  • 22 Fairbairn, William

    SUBJECT AREA: Ports and shipping
    [br]
    b. 19 February 1789 Kelso, Roxburghshire, Scotland
    d. 18 August 1874 Farnham, Surrey, England
    [br]
    Scottish engineer and shipbuilder, pioneer in the use of iron in structures.
    [br]
    Born in modest circumstances, Fairbairn nevertheless enjoyed a broad and liberal education until around the age of 14. Thereafter he served an apprenticeship as a millwright in a Northumberland colliery. This seven-year period marked him out as a man of determination and intellectual ability; he planned his life around the practical work of pit-machinery maintenance and devoted his limited free time to the study of mathematics, science and history as well as "Church, Milton and Recreation". Like many before and countless thousands after, he worked in London for some difficult and profitless years, and then moved to Manchester, the city he was to regard as home for the rest of his life. In 1816 he was married. Along with a workmate, James Lillie, he set up a general engineering business, which steadily enlarged and ultimately involved both shipbuilding and boiler-making. The partnership was dissolved in 1832 and Fairbairn continued on his own. Consultancy work commissioned by the Forth and Clyde Canal led to the construction of iron steamships by Fairbairn for the canal; one of these, the PS Manchester was lost in the Irish Sea (through the little-understood phenomenon of compass deviation) on her delivery voyage from Manchester to the Clyde. This brought Fairbairn to the forefront of research in this field and confirmed him as a shipbuilder in the novel construction of iron vessels. In 1835 he operated the Millwall Shipyard on the Isle of Dogs on the Thames; this is regarded as one of the first two shipyards dedicated to iron production from the outset (the other being Tod and MacGregor of Glasgow). Losses at the London yard forced Fairbairn to sell off, and the yard passed into the hands of John Scott Russell, who built the I.K. Brunel -designed Great Eastern on the site. However, his business in Manchester went from strength to strength: he produced an improved Cornish boiler with two firetubes, known as the Lancashire boiler; he invented a riveting machine; and designed the beautiful swan-necked box-structured crane that is known as the Fairbairn crane to this day.
    Throughout his life he advocated the widest use of iron; he served on the Admiralty Committee of 1861 investigating the use of this material in the Royal Navy. In his later years he travelled widely in Europe as an engineering consultant and published many papers on engineering. His contribution to worldwide engineering was recognized during his lifetime by the conferment of a baronetcy by Queen Victoria.

    Bibliography
    Fairbairn wrote many papers on a wide range of engineering subjects from water-wheels to iron metallurgy and from railway brakes to the strength of iron ships. In 1856 he contributed the article on iron to the 8th edition of Encyclopaedia Britannica.

  • 24 Saldanha, Duke of

    (1790-1876)
       Born João Carlos de Saldanha Oliveira Daun, and later called duke, marshal, count, and marquis of Saldanha, he pursued a military career and personified military intervention in 19th-century politics. Saldanha fought against the French in the Peninsular War, as well as in conflicts in Uruguay and Brazil, and he backed the constitutional monarchist cause of King Pedro IV. Perhaps the most famous of career officers during the century, in his younger years he was often in exile. Critics quipped that his true name was "Dom João VII" for his imperious manner. As minister and prime minister in various liberal governments after 1851, his name later became used as a generic term for an impetuously planned military coup, a "Saldanhada," meaning a military golpe almost whimsical in spirit, carried out by a wild, headstrong general.
       A soldier from the tender age of 14, Saldanha was a much-discussed figure during various generations of soldiers and politicians. The writer Oliveira Martins later described the man as "a liberal and Portuguese Cid," after El Cid, the Castilian crusading warrior who fought Muslims in medieval Spain. For the constitutional liberal cause of Regent Dom Pedro, Saldanha's personal valor and military prowess were essential in the civil wars, and his prestige in the military was important in the era of the Regeneration of 1851-70; however, this officer lacked political ideas and was out of his element in governance. Queen Maria II, however, in part owed her throne to the force of this military personality who had become a general at age 27. In later life, Saldanha, loaded with honors and freighted with medals, served as Portugal's ambassador in Paris and London, in which city he died at his last post.

