Adamson was apprenticed between 1835 and 1841 to Timothy Hackworth, then Locomotive Superintendent on the Stockton \& Darlington Railway. After this he was appointed Draughtsman, then Superintendent Engineer, at that railway's locomotive works until in 1847 he became Manager of Shildon Works. In 1850 he resigned and moved to act as General Manager of Heaton Foundry, Stockport. In the following year he commenced business on his own at Newton Moor Iron Works near Manchester, where he built up his business as an iron-founder and boilermaker. By 1872 this works had become too small and he moved to a 4 acre (1.6 hectare) site at Hyde Junction, Dukinfield. There he employed 600 men making steel boilers, heavy machinery including mill engines fitted with the American Wheelock valve gear, hydraulic plant and general millwrighting. His success was based on his early recognition of the importance of using high-pressure steam and steel instead of wrought iron. In 1852 he patented his type of flanged seam for the firetubes of Lancashire boilers, which prevented these tubes cracking through expansion. In 1862 he patented the fabrication of boilers by drilling rivet holes instead of punching them and also by drilling the holes through two plates held together in their assembly positions. He had started to use steel for some boilers he made for railway locomotives in 1857, and in 1860, only four years after Bessemer's patent, he built six mill engine boilers from steel for Platt Bros, Oldham. He solved the problems of using this new material, and by his death had made c.2,800 steel boilers with pressures up to 250 psi (17.6 kg/cm²).

He was a pioneer in the general introduction of steel and in 1863–4 was a partner in establishing the Yorkshire Iron and Steel Works at Penistone. This was the first works to depend entirely upon Bessemer steel for engineering purposes and was later sold at a large profit to Charles Cammell \& Co., Sheffield. When he started this works, he also patented improvements both to the Bessemer converters and to the engines which provided their blast. In 1870 he helped to turn Lincolnshire into an important ironmaking area by erecting the North Lincolnshire Ironworks. He was also a shareholder in ironworks in South Wales and Cumberland.

He contributed to the development of the stationary steam engine, for as early as 1855 he built one to run with a pressure of 150 psi (10.5 kg/cm) that worked quite satisfactorily. He reheated the steam between the cylinders of compound engines and then in 1861–2 patented a triple-expansion engine, followed in 1873 by a quadruple-expansion one to further economize steam. In 1858 he developed improved machinery for testing tensile strength and compressive resistance of materials, and in the same year patents for hydraulic lifting jacks and riveting machines were obtained.

He was a founding member of the Iron and Steel Institute and became its President in 1888 when it visited Manchester. The previous year he had been President of the Institution of Civil Engineers when he was presented with the Bessemer Gold Medal. He was a constant contributor at the meetings of these associations as well as those of the Institution of Mechanical Engineers. He did not live to see the opening of one of his final achievements, the Manchester Ship Canal. He was the one man who, by his indomitable energy and skill at public speaking, roused the enthusiasm of the people in Manchester for this project and he made it a really practical proposition in the face of strong opposition.

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.

After working as a millwright in Halifax, Riley found employment at the Ormesby Ironworks in Middlesbrough until, in 1869, he became manager of the Askam Ironworks in Cumberland. Three years later, in 1872, he was appointed Blast-furnace Manager at the pioneering Siemens Steel Company's works at Landore, near Swansea in South Wales. Using Spanish ore, he produced the manganese-rich iron (spiegeleisen) required as an additive to make satisfactory steel. Riley was promoted in 1874 to be General Manager at Landore, and he worked with William Siemens to develop the use of the latter's regenerative furnace for the production of open-hearth steel. He persuaded Welsh makers of tin plate to use sheets rolled from lowcarbon (mild) steel instead of from charcoal iron and, partly by publishing some test results, he was instrumental in influencing the Admiralty to build two naval vessels of mild steel, the Mercury and the Iris.

