He was the son of an Irish immigrant farmer, William Ford, and the oldest son to survive of Mary Litogot; his mother died in 1876 with the birth of her sixth child. He went to the village school, and at the age of 16 he was apprenticed to Flower brothers' machine shop and then at the Drydock \& Engineering Works in Detroit. In 1882 he left to return to the family farm and spent some time working with a 1 1/2 hp steam engine doing odd jobs for the farming community at $3 per day. He was then employed as a demonstrator for Westinghouse steam engines. He met Clara Jane Bryant at New Year 1885 and they were married on 11 April 1888. Their only child, Edsel Bryant Ford, was born on 6 November 1893.

At that time Henry worked on steam engine repairs for the Edison Illuminating Company, where he became Chief Engineer. He became one of a group working to develop a "horseless carriage" in 1896 and in June completed his first vehicle, a "quadri cycle" with a two-cylinder engine. It was built in a brick shed, which had to be partially demolished to get the carriage out.

Ford became involved in motor racing, at which he was more successful than he was in starting a car-manufacturing company. Several early ventures failed, until the Ford Motor Company of 1903. By October 1908 they had started with production of the Model T. The first, of which over 15 million were built up to the end of its production in May 1927, came out with bought-out steel stampings and a planetary gearbox, and had a one-piece four-cylinder block with a bolt-on head. This was one of the most successful models built by Ford or any other motor manufacturer in the life of the motor car.

Interchangeability of components was an important element in Ford's philosophy. Ford was a pioneer in the use of vanadium steel for engine components. He adopted the principles of Frederick Taylor, the pioneer of time-and-motion study, and installed the world's first moving assembly line for the production of magnetos, started in 1913. He installed blast furnaces at the factory to make his own steel, and he also promoted research and the cultivation of the soya bean, from which a plastic was derived.

In October 1913 he introduced the "Five Dollar Day", almost doubling the normal rate of pay. This was a profit-sharing scheme for his employees and contained an element of a reward for good behaviour. About this time he initiated work on an agricultural tractor, the "Fordson" made by a separate company, the directors of which were Henry and his son Edsel.

In 1915 he chartered the Oscar II, a "peace ship", and with fifty-five delegates sailed for Europe a week before Christmas, docking at Oslo. Their objective was to appeal to all European Heads of State to stop the war. He had hoped to persuade manufacturers to replace armaments with tractors in their production programmes. In the event, Ford took to his bed in the hotel with a chill, stayed there for five days and then sailed for New York and home. He did, however, continue to finance the peace activists who remained in Europe. Back in America, he stood for election to the US Senate but was defeated. He was probably the father of John Dahlinger, illegitimate son of Evangeline Dahlinger, a stenographer employed by the firm and on whom he lavished gifts of cars, clothes and properties. He became the owner of a weekly newspaper, the Dearborn Independent, which became the medium for the expression of many of his more unorthodox ideas. He was involved in a lawsuit with the Chicago Tribune in 1919, during which he was cross-examined on his knowledge of American history: he is reputed to have said "History is bunk". What he actually said was, "History is bunk as it is taught in schools", a very different comment. The lawyers who thus made a fool of him would have been surprised if they could have foreseen the force and energy that their actions were to release. For years Ford employed a team of specialists to scour America and Europe for furniture, artefacts and relics of all kinds, illustrating various aspects of history. Starting with the Wayside Inn from South Sudbury, Massachusetts, buildings were bought, dismantled and moved, to be reconstructed in Greenfield Village, near Dearborn. The courthouse where Abraham Lincoln had practised law and the Ohio bicycle shop where the Wright brothers built their first primitive aeroplane were added to the farmhouse where the proprietor, Henry Ford, had been born. Replicas were made of Independence Hall, Congress Hall and the old City Hall in Philadelphia, and even a reconstruction of Edison's Menlo Park laboratory was installed. The Henry Ford museum was officially opened on 21 October 1929, on the fiftieth anniversary of Edison's invention of the incandescent bulb, but it continued to be a primary preoccupation of the great American car maker until his death.

Henry Ford was also responsible for a number of aeronautical developments at the Ford Airport at Dearborn. He introduced the first use of radio to guide a commercial aircraft, the first regular airmail service in the United States. He also manufactured the country's first all-metal multi-engined plane, the Ford Tri-Motor.