  • 25 Deville, Henri Etienne Sainte-Claire

    SUBJECT AREA: Metallurgy
    [br]
    b. 11 March 1818 St Thomas, Virgin Islands
    d. 1 July 1881 Boulogne-sur-Seine, France
    [br]
    French chemist and metallurgist, pioneer in the large-scale production of aluminium and other light metals.
    [br]
    Deville was the son of a prosperous shipowner with diplomatic duties in the Virgin Islands. With his elder brother Charles, who later became a distinguished physicist, he was sent to Paris to be educated. He took his degree in medicine in 1843, but before that he had shown an interest in chemistry, due particularly to the lectures of Thenard. Two years later, with Thenard's influence, he was appointed Professor of Chemistry at Besançon. In 1851 he was able to return to Paris as Professor at the Ecole Normale Supérieure. He remained there for the rest of his working life, greatly improving the standard of teaching, and his laboratory became one of the great research centres of Europe. His first chemical work had been in organic chemistry, but he then turned to inorganic chemistry, specifically to improve methods of producing the new and little-known metal aluminium. Essentially, the process consisted of forming sodium aluminium trichloride and reducing it with sodium to metallic aluminium. He obtained sodium in sufficient quantity by reducing sodium carbonate with carbon. In 1855 he exhibited specimens of the metal at the Paris Exhibition, and the same year Napoleon III asked to see them, with a view to using it for breastplates for the Army and for spoons and forks for State banquets. With the resulting government support, he set up a pilot plant at Jarvel to develop the process, and then set up a small company, the Société d'Aluminium at Nan terre. This raised the output of this attractive and useful metal, so it could be used more widely than for the jewellery to which it had hitherto been restricted. Large-scale applications, however, had to await the electrolytic process that began to supersede Deville's in the 1890s. Deville extended his sodium reduction method to produce silicon, boron and the light metals magnesium and titanium. His investigations into the metallurgy of platinum revolutionized the industry and led in 1872 to his being asked to make the platinum-iridium (90–10) alloy for the standard kilogram and metre. Deville later carried out important work in high-temperature chemistry. He grieved much at the death of his brother Charles in 1876, and his retirement was forced by declining health in 1880; he did not survive for long.
    [br]
    Bibliography
    Deville published influential books on aluminium and platinum; these and all his publications are listed in the bibliography in the standard biography by J.Gray, 1889, Henri Sainte-Claire Deville: sa vie et ses travaux, Paris.

  • 26 Mercer, John

    SUBJECT AREA: Textiles
    [br]
    b. 21 February 1791 Great Harwood, Lancashire, England
    d. 30 November 1866 Oakenshaw, Lancashire, England
    [br]
    English pioneer in textile chemistry.
    [br]
    Mercer began work at the age of 9 as a bobbinwinder and then a hand-loom weaver. He had no formal education in chemistry but taught himself and revealed remarkable ability in both theoretical and applied aspects of the subject. He became the acknowledged "father of textile chemistry" and the Royal Society elected him Fellow in 1850. His name is remembered in connection with the lustrous "mercerized" cotton which, although not developed commercially until 1890, arose from his discovery, c. 1844, of the effect of caustic soda on cotton linters. He also discovered that cotton could be dissolved in a solution of copper oxide in ammonia, a phenomenon later exploited in the manufacture of artificial silk. As a youth, Mercer experimented at home with dyeing processes and soon acquired sufficient skill to set up as an independent dyer. Most of his working life was, however, spent with the calico-printing firm of Oakenshaw Print Works in which he eventually became a partner, and it was there that most of his experimental work was done. The association was a very appropriate one, for it was a member of this firm's staff who first recognized Mercer's potential talent and took the trouble in his spare time to teach him reading, writing and arithmetic. Mercer developed manganese-bronze colours and researched into catalysis and the ferrocyanides. Among his innovations was the chlorination of wool in order to make it print as easily as cotton. It was many years later that it was realized that this treatment also conferred valuable shrink-resisting qualities. Becoming interested in photochemistry, he devised processes for photographic printing on fabric. Queen Victoria was presented with a handkerchief printed in this way when she visited the Great Exhibition of 1851, of which Mercer was a juror. A photograph of Mercer himself on cloth is preserved in the Museum of Science and Industry in Manchester. He presented papers to the British Association and was a member of the Chemical Society.