In 1878 Riley moved north on his appointment as General Manager of the Steel Company of Scotland, a firm closely associated with Charles Tennant that was formed in 1872 to make steel by the Siemens process. Already by 1878, fourteen Siemens melting furnaces had been erected, and in that year 42,000 long tons of ingots were produced at the company's Hallside (Newton) Works, situated 8 km (5 miles) south-east of Glasgow. Under Riley's leadership, steelmaking in open-hearth furnaces was initiated at a second plant situated at Blochairn. Plates and sections for all aspects of shipbuilding, including boilers, formed the main products; the company also supplied the greater part of the steel for the Forth (Railway) Bridge. Riley was associated with technical modifications which improved the performance of steelmaking furnaces using Siemens's principles. He built a gasfired cupola for melting pig-iron, and constructed the first British "universal" plate mill using three-high rolls (Lauth mill).

At the request of French interests, Riley investigated the properties of steels containing various proportions of nickel; the report that he read before the Iron and Steel Institute in 1889 successfully brought to the notice of potential users the greatly enhanced strength that nickel could impart and its ability to yield alloys possessing substantially lower corrodibility.

The Steel Company of Scotland paid dividends in the years to 1890, but then came a lean period. In 1895, at the age of 54, Riley moved once more to another employer, becoming General Manager of the Glasgow Iron and Steel Company, which had just laid out a new steelmaking plant at Wishaw, 25 km (15 miles) south-east of Glasgow, where it already had blast furnaces. Still the technical innovator, in 1900 Riley presented an account of his experiences in introducing molten blast-furnace metal as feed for the open-hearth steel furnaces. In the early 1890s it was largely through Riley's efforts that a West of Scotland Board of Conciliation and Arbitration for the Manufactured Steel Trade came into being; he was its first Chairman and then its President.

In 1899 James Riley resigned from his Scottish employment to move back to his native Yorkshire, where he became his own master by acquiring the small Richmond Ironworks situated at Stockton-on-Tees. Although Riley's 1900 account to the Iron and Steel Institute was the last of the many of which he was author, he continued to contribute to the discussion of papers written by others.

The son of an engineer, Szilard, after service in the Austro-Hungarian army during the First World War, studied electrical engineering at the University of Berlin. Obtaining his doctorate there in 1922, he joined the faculty and concentrated his studies on thermodynamics. He later began to develop an interest in nuclear physics, and in 1933, shortly after Hitler came to power, Szilard emigrated to Britain because of his Jewish heritage.

In 1934 he conceived the idea of a nuclear chain reaction through the breakdown of beryllium into helium and took out a British patent on it, but later realized that this process would not work. In 1937 he moved to the USA and continued his research at the University of Columbia, and the following year Hahn and Meitner discovered nuclear fission with uranium; this gave Szilard the breakthrough he needed. In 1939 he realized that a nuclear chain reaction could be produced through nuclear fission and that a weapon with many times the destructive power of the conventional high-explosive bomb could be produced. Only too aware of the progress being made by German nuclear scientists, he believed that it was essential that the USA should create an atomic bomb before Hitler. Consequently he drafted a letter to President Roosevelt that summer and, with two fellow Hungarian émigrés, persuaded Albert Einstein to sign it. The result was the setting up of the Uranium Committee.

It was not, however, until December 1941 that active steps began to be taken to produce such a weapon and it was a further nine months before the project was properly co-ordinated under the umbrella of the Manhattan Project. In the meantime, Szilard moved to join Enrico Fermi at the University of Chicago and it was here, at the end of 1942, in a squash court under the football stadium, that they successfully developed the world's first self-sustaining nuclear reactor. Szilard, who became an American citizen in 1943, continued to work on the Manhattan Project. In 1945, however, when the Western Allies began to believe that only the atomic bomb could bring the war against Japan to an end, Szilard and a number of other Manhattan Project scientists objected that it would be immoral to use it against populated targets.