Edsel became President of the Ford Motor Company on his father's resignation from that position on 30 December 1918. Following the end of production in May 1927 of the Model T, the replacement Model A was not in production for another six months. During this period Henry Ford, though officially retired from the presidency of the company, repeatedly interfered and countermanded the orders of his son, ostensibly the man in charge. Edsel, who died of stomach cancer at his home at Grosse Point, Detroit, on 26 May 1943, was the father of Henry Ford II. Henry Ford died at his home, "Fair Lane", four years after his son's death.

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.

(1889-1970)

   The Coimbra University professor of finance and economics and one of the founders of the Estado Novo, who came to dominate Western Europe's longest surviving authoritarian system. Salazar was born on 28 April 1889, in Vimieiro, Beira Alta province, the son of a peasant estate manager and a shopkeeper. Most of his first 39 years were spent as a student, and later as a teacher in a secondary school and a professor at Coimbra University's law school. Nine formative years were spent at Viseu's Catholic Seminary (1900-09), preparing for the Catholic priesthood, but the serious, studious Salazar decided to enter Coimbra University instead in 1910, the year the Braganza monarchy was overthrown and replaced by the First Republic. Salazar received some of the highest marks of his generation of students and, in 1918, was awarded a doctoral degree in finance and economics. Pleading inexperience, Salazar rejected an invitation in August 1918 to become finance minister in the "New Republic" government of President Sidónio Pais.

   As a celebrated academic who was deeply involved in Coimbra University politics, publishing works on the troubled finances of the besieged First Republic, and a leader of Catholic organizations, Sala-zar was not as modest, reclusive, or unknown as later official propaganda led the public to believe. In 1921, as a Catholic deputy, he briefly served in the First Republic's turbulent congress (parliament) but resigned shortly after witnessing but one stormy session. Salazar taught at Coimbra University as of 1916, and continued teaching until April 1928. When the military overthrew the First Republic in May 1926, Salazar was offered the Ministry of Finance and held office for several days. The ascetic academic, however, resigned his post when he discovered the degree of disorder in Lisbon's government and when his demands for budget authority were rejected.

   As the military dictatorship failed to reform finances in the following years, Salazar was reinvited to become minister of finances in April 1928. Since his conditions for acceptance—authority over all budget expenditures, among other powers—were accepted, Salazar entered the government. Using the Ministry of Finance as a power base, following several years of successful financial reforms, Salazar was named interim minister of colonies (1930) and soon garnered sufficient prestige and authority to become head of the entire government. In July 1932, Salazar was named prime minister, the first civilian to hold that post since the 1926 military coup.

   Salazar gathered around him a team of largely academic experts in the cabinet during the period 1930-33. His government featured several key policies: Portuguese nationalism, colonialism (rebuilding an empire in shambles), Catholicism, and conservative fiscal management. Salazar's government came to be called the Estado Novo. It went through three basic phases during Salazar's long tenure in office, and Salazar's role underwent changes as well. In the early years (1928-44), Salazar and the Estado Novo enjoyed greater vigor and popularity than later. During the middle years (1944—58), the regime's popularity waned, methods of repression increased and hardened, and Salazar grew more dogmatic in his policies and ways. During the late years (1958-68), the regime experienced its most serious colonial problems, ruling circles—including Salazar—aged and increasingly failed, and opposition burgeoned and grew bolder.

   Salazar's plans for stabilizing the economy and strengthening social and financial programs were shaken with the impact of the civil war (1936-39) in neighboring Spain. Salazar strongly supported General Francisco Franco's Nationalist rebels, the eventual victors in the war. But, as the civil war ended and World War II began in September 1939, Salazar's domestic plans had to be adjusted. As Salazar came to monopolize Lisbon's power and authority—indeed to embody the Estado Novo itself—during crises that threatened the future of the regime, he assumed ever more key cabinet posts. At various times between 1936 and 1944, he took over the Ministries of Foreign Affairs and of War (Defense), until the crises passed. At the end of the exhausting period of World War II, there were rumors that the former professor would resign from government and return to Coimbra University, but Salazar continued as the increasingly isolated, dominating "recluse of São Bento," that part of the parliament's buildings housing the prime minister's offices and residence.

   Salazar dominated the Estado Novo's government in several ways: in day-to-day governance, although this diminished as he delegated wider powers to others after 1944, and in long-range policy decisions, as well as in the spirit and image of the system. He also launched and dominated the single party, the União Nacional. A lifelong bachelor who had once stated that he could not leave for Lisbon because he had to care for his aged mother, Salazar never married, but lived with a beloved housekeeper from his Coimbra years and two adopted daughters. During his 36-year tenure as prime minister, Salazar engineered the important cabinet reshuffles that reflect the history of the Estado Novo and of Portugal.

