to decide whether science is philosophy or philosophy is science as long as one has a conception of both that makes both essential to a responsible view of the world and of man's place in it. (Putnam, 1975, p. xvii)

   7) The Central Task of Philosophy

   What can philosophy contribute to solving the problem of the relation [of] mind to body? Twenty years ago, many English-speaking philosophers would have answered: "Nothing beyond an analysis of the various mental concepts." If we seek knowledge of things, they thought, it is to science that we must turn. Philosophy can only cast light upon our concepts of those things.

   This retreat from things to concepts was not undertaken lightly. Ever since the seventeenth century, the great intellectual fact of our culture has been the incredible expansion of knowledge both in the natural and in the rational sciences (mathematics, logic).

   The success of science created a crisis in philosophy. What was there for philosophy to do? Hume had already perceived the problem in some degree, and so surely did Kant, but it was not until the twentieth century, with the Vienna Circle and with Wittgenstein, that the difficulty began to weigh heavily. Wittgenstein took the view that philosophy could do no more than strive to undo the intellectual knots it itself had tied, so achieving intellectual release, and even a certain illumination, but no knowledge. A little later, and more optimistically, Ryle saw a positive, if reduced role, for philosophy in mapping the "logical geography" of our concepts: how they stood to each other and how they were to be analyzed....

   Since that time, however, philosophers in the "analytic" tradition have swung back from Wittgensteinian and even Rylean pessimism to a more traditional conception of the proper role and tasks of philosophy. Many analytic philosophers now would accept the view that the central task of philosophy is to give an account, or at least play a part in giving an account, of the most general nature of things and of man. (Armstrong, 1990, pp. 37-38)

   8) Philosophy's Evolving Engagement with Artificial Intelligence and Cognitive Science

   In the beginning, the nature of philosophy's engagement with artificial intelligence and cognitive science was clear enough. The new sciences of the mind were to provide the long-awaited vindication of the most potent dreams of naturalism and materialism. Mind would at last be located firmly within the natural order. We would see in detail how the most perplexing features of the mental realm could be supported by the operations of solely physical laws upon solely physical stuff. Mental causation (the power of, e.g., a belief to cause an action) would emerge as just another species of physical causation. Reasoning would be understood as a kind of automated theorem proving. And the key to both was to be the depiction of the brain as the implementation of multiple higher level programs whose task was to manipulate and transform symbols or representations: inner items with one foot in the physical (they were realized as brain states) and one in the mental (they were bearers of contents, and their physical gymnastics were cleverly designed to respect semantic relationships such as truth preservation). (A. Clark, 1996, p. 1)

   9) The Enduring Value of Philosophy

   Socrates of Athens famously declared that "the unexamined life is not worth living," and his motto aptly explains the impulse to philosophize. Taking nothing for granted, philosophy probes and questions the fundamental presuppositions of every area of human inquiry.... [P]art of the job of the philosopher is to keep at a certain critical distance from current doctrines, whether in the sciences or the arts, and to examine instead how the various elements in our world-view clash, or fit together. Some philosophers have tried to incorporate the results of these inquiries into a grand synoptic view of the nature of reality and our human relationship to it. Others have mistrusted system-building, and seen their primary role as one of clarifications, or the removal of obstacles along the road to truth. But all have shared the Socratic vision of using the human intellect to challenge comfortable preconceptions, insisting that every aspect of human theory and practice be subjected to continuing critical scrutiny....

   Philosophy is, of course, part of a continuing tradition, and there is much to be gained from seeing how that tradition originated and developed. But the principal object of studying the materials in this book is not to pay homage to past genius, but to enrich one's understanding of central problems that are as pressing today as they have always been-problems about knowledge, truth and reality, the nature of the mind, the basis of right action, and the best way to live. These questions help to mark out the territory of philosophy as an academic discipline, but in a wider sense they define the human predicament itself; they will surely continue to be with us for as long as humanity endures. (Cottingham, 1996, pp. xxi-xxii)

    10) The Distinction between Dionysian Man and Apollonian Man, between Art and Creativity and Reason and Self- Control

   In his study of ancient Greek culture, The Birth of Tragedy, Nietzsche drew what would become a famous distinction, between the Dionysian spirit, the untamed spirit of art and creativity, and the Apollonian, that of reason and self-control. The story of Greek civilization, and all civilizations, Nietzsche implied, was the gradual victory of Apollonian man, with his desire for control over nature and himself, over Dionysian man, who survives only in myth, poetry, music, and drama. Socrates and Plato had attacked the illusions of art as unreal, and had overturned the delicate cultural balance by valuing only man's critical, rational, and controlling consciousness while denigrating his vital life instincts as irrational and base. The result of this division is "Alexandrian man," the civilized and accomplished Greek citizen of the later ancient world, who is "equipped with the greatest forces of knowledge" but in whom the wellsprings of creativity have dried up. (Herman, 1997, pp. 95-96)

(1924-)