Although he would continue to campaign against nuclear warfare for the rest of his life, Szilard now abandoned nuclear research. In 1946 he became Professor of Biophysics at the University of Chicago and devoted himself to experimental work on bacterial mutations and biochemical mechanisms, as well as theoretical research on ageing and memory.

The son of a baker, his youthful interest in technical affairs led to his being apprenticed to a gunsmith with whom he produced his apprenticeship piece: a double-barrelled pistol with a rifled barrel and "nicely chased scrollwork", for which he received high praise. He remained there until 1852 before going to technical school in Stuttgart from 1853 to 1857. He then went to a steam-engineering company in Strasbourg to gain practical experience. He completed his formal education at Stuttgart Polytechnik, and in 1861 he left to tour France and England. There he worked in the engine-shop of Smith, Peacock \& Tanner and then with Roberts \& Co., textile machinery manufacturers of Manchester. He later moved to Coventry to work at Whitworths, and it was in that city that he was later involved with the Daimler Motor Company, who had been granted a licence by his company in Germany. In 1867 he was working at Bruderhaus Engineering Works at Reutlingen and in 1869 went to Maschinenbau Gesellschaft Karlsruhe where he became Manager and later a director. Early in the 1870s, N.A. Otto had reorganized his company into Gasmotorenfabrik Deutz and he appointed Gottlieb Daimler as Factory Manager and Wilhelm Maybach as Chief Designer. Together they developed the Otto engine to its limit, with Otto's co-operation. Daimler and Maybach had met previously when both were working at Bruderhaus. In 1875 Daimler left Deutz, taking Maybach with him to set up a factory in Stuttgart to manufacture light, high-speed internal-combustion engines. Their first patent was granted in 1883. This was for an engine fuelled by petrol and with hot tube ignition which continued to be used until Robert Bosch's low-voltage ignition became available in 1897. Two years later he produced his first vehicle, a motor cycle with outriggers. They showed a motor car at the Paris exhibition in 1889, but French manufacturers were slow to come forward and no French company could be found to undertake manufacture. Eventually Panhard and Levassor established the Daimler engine in France. Daimler Motoren GmbH was started in 1895, but soon after Daimler and Maybach parted, having provided an engine for a boat on the River Neckar in 1887 and that for the Wolfert airship in 1888. Daimler was in sole charge of the company from 1895, but his health began to decline in 1899 and he died in 1900.

Edwin Reynolds grew up at a time when formal engineering education in America was almost unavailable, but through his genius and his experience working under such masters as G.H. Corliss and William Wright, he developed into one of the best mechanical engineers in the country. When he was Plant Superintendent for the Corliss Steam Engine Company, he built the giant Corliss valve steam engine displayed at the 1876 Centennial Exhibition. In July 1877 he left the Corliss Steam Engine Company to join Edward Allis at his Reliance Works, although he was offered a lower salary. In 1861 Allis had moved his business to the Menomonee Valley, where he had the largest foundry in the area. Immediately on his arrival with Allis, Reynolds began desig-ning and building the "Reliance-Corliss" engine, which becamea symbol of simplicity, economy and reliability. By early 1878 the new engine was so successful that the firm had a six-month backlog of orders. In 1888 he built the first triple-expansion waterworks-pumping engine in the United States for the city of Milwaukee, and in the same year he patented a new design of blowing engine for blast furnaces. He followed this in March 1892 with the first steam engine sets coupled directly to electric generators when Allis-Chalmers contracted to build two Corliss cross-compound engines for the Narragansett Light Company of Providence, Rhode Island. In 1893, one of the impressive attractions at the World's Columbian Exposition in Chicago was the 3,000 hp (2,200 kW) quadruple-expansion Reynolds-Corliss engine designed by Reynolds, who continued to make significant improvements and gained worldwide recognition of his outstanding achievements in engine building.