   A number of times, in connection with significant events, Salazar decided on important cabinet officer changes: 11 April 1933 (the adoption of the Estado Novo's new 1933 Constitution); 18 January 1936 (the approach of civil war in Spain and the growing threat of international intervention in Iberian affairs during the unstable Second Spanish Republic of 1931-36); 4 September 1944 (the Allied invasion of Europe at Normandy and the increasing likelihood of a defeat of the Fascists by the Allies, which included the Soviet Union); 14 August 1958 (increased domestic dissent and opposition following the May-June 1958 presidential elections in which oppositionist and former regime stalwart-loyalist General Humberto Delgado garnered at least 25 percent of the national vote, but lost to regime candidate, Admiral Américo Tomás); 13 April 1961 (following the shock of anticolonial African insurgency in Portugal's colony of Angola in January-February 1961, the oppositionist hijacking of a Portuguese ocean liner off South America by Henrique Galvão, and an abortive military coup that failed to oust Salazar from office); and 19 August 1968 (the aging of key leaders in the government, including the now gravely ill Salazar, and the defection of key younger followers).

   In response to the 1961 crisis in Africa and to threats to Portuguese India from the Indian government, Salazar assumed the post of minister of defense (April 1961-December 1962). The failing leader, whose true state of health was kept from the public for as long as possible, appointed a group of younger cabinet officers in the 1960s, but no likely successors were groomed to take his place. Two of the older generation, Teotónio Pereira, who was in bad health, and Marcello Caetano, who preferred to remain at the University of Lisbon or in private law practice, remained in the political wilderness.

   As the colonial wars in three African territories grew more costly, Salazar became more isolated from reality. On 3 August 1968, while resting at his summer residence, the Fortress of São João do Estoril outside Lisbon, a deck chair collapsed beneath Salazar and his head struck the hard floor. Some weeks later, as a result, Salazar was incapacitated by a stroke and cerebral hemorrhage, was hospitalized, and became an invalid. While hesitating to fill the power vacuum that had unexpectedly appeared, President Tomás finally replaced Salazar as prime minister on 27 September 1968, with his former protégé and colleague, Marcello Caetano. Salazar was not informed that he no longer headed the government, but he never recovered his health. On 27 July 1970, Salazar died in Lisbon and was buried at Santa Comba Dão, Vimieiro, his village and place of birth.

Samuel Crompton was the son of a tenant farmer, George, who became the caretaker of the old house Hall-i-th-Wood, near Bolton, where he died in 1759. As a boy, Samuel helped his widowed mother in various tasks at home, including weaving. He liked music and made his own violin, with which he later was to earn some money to pay for tools for building his spinning mule. He was set to work at spinning and so in 1769 became familiar with the spinning jenny designed by James Hargreaves; he soon noticed the poor quality of the yarn produced and its tendency to break. Crompton became so exasperated with the jenny that in 1772 he decided to improve it. After seven years' work, in 1779 he produced his famous spinning "mule". He built the first one entirely by himself, principally from wood. He adapted rollers similar to those already patented by Arkwright for drawing out the cotton rovings, but it seems that he did not know of Arkwright's invention. The rollers were placed at the back of the mule and paid out the fibres to the spindles, which were mounted on a moving carriage that was drawn away from the rollers as the yarn was paid out. The spindles were rotated to put in twist. At the end of the draw, or shortly before, the rollers were stopped but the spindles continued to rotate. This not only twisted the yarn further, but slightly stretched it and so helped to even out any irregularities; it was this feature that gave the mule yarn extra quality. Then, after the spindles had been turned backwards to unwind the yarn from their tips, they were rotated in the spinning direction again and the yarn was wound on as the carriage was pushed up to the rollers.

The mule was a very versatile machine, making it possible to spin almost every type of yarn. In fact, Samuel Crompton was soon producing yarn of a much finer quality than had ever been spun in Bolton, and people attempted to break into Hall-i-th-Wood to see how he produced it. Crompton did not patent his invention, perhaps because it consisted basically of the essential features of the earlier machines of Hargreaves and Arkwright, or perhaps through lack of funds. Under promise of a generous subscription, he disclosed his invention to the spinning industry, but was shabbily treated because most of the promised money was never paid. Crompton's first mule had forty-eight spindles, but it did not long remain in its original form for many people started to make improvements to it. The mule soon became more popular than Arkwright's waterframe because it could spin such fine yarn, which enabled weavers to produce the best muslin cloth, rivalling that woven in India and leading to an enormous expansion in the British cotton-textile industry. Crompton eventually saved enough capital to set up as a manufacturer himself and around 1784 he experimented with an improved carding engine, although he was not successful. In 1800, local manufacturers raised a sum of £500 for him, and eventually in 1812 he received a government grant of £5,000, but this was trifling in relation to the immense financial benefits his invention had conferred on the industry, to say nothing of his expenses. When Crompton was seeking evidence in 1811 to support his claim for financial assistance, he found that there were 4,209,570 mule spindles compared with 155,880 jenny and 310,516 waterframe spindles. He later set up as a bleacher and again as a cotton manufacturer, but only the gift of a small annuity by his friends saved him from dying in total poverty.