   Lawyer, staunch oppositionist to the Estado Novo, a founder of Portugal's Socialist Party (PS), key leader of post-1974 democratic Portugal, and twice-elected president of the republic (1986-91; 1991-96). Mário Soares was born on 7 December 1924, in Lisbon, the son of an educator and former cabinet officer of the ill-fated First Republic. An outstanding student, Soares received a degree in history and philosophy from the University of Lisbon (1951) and his law degree from the same institution (1957). A teacher and a lawyer, the young Soares soon became active in various organizations that opposed the Estado Novo, starting in his student days and continuing into his association with the PS. He worked with the organizations of several oppositionist candidates for the presidency of the republic in 1949 and 1958 and, as a lawyer, defended a number of political figures against government prosecution in court. Soares was the family attorney for the family of General Humberto Delgado, murdered on the Spanish frontier by the regime's political police in 1965. Soares was signatory and editor of the "Program for the Democratization of the Republic" in 1961, and, in 1968, he was deported by the regime to São Tomé, one of Portugal's African colonies.

   In 1969, following the brief liberalization under the new prime minister Marcello Caetano, Soares returned from exile in Africa and participated as a member of the opposition in general elections for the National Assembly. Although harassed by the PIDE, he was courageous in attacking the government and its colonial policies in Africa. After the rigged election results were known, and no oppositionist deputy won a seat despite the Caetano "opening," Soares left for exile in France. From 1969 to 1974, he resided in France, consulted with other political exiles, and taught at a university. In 1973, at a meeting in West Germany, Soares participated in the (re)founding of the (Portuguese) Socialist Party.

   The exciting, unexpected news of the Revolution of 25 April 1974 reached Soares in France, and soon he was aboard a train bound for Lisbon, where he was to play a major role in the difficult period of revolutionary politics (1974-75). During a most critical phase, the "hot summer" of 1975, when a civil war seemed in the offing, Soares's efforts to steer Portugal away from a communist dictatorship and sustained civil strife were courageous and effective. He found allies in the moderate military and large sectors of the population. After the abortive leftist coup of 25 November 1975, Soares played an equally vital role in assisting the stabilization of a pluralist democracy.

   Prime minister on several occasions during the era of postrevolu-tionary adjustment (1976-85), Soares continued his role as the respected leader of the PS. Following 11 hectic years of the Lusitanian political hurly-burly, Soares was eager for a change and some rest. Prepared to give up leadership of the factious PS and become a senior statesman in the new Portugal, Mário Soares ran for the presidency of the republic. After serving twice as elected president of the republic, he established the Mário Soares Foundation, Lisbon, and was elected to the European Parliament.

Charles Babbage was the son of a banker, Benjamin Babbage, and was a sickly child who had a rather haphazard education at private schools near Exeter and later at Enfield. Even as a child, he was inordinately fond of algebra, which he taught himself. He was conversant with several advanced mathematical texts, so by the time he entered Trinity College, Cambridge, in 1811, he was ahead of his tutors. In his third year he moved to Peterhouse, whence he graduated in 1814, taking his MA in 1817. He first contributed to the Philosophical Transactions of the Royal Society in 1815, and was elected a fellow of that body in 1816. He was one of the founders of the Astronomical Society in 1820 and served in high office in it.

While he was still at Cambridge, in 1812, he had the first idea of calculating numerical tables by machinery. This was his first difference engine, which worked on the principle of repeatedly adding a common difference. He built a small model of an engine working on this principle between 1820 and 1822, and in July of the latter year he read an enthusiastically received note about it to the Astronomical Society. The following year he was awarded the Society's first gold medal. He submitted details of his invention to Sir Humphry Davy, President of the Royal Society; the Society reported favourably and the Government became interested, and following a meeting with the Chancellor of the Exchequer Babbage was awarded a grant of £1,500. Work proceeded and was carried on for four years under the direction of Joseph Clement.

In 1827 Babbage went abroad for a year on medical advice. There he studied foreign workshops and factories, and in 1832 he published his observations in On the Economy of Machinery and Manufactures. While abroad, he received the news that he had been appointed Lucasian Professor of Mathematics at Cambridge University. He held the Chair until 1839, although he neither resided in College nor gave any lectures. For this he was paid between £80 and £90 a year! Differences arose between Babbage and Clement. Manufacture was moved from Clement's works in Lambeth, London, to new, fireproof buildings specially erected by the Government near Babbage's house in Dorset Square, London. Clement made a large claim for compensation and, when it was refused, withdrew his workers as well as all the special tools he had made up for the job. No work was possible for the next fifteen months, during which Babbage conceived the idea of his "analytical engine". He approached the Government with this, but it was not until eight years later, in 1842, that he received the reply that the expense was considered too great for further backing and that the Government was abandoning the project. This was in spite of the demonstration and perfectly satisfactory operation of a small section of the analytical engine at the International Exhibition of 1862. It is said that the demands made on manufacture in the production of his engines had an appreciable influence in improving the standard of machine tools, whilst similar benefits accrued from his development of a system of notation for the movements of machine elements. His opposition to street organ-grinders was a notable eccentricity; he estimated that a quarter of his mental effort was wasted by the effect of noise on his concentration.