Reynolds was asked to go to New York in 1898 for consultation about some high-horsepower engines for the Manhattan transport system. There, 225 railway locomotives were to be replaced by electric trains, which would be supplied from one generating station producing 60,000 hp (45,000 kW). Reynolds sketched out his ideas for 10,000 hp (7,500 kW) engines while on the train. Because space was limited, he suggested a four-cylinder design with two horizontal-high-pressure cylinders and two vertical, low-pressure ones. One cylinder of each type was placed on each side of the flywheel generator, which with cranks at 135° gave an exceptionally smooth-running compact engine known as the "Manhattan". A further nine similar engines that were superheated and generated three-phase current were supplied in 1902 to the New York Interborough Rapid Transit Company. These were the largest reciprocating steam engines built for use on land, and a few smaller ones with a similar layout were installed in British textile mills.

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.

The son of a merchant of Dundee, Kirkaldy was educated there, then at Merchiston Castle School, Edinburgh, and at Edinburgh University. For a while he worked in his father's office, but with a preference for engineering, in 1843 he commenced an apprenticeship at the Glasgow works of Robert Napier. After four years in the shops he was transferred to the drawing office and in a very few years rose to become Chief. Here Kirkaldy demonstrated a remarkable talent both for the meticulous recording of observations and data and for technical drawing. His work also had an aesthetic appeal and four of his drawings of Napier steamships were shown at the Paris Exhibition of 1855, earning both Napier and Kirkaldy a medal. His "as fitted" set of drawings of the Cunard Liner Persia, which had been built in 1855, is now in the possession of the National Maritime Museum at Greenwich, London; it is regarded as one of the finest examples of its kind in the world, and has even been exhibited at the Royal Academy in London.

With the impending order for the Royal Naval Ironclad Black Prince (sister ship to HMS Warrior, now preserved at Portsmouth) and for some high-pressure marine boilers and engines, there was need for a close scientific analysis of the physical properties of iron and steel. Kirkaldy, now designated Chief Draughtsman and Calculator, was placed in charge of this work, which included comparisons of puddled steel and wrought iron, using a simple lever-arm testing machine. The tests lasted some three years and resulted in Kirkaldy's most important publication, Experiments on Wrought Iron and Steel (1862, London), which gained him wide recognition for his careful and thorough work. Napier's did not encourage him to continue testing; but realizing the growing importance of materials testing, Kirkaldy resigned from the shipyard in 1861. For the next two and a half years Kirkaldy worked on the design of a massive testing machine that was manufactured in Leeds and installed in premises in London, at The Grove, Southwark.

The works was open for trade in January 1866 and engineers soon began to bring him specimens for testing on the great machine: Joseph Cubitt (son of William Cubitt) brought him samples of the materials for the new Blackfriars Bridge, which was then under construction. Soon The Grove became too cramped and Kirkaldy moved to 99 Southwark Street, reopening in January 1874. In the years that followed, Kirkaldy gained a worldwide reputation for rigorous and meticulous testing and recording of results, coupled with the highest integrity. He numbered the most distinguished engineers of the time among his clients.

After Kirkaldy's death, his son William George, whom he had taken into partnership, carried on the business. When the son died in 1914, his widow took charge until her death in 1938, when the grandson David became proprietor. He sold out to Treharne \& Davies, chemical consultants, in 1965, but the works finally closed in 1974. The future of the premises and the testing machine at first seemed threatened, but that has now been secured and the machine is once more in working order. Over almost one hundred years of trading in South London, the company was involved in many famous enquiries, including the analysis of the iron from the ill-fated Tay Bridge (see Bouch, Sir Thomas).

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.

   Portugal's oldest and once its most prestigious university. As one of Europe's oldest seats of learning, the University of Coimbra and its various roles have a historic importance that supersedes merely the educational. For centuries, the university formed and trained the principal elites and professions that dominated Portugal. For more than a century, certain members of its faculty entered the central government in Lisbon. A few, such as law professor Afonso Costa, mathematics instructor Sidônio Pais, anthropology professor Bernardino Machado, and economics professor Antônio de Oliveira Salazar, became prime ministers and presidents of the republic. In such a small country, with relatively few universities until recently, Portugal counted Coimbra's university as the educational cradle of its leaders and knew its academic traditions as an intimate part of national life.