Dickson was born in France of English and Scottish parents. As a young man of almost 19 years, he wrote in 1879 to Thomas Edison in America, asking for a job. Edison replied that he was not taking on new staff at that time, but Dickson, with his mother and sisters, decided to emigrate anyway. In 1883 he contacted Edison again, and was given a job at the Goerk Street laboratory of the Edison Electric Works in New York. He soon assumed a position of responsibility as Superintendent, working on the development of electric light and power systems, and also carried out most of the photography Edison required. In 1888 he moved to the Edison West Orange laboratory, becoming Head of the ore-milling department. When Edison, inspired by Muybridge's sequence photographs of humans and animals in motion, decided to develop a motion picture apparatus, he gave the task to Dickson, whose considerable skills in mechanics, photography and electrical work made him the obvious choice. The first experiments, in 1888, were on a cylinder machine like the phonograph, in which the sequence pictures were to be taken in a spiral. This soon proved to be impractical, and work was delayed for a time while Dickson developed a new ore-milling machine. Little progress with the movie project was made until George Eastman's introduction in July 1889 of celluloid roll film, which was thin, tough, transparent and very flexible. Dickson returned to his experiments in the spring of 1891 and soon had working models of a film camera and viewer, the latter being demonstrated at the West Orange laboratory on 20 May 1891. By the early summer of 1892 the project had advanced sufficiently for commercial exploitation to begin. The Kinetograph camera used perforated 35 mm film (essentially the same as that still in use in the late twentieth century), and the kinetoscope, a peep-show viewer, took fifty feet of film running in an endless loop. Full-scale manufacture of the viewers started in 1893, and they were demonstrated on a number of occasions during that year. On 14 April 1894 the first kinetoscope parlour, with ten viewers, was opened to the public in New York. By the end of that year, the kinetoscope was seen by the public all over America and in Europe. Dickson had created the first commercially successful cinematograph system. Dickson left Edison's employment on 2 April 1895, and for a time worked with Woodville Latham on the development of his Panoptikon projector, a projection version of the kinetoscope. In December 1895 he joined with Herman Casier, Henry N.Marvin and Elias Koopman to form the American Mutoscope Company. Casier had designed the Mutoscope, an animated-picture viewer in which the sequences of pictures were printed on cards fixed radially to a drum and were flipped past the eye as the drum rotated. Dickson designed the Biograph wide-film camera to produce the picture sequences, and also a projector to show the films directly onto a screen. The large-format images gave pictures of high quality for the period; the Biograph went on public show in America in September 1896, and subsequently throughout the world, operating until around 1905. In May 1897 Dickson returned to England and set up as a producer of Biograph films, recording, among other subjects, Queen Victoria's Diamond Jubilee celebrations in 1897, Pope Leo XIII in 1898, and scenes of the Boer War in 1899 and 1900. Many of the Biograph subjects were printed as reels for the Mutoscope to produce the "what the butler saw" machines which were a feature of fairgrounds and seaside arcades until modern times. Dickson's contact with the Biograph Company, and with it his involvement in cinematography, ceased in 1911.

   Traditionally and for a half millennium, Portugal has been a country of emigration, but in recent decades it has become a country of net immigration. During Portugal's long period of overseas empire, beginning in the 15th century, there was always more emigration overseas than immigration to Portugal. There were, nevertheless, populations of natives of Africa, Asia, and the Americas who came to Portugal during the 1450-1975 era. Historians continue to debate the actual numbers of migrants of African descent to Portugal during this period, but records suggest that the resident African population in Portugal during the 16th, 17th, and 18th centuries was a minority of some consequence but not as large as previously imagined.