    b. 1799 Auchterhouse, Scotland
    d. 22 April 1869 Carmyllie, Scotland
    [br]
    Scottish inventor of the first successful reaping machine.
    [br]
    The son of a Forfarshire tenant farmer, Patrick Bell obtained an MA from the University of St Andrews. His early association with farming kindled an interest in engineering and mechanics and he was to maintain a workshop not only on his father's farm, but also, in later life, at the parsonage at Carmyllie.
    He was still studying divinity when he invented his reaping machine. Using garden shears as the basis of his design, he built a model in 1827 and a full-scale prototype the following year. Not wishing the machine to be seen during his early experiments, he and his brother planted a sheaf of oats in soil laid out in a shed, and first tried the machine on this. It cut well enough but left the straw in a mess behind it. A canvas belt system was devised and another secret trial in the barn was followed by a night excursion into a field, where corn was successfully harvested.
    Two machines were at work during 1828, apparently achieving a harvest rate of one acre per hour. In 1832 there were ten machines at work, and at least another four had been sent to the United States by this time. Despite their success Bell did not patent his design, feeling that the idea should be given free to the world. In later years he was to regret the decision, feeling that the many badly-made imitations resulted in its poor reputation and prevented its adoption.
    Bell's calling took precedence over his inventive interests and after qualifying he went to Canada in 1833, spending four years in Fergus, Ontario. He later returned to Scotland and be-came the minister at Carmyllie, with a living of £150 per annum.

    SUBJECT AREA: Telecommunications
    [br]
    b. 27 April 1791 Charlestown, Massachusetts, USA
    d. 2 April 1872 New York City, New York, USA
    [br]
    American portrait painter and inventor, b est known for his invention of the telegraph and so-called Morse code.
    [br]
    Following early education at Phillips Academy, Andover, at the age of 14 years Morse went to Yale College, where he developed interests in painting and electricity. Upon graduating in 1810 he became a clerk to a Washington publisher and a pupil of Washington Allston, a well-known American painter. The following year he travelled to Europe and entered the London studio of another American artist, Benjamin West, successfully exhibiting at the Royal Academy as well as winning a prize and medal for his sculpture. Returning to Boston and finding little success as a "historical-style" painter, he built up a thriving portrait business, moving in 1818 to Charleston, South Carolina, where three years later he established the (now defunct) South Carolina Academy of Fine Arts. In 1825 he was back in New York, but following the death of his wife and both of his parents that year, he embarked on an extended tour of European art galleries. In 1832, on the boat back to America, he met Charles T.Jackson, who told him of the discovery of the electromagnet and fired his interest in telegraphy to the extent that Morse immediately began to make suggestions for electrical communications and, apparently, devised a form of printing telegraph. Although he returned to his painting and in 1835 was appointed the first Professor of the Literature of Art and Design at the University of New York City, he began to spend more and more time experimenting in telegraphy. In 1836 he invented a relay as a means of extending the cable distance over which telegraph signals could be sent. At this time he became acquainted with Alfred Vail, and the following year, when the US government published the requirements for a national telegraph service, they set out to produce a workable system, with finance provided by Vail's father (who, usefully, owned an ironworks). A patent was filed on 6 October 1837 and a successful demonstration using the so-called Morse code was given on 6 January 1838; the work was, in fact, almost certainly largely that of Vail. As a result of the demonstration a Bill was put forward to Congress for $30,000 for an experimental line between Washington and Baltimore. This was eventually passed and the line was completed, and on 24 May 1844 the first message, "What hath God wrought", was sent between the two cities. In the meantime Morse also worked on the insulation of submarine cables by means of pitch tar and indiarubber.
    With success achieved, Morse offered his invention to the Government for $100,000, but this was declined, so the invention remained in private hands. To exploit it, Morse founded the Magnetic Telephone Company in 1845, amalgamating the following year with the telegraph company of a Henry O'Reilly to form Western Union. Having failed to obtain patents in Europe, he now found himself in litigation with others in the USA, but eventually, in 1854, the US Supreme Court decided in his favour and he soon became very wealthy. In 1857 a proposal was made for a telegraph service across the whole of the USA; this was completed in just over four months in 1861. Four years later work began on a link to Europe via Canada, Alaska, the Aleutian Islands and Russia, but it was abandoned with the completion of the transatlantic cable, a venture in which he also had some involvement. Showered with honours, Morse became a generous philanthropist in his later years. By 1883 the company he had created was worth $80 million and had a virtual monopoly in the USA.