   Established in 1290 by King Dinis, the university first opened in Lisbon but was moved to Coimbra in 1308, and there it remained. University buildings were placed high on a hill, in a position that

   physically dominates Portugal's third city. While sections of the medieval university buildings are present, much of what today remains of the old University of Coimbra dates from the Manueline era (1495-1521) and the 17th and 18th centuries. The main administration building along the so-called Via Latina is baroque, in the style of the 17th and 18th centuries. Most prominent among buildings adjacent to the central core structures are the Chapel of São Miguel, built in the 17th century, and the magnificent University Library, of the era of wealthy King João V, built between 1717 and 1723. Created entirely by Portuguese artists and architects, the library is unique among historic monuments in Portugal. Its rare book collection, a monument in itself, is complemented by exquisite gilt wood decorations and beautiful doors, windows, and furniture. Among visitors and tourists, the chapel and library are the prime attractions to this day.

   The University underwent important reforms under the Pombaline administration (1750-77). Efforts to strengthen Coimbra's position in advanced learning and teaching by means of a new curriculum, including new courses in new fields and new degrees and colleges (in Portugal, major university divisions are usually called "faculties") often met strong resistance. In the Age of the Discoveries, efforts were made to introduce the useful study of mathematics, which was part of astronomy in that day, and to move beyond traditional medieval study only of theology, canon law, civil law, and medicine. Regarding even the advanced work of the Portuguese astronomer and mathematician Pedro Nunes, however, Coimbra University was lamentably slow in introducing mathematics or a school of arts and general studies. After some earlier efforts, the 1772 Pombaline Statutes, the core of the Pombaline reforms at Coimbra, had an impact that lasted more than a century. These reforms remained in effect to the end of the monarchy, when, in 1911, the First Republic instituted changes that stressed the secularization of learning. This included the abolition of the Faculty of Theology.

   Elaborate, ancient traditions and customs inform the faculty and student body of Coimbra University. Tradition flourishes, although some customs are more popular than others. Instead of residing in common residences or dormitories as in other countries, in Coimbra until recently students lived in the city in "Republics," private houses with domestic help hired by the students. Students wore typical black academic gowns. Efforts during the Revolution of 25 April 1974 and aftermath to abolish the wearing of the gowns, a powerful student image symbol, met resistance and generated controversy. In romantic Coimbra tradition, students with guitars sang characteristic songs, including Coimbra fado, a more cheerful song than Lisbon fado, and serenaded other students at special locations. Tradition also decreed that at graduation graduates wore their gowns but burned their school (or college or subject) ribbons ( fitas), an important ceremonial rite of passage.

   The University of Coimbra, while it underwent a revival in the 1980s and 1990s, no longer has a virtual monopoly over higher education in Portugal. By 1970, for example, the country had only four public and one private university, and the University of Lisbon had become more significant than ancient Coimbra. At present, diversity in higher education is even more pronounced: 12 private universities and 14 autonomous public universities are listed, not only in Lisbon and Oporto, but at provincial locations. Still, Coimbra retains an influence as the senior university, some of whose graduates still enter national government and distinguished themselves in various professions.

   An important student concern at all institutions of higher learning, and one that marked the last half of the 1990s and continued into the next century, was the question of increased student fees and tuition payments (in Portuguese, propinas). Due to the expansion of the national universities in function as well as in the size of student bodies, national budget constraints, and the rising cost of education, the central government began to increase student fees. The student movement protested this change by means of various tactics, including student strikes, boycotts, and demonstrations. At the same time, a growing number of private universities began to attract larger numbers of students who could afford the higher fees in private institutions, but who had been denied places in the increasingly competitive and pressured public universities.