De Forest was born into the family of a Congregational minister that moved to Alabama in 1879 when the father became President of a college for African-Americans; this was a position that led to the family's social ostracism by the white community. By the time he was 13 years old, De Forest was already a keen mechanical inventor, and in 1893, rejecting his father's plan for him to become a clergyman, he entered the Sheffield Scientific School of Yale University. Following his first degree, he went on to study the propagation of electromagnetic waves, gaining a PhD in physics in 1899 for his thesis on the "Reflection of Hertzian Waves from the Ends of Parallel Wires", probably the first US thesis in the field of radio.

He then joined the Western Electric Company in Chicago where he helped develop the infant technology of wireless, working his way up from a modest post in the production area to a position in the experimental laboratory. There, working alone after normal working hours, he developed a detector of electromagnetic waves based on an electrolytic device similar to that already invented by Fleming in England. Recognizing his talents, a number of financial backers enabled him to set up his own business in 1902 under the name of De Forest Wireless Telegraphy Company; he was soon demonstrating wireless telegraphy to interested parties and entering into competition with the American Marconi Company.

Despite the failure of this company because of fraud by his partners, he continued his experiments; in 1907, by adding a third electrode, a wire mesh, between the anode and cathode of the thermionic diode invented by Fleming in 1904, he was able to produce the amplifying device now known as the triode valve and achieve a sensitivity of radio-signal reception much greater than possible with the passive carborundum and electrolytic detectors hitherto available. Patented under the name Audion, this new vacuum device was soon successfully used for experimental broadcasts of music and speech in New York and Paris. The invention of the Audion has been described as the beginning of the electronic era. Although much development work was required before its full potential was realized, the Audion opened the way to progress in all areas of sound transmission, recording and reproduction. The patent was challenged by Fleming and it was not until 1943 that De Forest's claim was finally recognized.

Overcoming the near failure of his new company, the De Forest Radio Telephone Company, as well as unsuccessful charges of fraudulent promotion of the Audion, he continued to exploit the potential of his invention. By 1912 he had used transformer-coupling of several Audion stages to achieve high gain at radio frequencies, making long-distance communication a practical proposition, and had applied positive feedback from the Audion output anode to its input grid to realize a stable transmitter oscillator and modulator. These successes led to prolonged patent litigation with Edwin Armstrong and others, and he eventually sold the manufacturing rights, in retrospect often for a pittance.

During the early 1920s De Forest began a fruitful association with T.W.Case, who for around ten years had been working to perfect a moving-picture sound system. De Forest claimed to have had an interest in sound films as early as 1900, and Case now began to supply him with photoelectric cells and primitive sound cameras. He eventually devised a variable-density sound-on-film system utilizing a glow-discharge modulator, the Photion. By 1926 De Forest's Phonofilm had been successfully demonstrated in over fifty theatres and this system became the basis of Movietone. Though his ideas were on the right lines, the technology was insufficiently developed and it was left to others to produce a system acceptable to the film industry. However, De Forest had played a key role in transforming the nature of the film industry; within a space of five years the production of silent films had all but ceased.

In the following decade De Forest applied the Audion to the development of medical diathermy. Finally, after spending most of his working life as an independent inventor and entrepreneur, he worked for a time during the Second World War at the Bell Telephone Laboratories on military applications of electronics.

Very little is known about the life of James Fox, but according to Samuel Smiles (1863) he was as a young man a butler in the service of the Reverend Thomas Gisborne of Foxhall Lodge, Staffordshire. His mechanical abilities were evident from his spare-time activities in the handling of tools and so impressed his employer that he supplied the capital to enable Fox to set up a business in Derby for the manufacture of machinery for the textile and lacemaking industries. To construct this machinery, Fox had to build his own machine tools and later, in the early nineteenth century, made them for sale, some being exported to France, Germany and Poland. He was renowned for his lathes, some of which were quite large; one built in 1830 has been preserved and is 22 ft (6.7 m) long with a swing of 27 in. (69 cm). He was responsible for many improve-ments in the design of the lathe and he also built some of the earliest planing machines (the first, it has been claimed, as early as 1814) and a gear-cutting machine, although this was apparently for cutting wooden patterns for cast gears. The business was continued by his sons Joseph and James (who died in 1859 aged 69) and into the 1860s by the sons of Joseph.

Leonardo was the illegitimate son of a Florentine lawyer. His first sixteen years were spent with the lawyer's family in the rural surroundings of Vinci, which aroused in him a lifelong love of nature and an insatiable curiosity in it. He received little formal education but extended his knowledge through private reading. That gave him only a smattering of Latin, a deficiency that was to be a hindrance throughout his active life. At sixteen he was apprenticed in the studio of Andrea del Verrochio in Florence, where he received a training not only in art but in a wide variety of crafts and technical arts.