    [br]
    b. 1720 Parr (?), near St Helens, Lancashire, England
    d. 30 July 1812 Liverpool, England
    [br]
    English canal and dock engineer who was responsible for the first true canal, as distinct from a canalized river, in England.
    [br]
    Little is known of Berry's early life, but it is certain that he knew the district around St Helens intimately, which was of assistance to him in his later canal works. He became Clerk and Assistant to Thomas Steers and proved his natural engineering ability in helping Steers in both the construction of the Newry navigation in Ireland and his supervision of the construction of Salthouse Dock in Liverpool. On Steers's death in 1750 Berry was appointed, at the age of 30, Dock Engineer for Liverpool Docks, and completed the Salthouse Dock three years later. In 1755 he was allowed by the Liverpool Authority—presumably because his full-time service was not required at the docks at that time—to survey and construct the Sankey Brook Navigation (otherwise known as the St Helens Canal), which was completed in 1757. Berry was instructed to make the brook navigable, but with the secret consent and connivance of one of the proprietors he built a lateral canal, the work commencing on 5 September 1755. This was the first dead-water canal in the country, as distinct from an improved river navigation, and preceded Brindley's Bridgewater Canal by some five or six years. On the canal he also constructed at Blackbrook the first pair of staircase locks to be built in England.
    Berry later advised on improvements to the Weaver Navigation, and his design for the new locks was accepted. He also carried out in 1769 a survey for a Leeds and Liverpool Canal, but this was not proceeded with and it was left to others to construct this canal. He advised turnpike trustees on bridge construction, but his main work was in Liverpool dock construction and between 1767 and 1771 he built the George's Dock. His final dock work was King's Dock, which was opened on 3 October 1788; he resigned at the age of 68 when the dock was completed. He lived for another 24 years, during which he was described in the local directories as "gentleman" instead of "engineer" or "surveyor" as he had been previously.

  • 30 Philosophy

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

    Scottish industrialist whose Tyneside shipyard was an early constituent of what became the Vickers Shipbuilding Group.
    [br]
    Mitchell's early education commenced at Ledingham's Academy, Correction Wynd, Aberdeen, and from there he became a premium apprentice at the Footdee Engineering Works of Wm Simpson \& Co. Despite being employed for around twelve hours each day, Mitchell matriculated at Marischal College (now merged with King's College to form the University of Aberdeen). He did not graduate, although in 1840 he won the chemistry prize. On the completion of his apprenticeship, like Andrew Leslie (founder of Hawthorn Leslie) and other young Aberdonians he moved to Tyneside, where most of his working life was spent. From 1842 until 1844 he worked as a draughtsman for his friend Coutts, who had a shipyard at Low Walker, before moving on to the drawing offices of Maudslay Sons and Field of London, then one of the leading shipbuilding and engineering establishments in the UK. While in London he studied languages, acquiring a skill that was to stand him in good stead in later years. In 1852 he returned to the North East and set up his own iron-ship building yard at Low Walker near Newcastle. Two years later he married Anne Swan, the sister of the two young men who were to found the company now known as Swan Hunter Ltd. The Mitchell yard grew in size and reputation and by the 1850s he was building for the Russian Navy and Merchant Marine as well as advising the Russians on their shipyards in St Petersburg. In 1867 the first informal business arrangement was concluded with Armstrongs for the supply of armaments for ships; this led to increased co-operation and ultimately in 1882 to the merger of the two shipyards as Sir W.G.Armstrong Mitchell \& Co. At the time of the merger, Mitchell had launched 450 ships in twenty-nine years. In 1886 the new company built the SS Gluckauf, the world's first bulk oil tanker. After ill health in 1865 Mitchell reduced his workload and lived for a while in Surbiton, London, but returned to Tyneside to a new house at Jesmond. In his later years he was a generous benefactor to many good causes in Tyneside and Aberdeen, to the Church and to the University of Aberdeen.

    d. 20 December 1855 Dorking, Surrey, England
    [br]
    English master builder and founder of the first building firm of modern type.
    [br]
    He started his working life as a carpenter at a time when work in different trades such as bricklaying, masonry, carpentry and plumbing was subcontracted. The system had worked well enough until about 1800, but when large-scale development was required, as in the nineteenth century, it showed itself to be inefficient and slow. To avoid long delays in building, Cubitt bought land and established workshops, founding a firm that employed all the craftsmen necessary to the building trade on a permanent-wage basis. To keep his firm financially solvent he had to provide continuous work for his staff, which he achieved by large-scale, speculative building even while maintaining high architectural standards.
    Cubitt performed a major service to London, with many of his houses, squares and terraces still surviving as sound and elegant as they were over 150 years ago in the large estates he laid out. His most ambitious enterprise was Belgravia, where he built 200 imposing houses for the aristocracy upon an area of previously swampy land that he leased from Lord Grosvenor. His houses expose as inferior much of the later phases of development which surround them. All his life Cubitt used his influence to combat the abuses of architecture, building and living standards to which speculative building is heir. He was especially interested in drainage, smoke control and London's sewage arrangement, and constantly worked to improve these. He supplied first-class amenities in the way of land drainage, sewage disposal, street lighting and roads, and his own houses were soundly built, pleasant to live in and created to last.