   After the wars of independence in Africa began in 1961, and after India conquered and annexed former Portuguese Goa, Damão, and Diu in December of that year, Portugal began to receive more migrants from Asia and Africa than before. First came political refugees carrying Portuguese passports from former Portuguese India; these left India for Portugal in the early 1960s. But the larger numbers came from Portugal's former colonial territories in Africa, especially from Angola, Mozambique, and Guinea-Bissau; these sought refuge from civil wars and conflicts following the end of the colonial wars and independence from Portugal. While a considerable number of the refugee wave of 1975-76 from these territories were of African as well as Afro-European descent, larger numbers of African migrants began to arrive in the 1980s. A major impetus for their migration to Portugal was to escape civil wars in Angola and Mozambique.

   Another wave of migrants of European descent came beginning in the 1990s, primarily from Ukraine, Russia, Rumania, and Moldova. Following the fall of the Berlin Wall in November 1989, and the implosion of the Soviet Union, migrants from these countries arrived in Portugal in some number. At about the same time, there arrived migrants from Brazil and another former colony of Portugal, the isolated, poverty-stricken Cape Verde Islands. The largest number of foreign immigrants in Portugal continue to be the Brazilians and the Cape Verdeans, whose principal language is also Portuguese.

   Different ethnic migrant groups tended to work in certain occupations; for example, Brazilians were largely professional people, including dentists and technicians. Cape Verdeans, by and large, as well as numbers of other African migrants from former Portuguese African territories, worked in the construction industry or in restaurants and hotels. As of 2004, the non- European Union (EU) migrant population was over 374,000, while the EU migrant numbers were about 74,000.

   Of the foreign migrants from EU countries, the largest community was the British, with as many as 20,000 residents, with smaller numbers from France, Germany, Italy, and Spain. About 9,000 Americans reside in Portugal. Unlike many migrants from the non-EU countries noted above, who sought safety and a way to make a decent living, migrants from Europe and the United States include many who seek a comfortable retirement in Portugal, with its warm, sunny climate, fine cuisine, and security.

John Arnold was apprenticed to his father, a watchmaker, and then worked as an itinerant journeyman in the Low Countries and, later, in England. He settled in London in 1762 and rapidly established his reputation at Court by presenting George III with a miniature repeating watch mounted in a ring. He later abandoned the security of the Court for a more precarious living developing his chronometers, with some financial assistance from the Board of Longitude. Symbolically, in 1771 he moved from the vicinity of the Court at St James's to John Adam Street, which was close to the premises of the Royal Society for the Encouragement of Arts, Manufactures \& Commerce.

By the time Arnold became interested in chronometry, Harrison had already demonstrated that longitude could be determined by means of a timekeeper, and the need was for a simpler instrument that could be sold at an affordable price for universal use at sea. Le Roy had shown that it was possible to dispense with a remontoire by using a detached escapement with an isochronous balance; Arnold was obviously thinking along the same lines, although he may not have been aware of Le Roy's work. By 1772 Arnold had developed his detached escapement, a pivoted detent which was quite different from that used on the European continent, and three years later he took out a patent for a compensation balance and a helical balance spring (Arnold used the spring in torsion and not in tension as Harrison had done). His compensation balance was similar in principle to that described by Le Roy and used riveted bimetallic strips to alter the radius of gyration of the balance by moving small weights radially. Although the helical balance spring was not completely isochronous it was a great improvement on the spiral spring, and in a later patent (1782) he showed how it could be made more truly isochronous by shaping the ends. In this form it was used universally in marine chronometers.

Although Arnold's chronometers performed well, their long-term stability was less satisfactory because of the deterioration of the oil on the pivot of the detent. In his patent of 1782 he eliminated this defect by replacing the pivot with a spring, producing the spring detent escapement. This was also done independendy at about the same time by Berthoud and Earnshaw, although Earnshaw claimed vehemently that Arnold had plagiarized his work. Ironically it was Earnshaw's design that was finally adopted, although he had merely replaced Arnold's pivoted detent with a spring, while Arnold had completely redesigned the escapement. Earnshaw also improved the compensation balance by fusing the steel to the brass to form the bimetallic element, and it was in this form that it began to be used universally for chronometers and high-grade watches.

As a result of the efforts of Arnold and Earnshaw, the marine chronometer emerged in what was essentially its final form by the end of the eighteenth century. The standardization of the design in England enabled it to be produced economically; whereas Larcum Kendall was paid £500 to copy Harrison's fourth timekeeper, Arnold was able to sell his chronometers for less than one-fifth of that amount. This combination of price and quality led to Britain's domination of the chronometer market during the nineteenth century.

After receiving his education at Eton and Trinity College, Cambridge, Bacon served with C.A. Parsons at Newcastle upon Tyne from 1925 to 1940. From 1946 to 1956 he carried out research on Hydrox fuel cells at Cambridge University and was a consultant on fuel-cell design to a number of organizations throughout the rest of his life.