In 1482 Leonardo went to Milan, where he sought and obtained employment with Ludovico Sforza, later Duke of Milan, partly to sculpt a massive equestrian statue of Ludovico but the work never progressed beyond the full-scale model stage. He did, however, complete the painting which became known as the Virgin of the Rocks and in 1497 his greatest artistic achievement, The Last Supper, commissioned jointly by Ludovico and the friars of Santa Maria della Grazie and painted on the wall of the monastery's refectory. Leonardo was responsible for the court pageants and also devised a system of irrigation to supply water to the plains of Lombardy. In 1499 the French army entered Milan and deposed Leonardo's employer. Leonardo departed and, after a brief visit to Mantua, returned to Florence, where for a time he was employed as architect and engineer to Cesare Borgia, Duke of Romagna. Around 1504 he completed another celebrated work, the Mona Lisa.

In 1506 Leonardo began his second sojourn in Milan, this time in the service of King Louis XII of France, who appointed him "painter and engineer". In 1513 Leonardo left for Rome in the company of his pupil Francesco Melzi, but his time there was unproductive and he found himself out of touch with the younger artists active there, Michelangelo above all. In 1516 he accepted with relief an invitation from King François I of France to reside at the small château of St Cloux in the royal domain of Amboise. With the pension granted by François, Leonardo lived out his remaining years in tranquility at St Cloux.

Leonardo's career can hardly be regarded as a success or worthy of such a towering genius. For centuries he was known only for the handful of artistic works that he managed to complete and have survived more or less intact. His main activity remained hidden until the nineteenth and twentieth centuries, during which the contents of his notebooks were gradually revealed. It became evident that Leonardo was one of the greatest scientific investigators and inventors in the history of civilization. Throughout his working life he extended a searching curiosity over an extraordinarily wide range of subjects. The notes show careful investigation of questions of mechanical and civil engineering, such as power transmission by means of pulleys and also a form of chain belting. The notebooks record many devices, such as machines for grinding and polishing lenses, a lathe operated by treadle-crank, a rolling mill with conical rollers and a spinning machine with pinion and yard divider. Leonardo made an exhaustive study of the flight of birds, with a view to designing a flying machine, which obsessed him for many years.

Leonardo recorded his observations and conclusions, together with many ingenious inventions, on thousands of pages of manuscript notes, sketches and drawings. There are occasional indications that he had in mind the publication of portions of the notes in a coherent form, but he never diverted his energy into putting them in order; instead, he went on making notes. As a result, Leonardo's impact on the development of science and technology was virtually nil. Even if his notebooks had been copied and circulated, there were daunting impediments to their understanding. Leonardo was left-handed and wrote in mirror-writing: that is, in reverse from right to left. He also used his own abbreviations and no punctuation.

At his death Leonardo bequeathed his entire output of notes to his friend and companion Francesco Melzi, who kept them safe until his own death in 1570. Melzi left the collection in turn to his son Orazio, whose lack of interest in the arts and sciences resulted in a sad period of dispersal which endangered their survival, but in 1636 the bulk of them, in thirteen volumes, were assembled and donated to the Ambrosian Library in Milan. These include a large volume of notes and drawings compiled from the various portions of the notebooks and is now known as the Codex Atlanticus. There they stayed, forgotten and ignored, until 1796, when Napoleon's marauding army overran Italy and art and literary works, including the thirteen volumes of Leonardo's notebooks, were pillaged and taken to Paris. After the war in 1815, the French government agreed to return them but only the Codex Atlanticus found its way back to Milan; the rest remained in Paris. The appendix to one notebook, dealing with the flight of birds, was later regarded as of sufficient importance to stand on its own. Four small collections reached Britain at various times during the seventeenth and eighteenth centuries; of these, the volume in the Royal Collection at Windsor Castle is notable for its magnificent series of anatomical drawings. Other collections include the Codex Leicester and Codex Arundel in the British Museum in London, and the Madrid Codices in Spain.

Towards the end of the nineteenth century, Leonardo's true stature as scientist, engineer and inventor began to emerge, particularly with the publication of transcriptions and translations of his notebooks. The volumes in Paris appeared in 1881–97 and the Codex Atlanticus was published in Milan between 1894 and 1904.

He graduated from The Queen's College with a BA in 1915 and an MA in 1918. He was an instructor and lecturer in the Royal Navy in 1915–19. He became an administrative officer with the Board of Education until 1938, and continued his work in the British Civil Service in the Ministry of Transport until 1949. From 1924 to 1938 he was Technical Adviser, and from 1953 Technical Editor, with Gramophone, a publication catering for the record-and equipment-buying public. He brought a mathematical mind to the problems of gramophone reproduction and solved the geometrical problem of obtaining a reasonable approximation to tangential tracking across the surface of a record even though the soundbox (or pick-up) is carried by a pivoted arm. Later he tackled the problem of horns, determining that a modified exponential horn, even with a bent axis, would give optimal reproduction by a purely acoustic system. This development was used commercially during the 1930s. Wilson was for a time a member of the School Broadcasting Council and developed methods for improving subjective listening tests for evaluation of audio equipment. He was also deeply involved in the long-playing record system used for Talking Books for the Blind. He had a life-long interest in spiritualist matters and was President of the Spiritualist National Union from 1950 to 1953 and Chairman of the Psychic Press from 1951.