   In Portugal's early history, education was firmly under the control of the Catholic Church. The earliest schools were located in cathedrals and monasteries and taught a small number of individuals destined for ecclesiastical office. In 1290, a university was established by King Dinis (1261-1325) in Lisbon, but was moved to Coimbra in 1308, where it remained. Coimbra University, Portugal's oldest, and once its most prestigious, was the educational cradle of Portugal's leadership. From 1555 until the 18th century, primary and secondary education was provided by the Society of Jesus (Jesuits). The Catholic Church's educational monopoly was broken when the Marquis of Pombal expelled the Jesuits in 1759 and created the basis for Portugal's present system of public, secular primary and secondary schools. Pombal introduced vocational training, created hundreds of teaching posts, added departments of mathematics and natural sciences at Coimbra University, and established an education tax to pay for them.

   During the 19th century, liberals attempted to reform Portugal's educational system, which was highly elitist and emphasized rote memorization and respect for authority, hierarchy, and discipline.

   Reforms initiated in 1822, 1835, and 1844 were never actualized, however, and education remained unchanged until the early 20th century. After the overthrow of the monarchy on the Fifth of October 1910 by Republican military officers, efforts to reform Portugal's educational system were renewed. New universities were founded in Lisbon and Oporto, a Ministry of Education was established, and efforts were made to increase literacy (illiteracy rates being 80 percent) and to resecularize educational content by introducing more scientific and empirical methods into the curriculum.

   Such efforts were ended during the military dictatorship (192632), which governed Portugal until the establishment of the Estado Novo (1926-74). Although a new technical university was founded in Lisbon in 1930, little was done during the Estado Novo to modernize education or to reduce illiteracy. Only in 1964 was compulsory primary education made available for children between the ages of 6 and 12.

   The Revolution of 25 April 1974 disrupted Portugal's educational system. For a period of time after the Revolution, students, faculty, and administrators became highly politicized as socialists, communists, and other groups attempted to gain control of the schools. During the 1980s, as Portuguese politics moderated, the educational system was gradually depoliticized, greater emphasis was placed on learning, and efforts were made to improve the quality of Portuguese schools.

   Primary education in Portugal consists of four years in the primary (first) cycle and two years in the preparatory, or second, cycle. The preparatory cycle is intended for children going on to secondary education. Secondary education is roughly equivalent to junior and senior high schools in the United States. It consists of three years of a common curriculum and two years of complementary courses (10th and 11th grades). A final year (12th grade) prepares students to take university entrance examinations.

   Vocational education was introduced in 1983. It consists of a three-year course in a particular skill after the 11th grade of secondary school.

   Higher education is provided by the four older universities (Lisbon, Coimbra, Oporto, and the Technical University of Lisbon), as well as by six newer universities, one in Lisbon and the others in Minho, Aveiro, Évora, the Algarve, and the Azores. There is also a private Catholic university in Lisbon. Admission to Portuguese universities is highly competitive, and places are limited. About 10 percent of secondary students go on to university education. The average length of study at the university is five years, after which students receive their licentiate. The professoriate has four ranks (professors, associate professors, lecturers, and assistants). Professors have tenure, while the other ranks teach on contract.

   As Portugal is a unitary state, the educational system is highly centralized. All public primary and secondary schools, universities, and educational institutes are under the purview of the Ministry of Education, and all teachers and professors are included in the civil service and receive pay and pension like other civil servants. The Ministry of Education hires teachers, determines curriculum, sets policy, and pays for the building and upkeep of schools. Local communities have little say in educational matters.

Born into a poor family in the Bronx, New York City, Berezin first majored in business studies but transferred her interest to physics. She graduated in 1946 and then, with the aid of an Atomic Energy Commission fellowship, she obtained her PhD in cosmic ray physics at New York University. When the fellowship expired, opportunities in the developing field of electronic data processing seemed more promising than thise in physics. Berezin entered the firm of Electronic Computer Corporation in 1951 and was asked to "build a computer", although few at that time had actually seen one; the result was the Elecom 200. In 1953, for Underwood Corporation, she designed the first office computer, although it was never marketed, as Underwood sold out to Olivetti.