Sir William Grove was the first to observe that when oxygen and hydrogen were supplied to platinum electrodes immersed in sulphuric acid a current was produced in an external circuit, but he did not envisage this as a practical source of electrical energy. In the 1930s Bacon started work to develop a hydrogen-oxygen fuel cell that operated at moderate temperatures and pressures using an alkaline electrolyte. In 1940 he was appointed to a post at King's College, London, and there, with the support of the Admiralty, he started full-time experimental work on fuel cells. His brief was to produce a power source for the propulsion of submarines. The following year he was posted as a temporary experimental officer to the Anti-Submarine Experimental Establishment at Fairlie, Ayrshire, and he remained there until the end of the Second World War.

In 1946 he joined the Department of Chemical Engineering at Cambridge, receiving a small amount of money from the Electrical Research Association. Backing came six years later from the National Research and Development Corporation (NRDC), the development of the fuel cell being transferred to Marshalls of Cambridge, where Bacon was appointed Consultant.

By 1959, after almost twenty years of individual effort, he was able to demonstrate a 6 kW (8 hp) power unit capable of driving a small truck. Bacon appreciated that when substantial power was required over long periods the hydrogen-oxygen fuel cell associated with high-pressure gas storage would be more compact than conventional secondary batteries.

The development of the fuel-cell system pioneered by Bacon was stimulated by a particular need for a compact, lightweight source of power in the United States space programme. Electro-chemical generators using hydrogen-oxygen cells were chosen to provide the main supplies on the Apollo spacecraft for landing on the surface of the moon in 1969. An added advantage of the cells was that they simultaneously provided water. NRDC was largely responsible for the forma-tion of Energy Conversion Ltd, a company that was set up to exploit Bacon's patents and to manufacture fuel cells, and which was supported by British Ropes Ltd, British Petroleum and Guest, Keen \& Nettlefold Ltd at Basingstoke. Bacon was their full-time consultant. In 1971 Energy Conversion's operation was moved to the UK Atomic Energy Research Establishment at Harwell, as Fuel Cells Ltd. Bacon remained with them until he retired in 1973.

Bigelow was born in West Boyleston, Massachusetts, where his father struggled as a farmer, wheelwright, and chairmaker. Before he was 20, Bigelow had many different jobs, among them farm labourer, clerk, violin player and cotton-mill employee. In 1830, he went to Leicester Academy, Massachusetts, but he could not afford to go on to Harvard. He sought work in Boston, New York and elsewhere, making various inventions.

The most important of his early inventions was the power loom of 1837 for making coach lace. This loom contained all the essential features of his carpet looms, which he developed and patented two years later. He formed the Clinton Company for manufacturing carpets at Leicester, Massachusetts, but the factory became so large that its name was adopted for the town. The next twenty years saw various mechanical discoveries, while his range of looms was extended to cover Brussels, Wilton, tapestry and velvet carpets. Bigelow has been justly described as the originator of every fundamental device in these machines, which were amongst the largest textile machines of their time. The automatic insertion and withdrawal of strong wires with looped ends was the means employed to raise the looped pile of the Brussels carpets, while thinner wires with a knife blade at the end raised and then severed the loops to create the rich Wilton pile. At the Great Exhibition in 1851, it was declared that his looms made better carpets than any from hand looms. He also developed other looms for special materials.

He became a noted American economist, writing two books about tariff problems, advocating that the United States should not abandon its protectionist policies. In 1860 he was narrowly defeated in a Congress election. The following year he was a member of the committee that established the Massachusetts Institute of Technology.

John George Bodmer (as he was known in England) showed signs of great inventive ability even as a child. Soon after completing his apprenticeship to a local millwright, he set up his own work-shop at Zussnacht. One of his first inventions, in 1805, was a shell which exploded on impact. Soon after this he went into partnership with Baron d'Eichthal to establish a cotton mill at St Blaise in the Black Forest. Bodmer designed the water-wheels and all the machinery. A few years later they established a factory for firearms and Bodmer designed special machine tools and developed a system of interchangeable manufacture comparable with American developments at that time. More inventions followed, including a detachable bayonet for breech-loading rifles and a rifled, breech-loading cannon for 12 lb (5.4 kg) shells.

Bodmer was appointed by the Grand Duke of Baden to the posts of Director General of the Government Iron Works and Inspector of Artillery. He left St Blaise in 1816 and entered completely into the service of the Grand Duke, but before taking up his duties he visited Britain for the first time and made an intensive five-month tour of textile mills, iron works, workshops and similar establishments.