   Portugal is a small Western European nation with a large, distinctive past replete with both triumph and tragedy. One of the continent's oldest nation-states, Portugal has frontiers that are essentially unchanged since the late 14th century. The country's unique character and 850-year history as an independent state present several curious paradoxes. As of 1974, when much of the remainder of the Portuguese overseas empire was decolonized, Portuguese society appeared to be the most ethnically homogeneous of the two Iberian states and of much of Europe. Yet, Portuguese society had received, over the course of 2,000 years, infusions of other ethnic groups in invasions and immigration: Phoenicians, Greeks, Celts, Romans, Suevi, Visigoths, Muslims (Arab and Berber), Jews, Italians, Flemings, Burgundian French, black Africans, and Asians. Indeed, Portugal has been a crossroads, despite its relative isolation in the western corner of the Iberian Peninsula, between the West and North Africa, Tropical Africa, and Asia and America. Since 1974, Portugal's society has become less homogeneous, as there has been significant immigration of former subjects from its erstwhile overseas empire.

   Other paradoxes should be noted as well. Although Portugal is sometimes confused with Spain or things Spanish, its very national independence and national culture depend on being different from Spain and Spaniards. Today, Portugal's independence may be taken for granted. Since 1140, except for 1580-1640 when it was ruled by Philippine Spain, Portugal has been a sovereign state. Nevertheless, a recurring theme of the nation's history is cycles of anxiety and despair that its freedom as a nation is at risk. There is a paradox, too, about Portugal's overseas empire(s), which lasted half a millennium (1415-1975): after 1822, when Brazil achieved independence from Portugal, most of the Portuguese who emigrated overseas never set foot in their overseas empire, but preferred to immigrate to Brazil or to other countries in North or South America or Europe, where established Portuguese overseas communities existed.

   Portugal was a world power during the period 1415-1550, the era of the Discoveries, expansion, and early empire, and since then the Portuguese have experienced periods of decline, decadence, and rejuvenation. Despite the fact that Portugal slipped to the rank of a third- or fourth-rate power after 1580, it and its people can claim rightfully an unusual number of "firsts" or distinctions that assure their place both in world and Western history. These distinctions should be kept in mind while acknowledging that, for more than 400 years, Portugal has generally lagged behind the rest of Western Europe, although not Southern Europe, in social and economic developments and has remained behind even its only neighbor and sometime nemesis, Spain.

   Portugal's pioneering role in the Discoveries and exploration era of the 15th and 16th centuries is well known. Often noted, too, is the Portuguese role in the art and science of maritime navigation through the efforts of early navigators, mapmakers, seamen, and fishermen. What are often forgotten are the country's slender base of resources, its small population largely of rural peasants, and, until recently, its occupation of only 16 percent of the Iberian Peninsula. As of 1139—10, when Portugal emerged first as an independent monarchy, and eventually a sovereign nation-state, England and France had not achieved this status. The Portuguese were the first in the Iberian Peninsula to expel the Muslim invaders from their portion of the peninsula, achieving this by 1250, more than 200 years before Castile managed to do the same (1492).

   Other distinctions may be noted. Portugal conquered the first overseas empire beyond the Mediterranean in the early modern era and established the first plantation system based on slave labor. Portugal's empire was the first to be colonized and the last to be decolonized in the 20th century. With so much of its scattered, seaborne empire dependent upon the safety and seaworthiness of shipping, Portugal was a pioneer in initiating marine insurance, a practice that is taken for granted today. During the time of Pombaline Portugal (1750-77), Portugal was the first state to organize and hold an industrial trade fair. In distinctive political and governmental developments, Portugal's record is more mixed, and this fact suggests that maintaining a government with a functioning rule of law and a pluralist, representative democracy has not been an easy matter in a country that for so long has been one of the poorest and least educated in the West. Portugal's First Republic (1910-26), only the third republic in a largely monarchist Europe (after France and Switzerland), was Western Europe's most unstable parliamentary system in the 20th century. Finally, the authoritarian Estado Novo or "New State" (1926-74) was the longest surviving authoritarian system in modern Western Europe. When Portugal departed from its overseas empire in 1974-75, the descendants, in effect, of Prince Henry the Navigator were leaving the West's oldest empire.

   Portugal's individuality is based mainly on its long history of distinc-tiveness, its intense determination to use any means — alliance, diplomacy, defense, trade, or empire—to be a sovereign state, independent of Spain, and on its national pride in the Portuguese language. Another master factor in Portuguese affairs deserves mention. The country's politics and government have been influenced not only by intellectual currents from the Atlantic but also through Spain from Europe, which brought new political ideas and institutions and novel technologies. Given the weight of empire in Portugal's past, it is not surprising that public affairs have been hostage to a degree to what happened in her overseas empire. Most important have been domestic responses to imperial affairs during both imperial and internal crises since 1415, which have continued to the mid-1970s and beyond. One of the most important themes of Portuguese history, and one oddly neglected by not a few histories, is that every major political crisis and fundamental change in the system—in other words, revolution—since 1415 has been intimately connected with a related imperial crisis. The respective dates of these historical crises are: 1437, 1495, 1578-80, 1640, 1820-22, 1890, 1910, 1926-30, 1961, and 1974. The reader will find greater detail on each crisis in historical context in the history section of this introduction and in relevant entries.