    [br]
    b. 7 August 1783 Duffield, Derbyshire, England
    d. 18 January 1861 Tiverton, Devonshire, England
    [br]
    English inventor of the bobbin-net lace machine.
    [br]
    Heathcote was the son of a small farmer who became blind, obliging the family to move to Long Whatton, near Loughborough, c.1790. He was apprenticed to W.Shepherd, a hosiery-machine maker, and became a frame-smith in the hosiery industry. He moved to Nottingham where he entered the employment of an excellent machine maker named Elliott. He later joined William Caldwell of Hathern, whose daughter he had married. The lace-making apparatus they patented jointly in 1804 had already been anticipated, so Heathcote turned to the problem of making pillow lace, a cottage industry in which women made lace by arranging pins stuck in a pillow in the correct pattern and winding around them thread contained on thin bobbins. He began by analysing the complicated hand-woven lace into simple warp and weft threads and found he could dispense with half the bobbins. The first machine he developed and patented, in 1808, made narrow lace an inch or so wide, but the following year he made much broader lace on an improved version. In his second patent, in 1809, he could make a type of net curtain, Brussels lace, without patterns. His machine made bobbin-net by the use of thin brass discs, between which the thread was wound. As they passed through the warp threads, which were arranged vertically, the warp threads were moved to each side in turn, so as to twist the bobbin threads round the warp threads. The bobbins were in two rows to save space, and jogged on carriages in grooves along a bar running the length of the machine. As the strength of this fabric depended upon bringing the bobbin threads diagonally across, in addition to the forward movement, the machine had to provide for a sideways movement of each bobbin every time the lengthwise course was completed. A high standard of accuracy in manufacture was essential for success. Called the "Old Loughborough", it was acknowledged to be the most complicated machine so far produced. In partnership with a man named Charles Lacy, who supplied the necessary capital, a factory was established at Loughborough that proved highly successful; however, their fifty-five frames were destroyed by Luddites in 1816. Heathcote was awarded damages of £10,000 by the county of Nottingham on the condition it was spent locally, but to avoid further interference he decided to transfer not only his machines but his entire workforce elsewhere and refused the money. In a disused woollen factory at Tiverton in Devonshire, powered by the waters of the river Exe, he built 300 frames of greater width and speed. By continually making inventions and improvements until he retired in 1843, his business flourished and he amassed a large fortune. He patented one machine for silk cocoon-reeling and another for plaiting or braiding. In 1825 he brought out two patents for the mechanical ornamentation or figuring of lace. He acquired a sound knowledge of French prior to opening a steam-powered lace factory in France. The factory proved to be a successful venture that lasted many years. In 1832 he patented a monstrous steam plough that is reputed to have cost him over £12,000 and was claimed to be the best in its day. One of its stated aims was "improved methods of draining land", which he hoped would develop agriculture in Ireland. A cable was used to haul the implement across the land. From 1832 to 1859, Heathcote represented Tiverton in Parliament and, among other benefactions, he built a school for his adopted town.