In 1821 he returned to Switzerland and was engaged in setting up cotton mills and other engineering works. In 1824 he went back to England, where he obtained a patent for his improvements in cotton machinery and set up a mill near Bolton incorporating his ideas. His health failing, he was obliged to return to Switzerland in 1828, but he was soon busy with engineering works there and in France. In 1833 he went to England again, first to Bolton and four years later to Manchester in partnership with H.H.Birley. In the next ten years he patented many more inventions in the fields of textile machinery, steam engines and machine tools. These included a balanced steam engine, a mechanical stoker, steam engine valve gear, gear-cutting machines and a circular planer or vertical lathe, anticipating machines of this type later developed in America by E.P. Bullard. The metric system was used in his workshops and in gearing calculations he introduced the concept of diametral pitch, which then became known as "Manchester Pitch". The balanced engine was built in stationary form and in two locomotives, but although their running was remarkably smooth the additional complication prevented their wider use.

After the death of H.H.Birley in 1846, Bodmer removed to London until 1848, when he went to Austria. About 1860 he returned to his native town of Zurich. He remained actively engaged in all kinds of inventions up to the end of his life. He obtained fourteen British patents, each of which describes many inventions; two of these patents were extended beyond the normal duration of fourteen years. Two others were obtained on his behalf, one by his brother James in 1813 for his cannon and one relating to railways by Charles Fox in 1847. Many of his inventions had little direct influence but anticipated much later developments. His ideas were sound and some of his engines and machine tools were in use for over sixty years. He was elected a Member of the Institution of Civil Engineers in 1835.

Although known as Clement in his professional life, his baptism at Asby and his death were registered under the name of Joseph Clemmet. He worked as a slater until the age of 23, but his interest in mechanics led him to spend much of his spare time in the local blacksmith's shop. By studying books on mechanics borrowed from his cousin, a watchmaker, he taught himself and with the aid of the village blacksmith made his own lathe. By 1805 he was able to give up the slating trade and find employment as a mechanic in a small factory at Kirkby Stephen. From there he moved to Carlisle for two years, and then to Glasgow where, while working as a turner, he took lessons in drawing; he had a natural talent and soon became an expert draughtsman. From about 1809 he was employed by Leys, Mason \& Co. of Aberdeen designing and making power looms. For this work he built a screw-cutting lathe and continued his self-education. At the end of 1813, having saved about £100, he made his way to London, where he soon found employment as a mechanic and draughtsman. Within a few months he was engaged by Joseph Bramah, and after a trial period a formal agreement dated 1 April 1814 was made by which Clement was to be Chief Draughtsman and Superintendent of Bramah's Pimlico works for five years. However, Bramah died in December 1814 and after his sons took over the business it was agreed that Clement should leave before the expiry of the five-year period. He soon found employment as Chief Draughtsman with Henry Maudslay \& Co. By 1817 Clement had saved about £500, which enabled him to establish his own business at Prospect Place, Newington Butts, as a mechanical draughtsman and manufacturer of high-class machinery. For this purpose he built lathes for his own use and invented various improvements in their detailed design. In 1827 he designed and built a facing lathe which incorporated an ingenious system of infinitely variable belt gearing. He had also built his own planing machine by 1820 and another, much larger one in 1825. In 1828 Clement began making fluted taps and dies and standardized the screw threads, thus anticipating on a small scale the national standards later established by Sir Joseph Whitworth. Because of his reputation for first-class workmanship, Clement was in the 1820s engaged by Charles Babbage to carry out the construction of his first Difference Engine.

Anton Flettner was an engineer with a great interest in hydraulics and aerodynamics. At the beginning of the First World War Flettner was recruited by Zeppelin to investigate the possibility of radio-controlled airships as guided missiles. In 1915 he constructed a small radio-controlled tank equipped to cut barbed-wire defences; the military experts rejected it, but he was engaged to investigate radio-controlled pilotless aircraft and he invented a servo-control device to assist their control systems. These servo-controls, or trim tabs, were used on large German bombers towards the end of the war. In 1924 he invented a sailing ship powered by rotating cylinders, but although one of these crossed the Atlantic they were never a commercial success. He also invented a windmill and a marine rudder. In the late 1920s Flettner turned his attention to rotating-wing aircraft, and in 1931 he built a helicopter with small engines mounted on the rotor blades. Progress was slow and it was abandoned after being damaged during testing in 1934. An autogiro followed in 1936, but it caught fire on a test flight and was destroyed. Undeterred, Flettner continued his development work on helicopters and in 1937 produced the Fl 185, which had a single rotor to provide lift and two propellers on outriggers to combat the torque and provide forward thrust. This arrangement was not a great success, so he turned to twin contra-rotating rotors, as used by his rival Focke, but broke new ground by using intermeshing rotors to make a more compact machine. The Fl 265 with its "egg-beater" rotors was ordered by the German navy in 1938 and flew the following year. After exhaustive testing, Flettner improved his design and produced the two-seater Fl 282 Kolibri, which flew in 1940 and became the only helicopter to be used operationally during the Second World War.