   LAND AND PEOPLE

   The Republic of Portugal is located on the western edge of the Iberian Peninsula. A major geographical dividing line is the Tagus River: Portugal north of it has an Atlantic orientation; the country to the south of it has a Mediterranean orientation. There is little physical evidence that Portugal is clearly geographically distinct from Spain, and there is no major natural barrier between the two countries along more than 1,214 kilometers (755 miles) of the Luso-Spanish frontier. In climate, Portugal has a number of microclimates similar to the microclimates of Galicia, Estremadura, and Andalusia in neighboring Spain. North of the Tagus, in general, there is an Atlantic-type climate with higher rainfall, cold winters, and some snow in the mountainous areas. South of the Tagus is a more Mediterranean climate, with hot, dry, often rainless summers and cool, wet winters. Lisbon, the capital, which has a fifth of the country's population living in its region, has an average annual mean temperature about 16° C (60° F).

   For a small country with an area of 92,345 square kilometers (35,580 square miles, including the Atlantic archipelagos of the Azores and the Madeiras), which is about the size of the state of Indiana in the United States, Portugal has a remarkable diversity of regional topography and scenery. In some respects, Portugal resembles an island within the peninsula, embodying a unique fusion of European and non-European cultures, akin to Spain yet apart. Its geography is a study in contrasts, from the flat, sandy coastal plain, in some places unusually wide for Europe, to the mountainous Beira districts or provinces north of the Tagus, to the snow-capped mountain range of the Estrela, with its unique ski area, to the rocky, barren, remote Trás-os-Montes district bordering Spain. There are extensive forests in central and northern Portugal that contrast with the flat, almost Kansas-like plains of the wheat belt in the Alentejo district. There is also the unique Algarve district, isolated somewhat from the Alentejo district by a mountain range, with a microclimate, topography, and vegetation that resemble closely those of North Africa.

   Although Portugal is small, just 563 kilometers (337 miles) long and from 129 to 209 kilometers (80 to 125 miles) wide, it is strategically located on transportation and communication routes between Europe and North Africa, and the Americas and Europe. Geographical location is one key to the long history of Portugal's three overseas empires, which stretched once from Morocco to the Moluccas and from lonely Sagres at Cape St. Vincent to Rio de Janeiro, Brazil. It is essential to emphasize the identity of its neighbors: on the north and east Portugal is bounded by Spain, its only neighbor, and by the Atlantic Ocean on the south and west. Portugal is the westernmost country of Western Europe, and its shape resembles a face, with Lisbon below the nose, staring into the

   Atlantic. No part of Portugal touches the Mediterranean, and its Atlantic orientation has been a response in part to turning its back on Castile and Léon (later Spain) and exploring, traveling, and trading or working in lands beyond the peninsula. Portugal was the pioneering nation in the Atlantic-born European discoveries during the Renaissance, and its diplomatic and trade relations have been dominated by countries that have been Atlantic powers as well: Spain; England (Britain since 1707); France; Brazil, once its greatest colony; and the United States.

   Today Portugal and its Atlantic islands have a population of roughly 10 million people. While ethnic homogeneity has been characteristic of it in recent history, Portugal's population over the centuries has seen an infusion of non-Portuguese ethnic groups from various parts of Europe, the Middle East, and Africa. Between 1500 and 1800, a significant population of black Africans, brought in as slaves, was absorbed in the population. And since 1950, a population of Cape Verdeans, who worked in menial labor, has resided in Portugal. With the influx of African, Goan, and Timorese refugees and exiles from the empire—as many as three quarters of a million retornados ("returned ones" or immigrants from the former empire) entered Portugal in 1974 and 1975—there has been greater ethnic diversity in the Portuguese population. In 2002, there were 239,113 immigrants legally residing in Portugal: 108,132 from Africa; 24,806 from Brazil; 15,906 from Britain; 14,617 from Spain; and 11,877 from Germany. In addition, about 200,000 immigrants are living in Portugal from eastern Europe, mainly from Ukraine. The growth of Portugal's population is reflected in the following statistics:

   Portugal did not produce an artist of sufficient ability to gain recognition outside the country until the 19th century. Domingos Antônio Segueira (1768-1837) became well known in Europe for his allegorical religious and historical paintings in a neoclassical style. Portuguese painting during the 19th century emphasized naturalism and did not keep abreast of artistic innovations being made in other European countries. Portugal's best painters lived abroad especially in France. The most successful was Amadeo Souza- Cardoso who, while living in Paris, worked with the modernists Modigliani, Georges Braque, and Juan Gris. Souza-Cardoso introduced modernism into Portuguese painting in the early 20th century. A sustained modernist movement did not develop in Portugal, however. Naturalism remained the dominant school, and Portugal remained isolated from international artistic trends, owing to Portugal's conservative artistic climate, which prevented new forms of art from taking root, and the lack of support from an artistically sophisticated, art-buying elite supported by a system of galleries and foundations.