Berezin's next position was as head of logic design for Teleregister Corporation in the late 1950s. Here, she led a team specializing in the design of on-line systems. Her most notable achievement was the design of a nationwide online computer reservation system for United Airlines, the first system of this kind and the precursor of similar on-line systems. It was installed in the early 1960s and was the first large non-military on-line interactive system.

In the 1960s Berezin moved to the Digitronics Corporation as manager of logic design, her work here resulted in the first high-speed commercial digital communications terminal. Also in the 1960s, her involvement in Data Secretary, a challenger to the IBM editing typewriter, makes it possible to regard her as one of the pioneers of word processing. In 1976 Berezin transferred from the electronic data and computing field to that of financial management.

The Brennan family, including Louis, emigrated to Australia in 1861. He was an inventive genius from childhood, and while at Melbourne invented his torpedo. Within it were two drums, each with several miles of steel wire coiled upon it and mounted on one of two concentric propeller shafts. The propellers revolved in opposite directions. Wires were led out of the torpedo to winding drums on land, driven by high-speed steam engines: the faster the drums on shore were driven, the quicker the wires were withdrawn from the drums within the torpedo and the quicker the propellers turned. A steering device was operated by altering the speeds of the wires relative to one another. As finally developed, Brennan torpedoes were accurate over a range of 1 1/2 miles (2.4 km), in contrast to contemporary self-propelled torpedoes, which were unreliable at ranges over 400 yards (366 in).

Brennan moved to England in 1880 and sold the rights to his torpedo to the British Government for a total of £110,000, probably the highest payment ever made by it to an individual inventor. Brennan torpedoes became part of the defences of many vital naval ports, but never saw active service: improvement of other means of defence meant they were withdrawn in 1906. By then Brennan was deeply involved in the development of his monorail. The need for a simple and cheap form of railway had been apparent to him when in Australia and he considered it could be met by a ground-level monorail upon which vehicles would be balanced by gyroscopes. After overcoming many manufacturing difficulties, he demonstrated first a one-eighth scale version and then a full-size, electrically driven vehicle, which ran on its single rail throughout the summer of 1910 in London, carrying up to fifty passengers at a time. Development had been supported financially by, successively, the War Office, the India Office and the Government of the Indian state of Jammu and Kashmir, which had no rail access; despite all this, however, no further financial support, government or commercial, was forthcoming.

Brennan made many other inventions, worked on the early development of helicopters and in 1929 built a gyroscopically balanced, two-wheeled motor car which, however, never went into production.

Born Elinor Coade, she never married but adopted, as was customary in business in the eighteenth century, the courtesy title of Mrs. Following the bankruptcy and death of her father, George Coade, in Exeter, Eleanor and her mother (also called Eleanor) moved to London and founded the works at Lambeth, South London, in 1769 that later became famous as the Coade factory. The factory was located at King's Arms Stairs, Narrow Wall. During the eighteenth century, several attempts had been made in other businesses to manufacture a durable, malleable artificial stone that would be acceptable to architects for decorative use. These substances were not very successful, but Coade stone was different. Although stories are legion about the secret formula supposedly used in this artificial stone, modern methods have established the exact formula.

Coade stone was a stoneware ceramic material fired in a kiln. The body was remarkable in that it shrank only 8 per cent in drying and firing: this was achieved by using a combination of china clay, sand, crushed glass and grog (i.e. crushed and ground, previously fired stoneware). The Coade formula thus included a considerable proportion of material that, having been fired once already, was unshrinkable. Mrs Coade's name for the firm, Coade's Lithodipyra Terra-Cotta or Artificial Stone Manufactory (where "Lithodipyra" is a term derived from three Greek words meaning "stone", "twice" and "fire"), made reference to the custom of including such material (such as in Josiah Wedgwood's basalt and jasper ware). The especially low rate of shrinkage rendered the material ideal for making extra-life-size statuary, and large architectural, decorative features to be incorporated into stone buildings.