    d. 12 February 1874 South Kensington, London, England
    [br]
    English inventor of the screw propeller.
    [br]
    Smith was the only son of Charles Smith, Postmaster at Hythe, and his wife Sarah (née Pettit). After education at a private school in Ashford, Kent, he took to farming, first on Romney Marsh, then at Hendon, Middlesex. As a boy, he showed much skill in the construction of model boats, especially in devising their means of propulsion. He maintained this interest into adult life and in 1835 he made a model propelled by a screw driven by a spring. This worked so well that he became convinced that the screw propeller offered a better method of propulsion than the paddle wheels that were then in general use. This notion so fired his enthusiasm that he virtually gave up farming to devote himself to perfecting his invention. The following year he produced a better model, which he successfully demonstrated to friends on his farm at Hendon and afterwards to the public at the Adelaide Gallery in London. On 31 May 1836 Smith was granted a patent for the propulsion of vessels by means of a screw.
    The idea of screw propulsion was not new, however, for it had been mooted as early as the seventeenth century and since then several proposals had been advanced, but without successful practical application. Indeed, simultaneously but quite independently of Smith, the Swedish engineer John Ericsson had invented the ship's propeller and obtained a patent on 13 July 1836, just weeks after Smith. But Smith was completely unaware of this and pursued his own device in the belief that he was the sole inventor.
    With some financial and technical backing, Smith was able to construct a 10 ton boat driven by a screw and powered by a steam engine of about 6 hp (4.5 kW). After showing it off to the public, Smith tried it out at sea, from Ramsgate round to Dover and Hythe, returning in stormy weather. The screw performed well in both calm and rough water. The engineering world seemed opposed to the new method of propulsion, but the Admiralty gave cautious encouragement in 1839 by ordering that the 237 ton Archimedes be equipped with a screw. It showed itself superior to the Vulcan, one of the fastest paddle-driven ships in the Navy. The ship was put through its paces in several ports, including Bristol, where Isambard Kingdom Brunel was constructing his Great Britain, the first large iron ocean-going vessel. Brunel was so impressed that he adapted his ship for screw propulsion.
    Meanwhile, in spite of favourable reports, the Admiralty were dragging their feet and ordered further trials, fitting Smith's four-bladed propeller to the Rattler, then under construction and completed in 1844. The trials were a complete success and propelled their lordships of the Admiralty to a decision to equip twenty ships with screw propulsion, under Smith's supervision.
    At last the superiority of screw propulsion was generally accepted and virtually universally adopted. Yet Smith gained little financial reward for his invention and in 1850 he retired to Guernsey to resume his farming life. In 1860 financial pressures compelled him to accept the position of Curator of Patent Models at the Patent Museum in South Kensington, London, a post he held until his death. Belated recognition by the Government, then headed by Lord Palmerston, came in 1855 with the grant of an annual pension of £200. Two years later Smith received unofficial recognition when he was presented with a national testimonial, consisting of a service of plate and nearly £3,000 in cash subscribed largely by the shipbuilding and engineering community. Finally, in 1871 Smith was honoured with a knighthood.

    b. 17 June 1832 London, England
    d. 4 April 1919 London, England
    [br]
    English chemist and physicist who carried out studies of electrical discharges and cathode rays in rarefied gases, leading to the development of the cathode ray tube; discoverer of the element thallium and the principle of the Crookes radiometer.
    [br]
    Crookes entered the Royal College of Chemistry at the age of 15, and from 1850 to 1854 held the appointment of Assistant at the college. In 1854 he became Superintendent of the Meteorological Department at the Radcliffe Observatory in Oxford. He moved to a post at the College of Science in Chester the following year. Soon after this he inherited a large fortune and set up his own private laboratory in London. There he studied the nature of electrical discharges in gases at low pressure and discovered the dark space (later named after him) that surrounds the negative electrode, or cathode. He also established that the rays produced in the process (subsequently shown by J.J.Thompson to be a stream of electrons) not only travelled in straight lines, but were also capable of producing heat and/or light upon impact with suitable anode materials. Using a variety of new methods to investigate these "cathode" rays, he applied them to the spectral analysis of compounds of selenium and, as a result, in 1861 he discovered the element thallium, finally establishing its atomic weight in 1873. Following his discovery of thallium, he became involved in two main lines of research: the properties of rarified gases, and the investigation of the elements of the "rare earths". It was also during these experiments that he discovered the principle of the Crookes radiometer, a device in which light is converted into rotational motion and which used to be found frequently in the shop windows of English opticians. Also among the fruits of this work were the Crookes tubes and the development of spectacle lenses with differential ranges of radiational absorption. In the 1870s he became interested in spiritualism and acquired a reputation for his studies of psychic phenomena, but at the turn of the century he returned to traditional scientific investigations. In 1892 he wrote about the possibility of wireless telegraphy. His work in the field of radioactivity led to the invention of the spinthariscope, an early type of detector of alpha particles. In 1900 he undertook investigations into uranium which led to the study of scintillation, an important tool in the study of radioactivity.
    While the theoretical basis of his work has not stood the test of time, his material discoveries, observations and investigations of new facts formed a basis on which others such as J.J. Thomson were to develop subatomic theory. His later involvement in the investigation of spiritualism led to much criticism, but could be justified on the basis of a belief in the duty to investigate all phenomena.