   Interestingly, it was during the conservative Estado Novo that modernism began to take root in Portugal. As Prime Minister Antônio de Oliveira Salazar's secretary for national propaganda, Antônio Ferro, a writer, journalist, and cultural leader who admired Mussolini, encouraged the government to allow modern artists to create the heroic imagery of the Estado Novo following the Italian model that linked fascism with futurism. The most important Portuguese artist of this period was Almada Negreiros, who did the murals on the walls of the legendary café A Brasileira in the Chiado district of Lisbon, the paintings at the Exposition of the Portuguese World (1940), and murals at the Lisbon docks. Other artists of note during this period included Mário Eloy (1900-51), who was trained in Germany and influenced by George Grosz and Otto Dix; Domingos Alvarez (1906-42); and Antônio Pedro (1909-66).

   During the 1950s, the Estado Novo ceased to encourage artists to collaborate, as Portuguese artists became more critical of the regime. The return to Portugal of Antônio Pedro in 1947 led to the emergence of a school of geometric abstract painting in Oporto and the reawakening of surrealism. The art deco styles of the 1930s gave way to surrealism and abstract expression.

   In the 1960s, links between Portugal's artistic community and the international art world strengthened. Conscription for the wars against the nationalist insurgencies in Angola, Mozambique, and Guinea- Bissau (1961-75) resulted in a massive exodus of Portugal's avante-garde artists to Europe to avoid military service. While abroad, artists such as Joaquin Rodrigo (1912-93), Paula Rego (1935-), João Cutileiro (1947-), and others forged links with British, French, Italian, and Spanish artistic communities.

   The Revolution of 25 April 1974 created a crisis for Portugal's artists. The market for works of art collapsed as left-wing governments, claiming that they had more important things to do (eliminate poverty, improve education), withdrew support for the arts. Artists declared their talents to be at the "service of the people," and a brief period of socialist realism prevailed. With the return of political stability and moderate governments during the 1980s, Portugal's commercial art scene revived, and a new period of creativity began. Disenchantment with the socialist realism (utopianism) of the Revolution and a deepening of individualism began to be expressed by Portuguese artists. Investment in the arts became a means of demonstrating one's wealth and social status, and an unprecedented number of art galleries opened, art auctions were held, and a new generation of artists became internationally recognized. In 1984, a museum of modern art was built by the Gulbenkian Foundation adjacent to its offices on the Avenida de Berna in Lisbon. A national museum of modern art was finally built in Oporto in 1988.

   In the 1980s, Portugal's new generation of painters blended post-conceptualism and subjectivism, as well as a tendency toward decon-structionism/reconstructionism, in their work. Artists such as Cabrita Reis (1956-), Pedro Calapez (1953-), José Pedro Croft (1957-), Rui Sanches (1955-), and José de Guimarães (1949-) gained international recognition during this period. Guimarães crosses African art themes with Western art; Sarmento invokes images of film, culture, photography, American erotica, and pulp fiction toward sex, violence, and pleasure; Reis evolved from a painter to a maker of installation artist using chipboard, plaster, cloth, glass, and electrical and plumbing materials.

   From the end of the 20th century and during the early years of the 21st century, Portugal's art scene has been in a state of crisis brought on by a declining art trade and a withdrawal of financial support by conservative governments. Although not as serious as the collapse of the 1970s, the current situation has divided the Portuguese artistic community between those, such as Cerveira Pito and Leonel Moura, who advocate a return to using primitive, strongly textured techniques and others such as João Paulo Feliciano (1963-), who paint constructivist works that poke fun at the relationship between art, money, society, and the creative process. Thus, at the beginning of the 21st century, the factors that have prevented Portuguese art from achieving and sustaining international recognition (the absence of a strong art market, depending too much on official state support, and the individualistic nature of Portuguese art production) are still to be overcome.

(1934-)

   Army major who planned and managed the military operational aspects of the military coup that overthrew the Estado Novo. A career army officer who entered his profession in the 1950s, he held important positions in several of the colonial wars in Portugal's African territories during 1961-74. Saraiva de Carvalho was born in Mozambique in 1934, and made it his life's ambition to become a stage actor. In his career, he was influenced by service with Portugal's most senior army officer, General Antônio de Spínola, who served the Estado Novo both as commissioner and commanding general of armed forces in the colony of Guinea- Bissau. Contact with African nationalist elements, as well as familiarity with increasi ngly available Marxist-Leninist literature both in Africa and in Portugal, transformed Saraiva de Carvalho into a maverick and revolutionary who sought to overthrow the Portuguese dictatorship at home by means of military intervention in politics through the Revolution of 25 April 1974.