Coade stone was widely used for such purposes by leading architects in Britain and Ireland from the 1770s until the 1830s, including Robert Adam, Sir Charles Barry, Sir William Chambers, Sir John Soane, John Nash and James Wyatt. Some architects introduced the material abroad, as far as, for example, Charles Bulfinch's United States Bank in Boston, Massachusetts, and Charles Cameron's redecoration for the Empress Catherine of the great palace Tsarkoe Selo (now Pushkin), near St Petersburg. The material so resembles stone that it is often mistaken for it, but it is so hard and resistant to weather that it retains sharpness of detail much longer than the natural substance. The many famous British buildings where Coade stone was used include the Royal Hospital, Chelsea, Carlton House and the Sir John Soane Museum (all of which are located in London), St George's Chapel at Windsor, Alnwick Castle in Northumberland, and Culzean Castle in Ayrshire, Scotland.

Apart from the qualities of the material, the Coade firm established a high reputation for the equally fine quality of its classical statuary. Mrs Coade employed excellent craftsmen such as the sculptor John Bacon (1740–99), whose work was mass-produced by the use of moulds. One famous example which was widely reproduced was the female caryatid from the south porch of the Erechtheion on the acropolis of Athens. A drawing of this had appeared in the second edition of Stuart and Revett's Antiquities of Athens in 1789, and many copies were made from the original Coade model; Soane used them more than once, for example on the Bank of England and his own houses in London.

Eleanor Coade was a remarkable woman, and was important and influential on the neo-classical scene. She had close and amicable relations with leading architects of the day, notably Robert Adam and James Wyatt. The Coade factory was enlarged and altered over the years, but the site was finally cleared during 1949–50 in preparation for the establishment of the 1951 Festival of Britain.

When Arthur Woolf left the Griffin Brewery, London, in October 1808, he formed a partnership with Humphrey Edwards, described as a millwright at Mill Street, Lambeth, where they started an engine works to build Woolf's type of compound engine. A number of small engines were constructed and other ordinary engines modified with the addition of a high-pressure cylinder. Improvements were made in each succeeding engine, and by 1811 a standard form had been evolved. During this experimental period, engines were made with cylinders side by side as well as the more usual layout with one behind the other. The valve gear and other details were also improved. Steam pressure may have been around 40 psi (2.8 kg/cm²). In an advertisement of February 1811, the partners claimed that their engines had been brought to such a state of perfection that they consumed only half the quantity of coal required for engines on the plan of Messrs Boulton \& Watt. Woolf visited Cornwall, where he realized that more potential for his engines lay there than in London; in May 1811 the partnership was dissolved, with Woolf returning to his home county. Edwards struggled on alone in London for a while, but when he saw a more promising future for the engine in France he moved to Paris. On 25 May 1815 he obtained a French patent, a Brevet d'importation, for ten years. A report in 1817 shows that during the previous two years he had imported into France fifteen engines of different sizes which were at work in eight places in various parts of the country. He licensed a mining company in the north of France to make twenty-five engines for winding coal. In France there was always much more interest in rotative engines than pumping ones. Edwards may have formed a partnership with Goupil \& Cie, Dampierre, to build engines, but this is uncertain. He became a member of the firm Scipion, Perrier, Edwards \& Chappert, which took over the Chaillot Foundry of the Perrier Frères in Paris, and it seems that Edwards continued to build steam engines there for the rest of his life. In 1824 it was claimed that he had made about 100 engines in England and another 200 in France, but this is probably an exaggeration.

The Woolf engine acquired its popularity in France because its compound design was more economical than the single-cylinder type. To enable it to be operated safely, Edwards first modified Woolf s cast-iron boiler in 1815 by placing two small drums over the fire, and then in 1825 replaced the cast iron with wrought iron. The modified boiler was eventually brought back to England in the 1850s as the "French" or "elephant" boiler.