    Canadian (naturalized American) electrical engineer, pioneer of the quartz clock.
    [br]
    Marrison received his high-school education at Kingston Collegiate Institute, Ontario, and in 1914 he entered Queen's University in Kingston. He graduated in Engineering Physics in 1920, his college career having been interrupted by war service in the Royal Flying Corps. During his service in the Flying Corps he worked on radio, and when he returned to Kingston he established his own transmitter. This interest in radio was later to influence his professional life.
    In 1921 he entered Harvard University, where he obtained an MA, and shortly afterwards he joined the Western Electric Company in New York to work on the recording of sound on film. In 1925 he transferred to Western Electric's Bell Laboratory, where he began what was to become his life's work: the development of frequency standards for radio transmission. In 1922 Cady had used the elastic vibration of a quartz crystal to control the frequency of a valve oscillator, but at that time there was no way of counting and displaying the number of vibrations as the frequency was too high. In 1927 Marrison succeeded in dividing the frequency electronically until it was low enough to drive a synchronous motor. Although his purpose was to determine the frequency accurately by counting the number of vibrations that occurred in a given time, he had incidentally produced the first quartz-crystal -ontrolled clock. The results were sufficiently encouraging for him to build an improved version the following year, specifically as a time and frequency standard.

    [br]
    b. 22 March 1840 Cincinnati, Ohio, USA
    d. 18 July 1926
    [br]
    American mechanical engineer, pioneer in experiments with magnetic recording.
    [br]
    Of English descent, Smith embarked on an education in mechanical engineering, graduating from West Jersey Academy, Bridgeton, New Jersey, in 1859. In 1863 he established a machine shop in Bridgeton, New Jersey, that became the Ferracute Machine Company in 1877, eventually specializing in the manufacture of presses for metalworking. He seems to have subscribed to design principles considered modern even in the 1990s, "always giving attention to the development of artistic form in combination with simplicity, and with massive strength where required" (bibliographic reference below). He was successful in his business, and developed and patented a large number of mechanical constructions.
    Inspired by the advent of the phonograph of Edison, in 1878 Smith obtained the tin-foil mechanical phonograph, analysed its shortcomings and performed some experiments in magnetic recording. He filed a caveat in the US Patent Office in order to be protected while he "reduced the invention to practice". However, he did not follow this trail. When there was renewed interest in practical sound recording and reproduction in 1888 (the constructions of Berliner and Bell \& Tainter), Smith published an account of his experiments in the journal Electrical World. In a corrective letter three weeks later it is clear that he was aware of the physical requirements for the interaction between magnetic coil and magnetic medium, but his publications also indicate that he did not as such obtain reproduction of recorded sound.
    Smith did not try to develop magnetic recording, but he felt it imperative that he be given credit for conceiving the idea of it. When accounts of Valdemar Poulsen's work were published in 1900, Smith attempted to prove some rights in the invention in the US Patent Office, but to no avail.
    He was a highly respected member of both his community and engineering societies, and in later life became interested in the anti-slavery cause that had also been close to the heart of his parents, as well as in the YMCA movement and in women's suffrage.

    Apart from numerous technical papers, he wrote the book Press Working of Metals, 1896. His accounts on the magnetic recording experiments were "Some possible forms of phonograph", Electrical World (8 September 1888): 161 ff, and "Letter to the Editor", Electrical World (29 September 1888): 179.