   Known as "Otelo" (Othello) in the media and to much of the Portuguese public, Saraiva de Carvalho played a significant role in the period of 25 April 1974-25 November 1975, when the country experienced a leftist revolution and a trend toward a dictatorship of the Left. Eventually the head of COPCON, the Armed Forces Movement's special unit for enforcing "law and order" and for ensuring that the government was not overthrown by military insur-rectionism, Saraiva de Carvalho became a political personality in his own right. This somberly handsome figure became the darling of the radical Left, including anarchist factions.

   With the swing of the political pendulum away from the radical Left after the abortive leftist coup of 25 November 1975, Carvalho's military career was ended and his role in politics shifted. He was dismissed from the COPCON command, arrested, and held in prison for a period. After his release, he entered the political wilderness, unhappy that the unorthodox Marxist-Leninist revolution he envisioned for Portugal, was not happening. Still carrying the torch for the notion of a "Socialist paradise" in which the state would play only a small role, the hero of the Revolution of 25 April 1974 reentered politics and ran for president of the republic on two occasions. In 1976, he received a respectable 16 percent of the vote, but in the 1981 elections his vote was negligible. Accused of involvement in several terrorist factions' conspiracies and violence, Carvalho was arrested and imprisoned. After a long and sensational trial, "Otelo" was released and acquitted. Of all the memoirs of the 1974 Revolution, Alvorada em Abril (Reveille in April), his contribution, was the most charming and revealing.

Allen was the Resident Engineer for construction of the Delaware \& Hudson Canal and in 1828 was instructed by J.B. Jervis to visit England to purchase locomotives for the canal's rail extension. He drove the locomotive Stourbridge Lion, built by J.U. Rastrick, on its first trial on 9 August 1829, but weak track prevented its regular use.

Allen was present at the Rainhill Trials on the Liverpool \& Manchester Railway in October 1829. So was E.L.Miller, one of the promoters of the South Carolina Canal \& Rail Road Company, to which Allen was appointed Chief Engineer that autumn. Allen was influential in introducing locomotives to this railway, and the West Point Foundry built a locomotive for it to his design; it was the first locomotive built in the USA for sale. This locomotive, which bore some resemblance to Novelty, built for Rainhill by John Braithwaite and John Ericsson, was named Best Friend of Charleston. On Christmas Day 1830 it hauled the first scheduled steam train to run in America, carrying 141 passengers.

In 1832 the West Point Foundry built four double-ended, articulated 2–2–0+0–2–2 locomotives to Horatio Allen's design for the South Carolina railroad. From each end of a central firebox extended two boiler barrels side by side with common smokeboxes and chimneys; wheels were mounted on swivelling sub-frames, one at each end, beneath these boilers. Allen's principal object was to produce a powerful locomotive with a light axle loading.

Allen subsequently became a partner in Stillman, Allen \& Co. of New York, builders of marine engines, and in 1843 was President of the Erie Railroad.

Cayley was born into a well-to-do Yorkshire family living at Brompton Hall. He was encouraged to study mathematics, navigation and mechanics, particularly by his mother. In 1792 he succeeded to the baronetcy and took over the daunting task of revitalizing the run-down family estate.

The first aeronautical device made by Cayley was a copy of the toy helicopter invented by the Frenchmen Launoy and Bienvenu in 1784. Cayley's version, made in 1796, convinced him that a machine could "rise in the air by mechanical means", as he later wrote. He studied the aerodynamics of flight and broke away from the unsuccessful ornithopters of his predecessors. In 1799 he scratched two sketches on a silver disc: one side of the disc showed the aerodynamic force on a wing resolved into lift and drag, and on the other side he illustrated his idea for a fixed-wing aeroplane; this disc is preserved in the Science Museum in London. In 1804 he tested a small wing on the end of a whirling arm to measure its lifting power. This led to the world's first model glider, which consisted of a simple kite (the wing) mounted on a pole with an adjustable cruciform tail. A full-size glider followed in 1809 and this flew successfully unmanned. By 1809 Cayley had also investigated the lifting properties of cambered wings and produced a low-drag aerofoil section. His aim was to produce a powered aeroplane, but no suitable engines were available. Steam-engines were too heavy, but he experimented with a gunpowder motor and invented the hot-air engine in 1807. He published details of some of his aeronautical researches in 1809–10 and in 1816 he wrote a paper on airships. Then for a period of some twenty-five years he was so busy with other activities that he largely neglected his aeronautical researches. It was not until 1843, at the age of 70, that he really had time to pursue his quest for flight. The Mechanics' Magazine of 8 April 1843 published drawings of "Sir George Cayley's Aerial Carriage", which consisted of a helicopter design with four circular lifting rotors—which could be adjusted to become wings—and two pusher propellers. In 1849 he built a full-size triplane glider which lifted a boy off the ground for a brief hop. Then in 1852 he proposed a monoplane glider which could be launched from a balloon. Late in 1853 Cayley built his "new flyer", another monoplane glider, which carried his coachman as a reluctant passenger across a dale at Brompton, Cayley became involved in public affairs and was MP for Scarborough in 1832. He also took a leading part in local scientific activities and was co-founder of the British Association for the Advancement of Science in 1831 and of the Regent Street Polytechnic Institution in 1838.