    d. 1 February 1865 Grevenburg, near Höxter, Germany
    [br]
    German mining officer who introduced fish joints to deep-drilling.
    [br]
    The son of a mining officer, Oeynhausen started his career in the Prussian administration of the mining industry in 1816, immediately after he had finished his studies in natural sciences and mathematics at the University of Göttingen. From 1847 until his retirement he was a most effective head of state mines inspectorates, first in Silesia (Breslau; now Wroclaw, Poland), later in Westphalia (Dortmund). During his working life he served in all the important mining districts of Prussia, and travelled to mining areas in other parts of Germany, Belgium, France and Britain. In the 1820s, after visiting Glenck's well-known saltworks near Wimpfen, he was commissioned to search for salt deposits in Prussian territory, where he discovered the thermal springs south of Minden which later became the renowned spa carrying his name.
    With deeper drills, the increased weight of the rods made it difficult to disengage the drill on each stroke and made the apparatus self-destructive on impact of the drill. Oeynhausen, from 1834, used fish joints, flexible connections between the drill and the rods. Not only did they prevent destructive impact, but they also gave a jerk on the return stroke that facilitated disengagements. He never claimed to have invented the fish joints: in fact, they appeared almost simultaneously in Europe and in America at that time, and had been used since at least the seventeenth century in China, although they were unknown in the Western hemisphere.
    Using fish joints meant the start of a new era in deep-drilling, allowing much deeper wells to be sunk than before. Five weeks after Oeynhausen, K.G. Kind operated with a different kind of fish joint, and in 1845 another Prussian mining officer, Karl Leopold Fabian (1782–1855), Director of the salt inspectorate at Schönebeck, Elbe, improved the fish joints by developing a special device between the rod and the drill to enable the chisel, strengthened by a sinker bar, to fall onto the bottom of the hole without hindrance with a higher effect. The free-fall system became another factor in the outstanding results of deep-drilling in Prussia in the nineteenth century.

    [br]
    b. 23 August 1847 Sutton, Hull, England
    d. 7 September 1936 Hull, England
    [br]
    English oil engine pioneer.
    [br]
    William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.
    Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.
    Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.
    On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.
    Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.

    b. 14 (registered 13) February 1728 East Kilbride, Lanarkshire, Scotland
    d. 16 October 1793 London, England
    [br]
    Scottish surgeon and anatomist, pioneer of experimental methods in medicine and surgery.
    [br]
    The younger brother of William Hunter (1718–83), who was of great distinction but perhaps of slightly less achievement in similar fields, he owed much of his early experience to his brother; William, after a period at Glasgow University, moved to St George's Hospital, London. In his later teens, John assisted a brother-in-law with cabinet-making. This appears to have contributed to the lifelong mechanical skill which he displayed as a dissector and surgeon. This skill was particularly obvious when, after following William to London in 1748, he held post at a number of London teaching hospitals before moving to St George's in 1756. A short sojourn at Oxford in 1755 appears to have been unfruitful.
    Despite his deepening involvement in the study of comparative anatomy, facilitated by the purchase of animals from the Tower menagerie and travelling show people, he accepted an appointment as a staff surgeon in the Army in 1760, participating in the expedition to Belle Isle and also serving in Portugal. He returned home with over 300 specimens in 1763 and, until his appointment as Surgeon to St George's in 1768, was heavily involved in the examination of this and other material, as well as in studies of foetal testicular descent, placental circulation, the nature of pus and lymphatic circulation. In 1772 he commenced lecturing on the theory and practice of surgery, and in 1776 he was appointed Surgeon-Extraordinary to George III.
    He is rightly regarded as the founder of scientific surgery, but his knowledge was derived almost entirely from his own experiments and observations. His contemporaries did not always accept or understand the concepts which led to such aphorisms as, "to perform an operation is to mutilate a patient we cannot cure", and his written comment to his pupil Jenner: "Why think. Why not trie the experiment". His desire to establish the aetiology of gonorrhoea led to him infecting himself, as a result of which he also contracted syphilis. His ensuing account of the characteristics of the disease remains a classic of medicine, although it is likely that the sequelae of the condition brought about his death at a relatively early age. From 1773 he suffered recurrent anginal attacks of such a character that his life "was in the hands of any rascal who chose to annoy and tease him". Indeed, it was following a contradiction at a board meeting at St George's that he died.
    By 1788, with the death of Percival Pott, he had become unquestionably the leading surgeon in Britain, if not Europe. Elected to the Royal Society in 1767, the extraordinary variety of his collections, investigations and publications, as well as works such as the "Treatise on the natural history of the human teeth" (1771–8), gives testimony to his original approach involving the fundamental and inescapable relation of structure and function in both normal and disease states. The massive growth of his collections led to his acquiring two houses in Golden Square to contain them. It was his desire that after his death his collection be purchased and preserved for the nation. It contained 13,600 specimens and had cost him £70,000. After considerable delay, Par-liament voted inadequate sums for this purpose and the collection was entrusted to the recently rechartered Royal College of Surgeons of England, in whose premises this remarkable monument to the omnivorous and eclectic activities of this outstanding figure in the evolution of medicine and surgery may still be seen. Sadly, some of the collection was lost to bombing during the Second World War. His surviving papers were also extensive, but it is probable that many were destroyed in the early nineteenth century.