After the war, Flettner moved to the United States where his intermeshing-rotor idea was developed by the Kaman Aircraft Corporation.

Alfred's father, Immanuel Nobel, builder, industrialist and inventor, encouraged his sons to follow his example of inventiveness. Alfred's education was interrupted when the family moved to St Petersburg, but was continued privately and was followed by a period of travel. He thus acquired a good knowledge of chemistry and became an excellent linguist.

During the Crimean War, Nobel worked for his father's firm in supplying war materials. The cancellation of agreements with the Russian Government at the end of the war bankrupted the firm, but Alfred and his brother Immanuel continued their interest in explosives, working on improved methods of making nitroglycerine. In 1863 Nobel patented his first major invention, a detonator that introduced the principle of detonation by shock, by using a small charge of nitroglycerine in a metal cap with detonating or fulminating mercury. Two years later Nobel set up the world's first nitroglycerine factory in an isolated area outside Stockholm. This led to several other plants and improved methods for making and handling the explosive. Yet Nobel remained aware of the dangers of liquid nitroglycerine, and after many experiments he was able in 1867 to take out a patent for dynamite, a safe, solid and pliable form of nitroglycerine, mixed with kieselguhr. At last, nitroglycerine, discovered by Sobrero in 1847, had been transformed into a useful explosive; Nobel began to promote a worldwide industry for its manufacture. Dynamite still had disadvantages, and Nobel continued his researches until, in 1875, he achieved blasting gelatin, a colloidal solution of nitrocellulose (gun cotton) in nitroglycerine. In many ways it proved to be the ideal explosive, more powerful than nitroglycerine alone, less sensitive to shock and resistant to moisture. It was variously called Nobel's Extra Dynamite, blasting gelatin and gelignite. It immediately went into production.

Next, Nobel sought a smokeless powder for military purposes, and in 1887 he obtained a nearly smokeless blasting powder using nitroglycerine and nitrocellulose with 10 per cent camphor. Finally, a progressive, smokeless blasting powder was developed in 1896 at his San Remo laboratory.

Nobel's interests went beyond explosives into other areas, such as electrochemistry, optics and biology; his patents amounted to 355 in various countries. However, it was the manufacture of explosives that made him a multimillionaire. At his death he left over £2 million, which he willed to funding awards "to those who during the preceding year, shall have conferred the greatest benefit on mankind".

Phillips was educated in Paris, at the Ecole Polytechnic and the Ecole des Mines. In 1849 he was awarded a doctorate in mathematical sciences by the University of Paris. He had a varied career in industry, academic and government institutions, rising to be Inspector- General of Mines in 1882.

It was well known that the balance of a watch or chronometer fitted with a simple spiral or helical spring was not isochronous, i.e. the period of the oscillation was not entirely independent of the amplitude. Watch-and chronometer-makers, notably Breguet and Arnold, had devised empirical solutions to the problem by altering the curvature of the end of the balance spring. In 1858 Phillips was encouraged to tackle the problem mathematically, and two years later he published a complete solution for the helical balance spring and a partial solution for the more complex spiral spring. Eleven years later he was able to achieve a complete solution for the spiral spring by altering the curvature of both ends of the spring. Phillips published a series of typical curves that the watch-or chronometer-maker could use to shape the ends of the balance spring.

As a Jewish boy in Russia, Sarnoff spent several years preparing to be a Talmudic Scholar, but in 1900 the family emigrated to the USA and settled in Albany, New York. While at public school and at the Pratt Institute in Brooklyn, New York, he helped the family finances by running errands, selling newspapers and singing the liturgy in the synagogue. After a short period as a messenger boy with the Commercial Cable Company, in 1906 he became an office boy with the Marconi Wireless Telegraph Company of America (see G. Marconi). Having bought a telegraph instrument with his first earnings, he taught himself Morse code and was made a junior telegraph operator in 1907. The following year he became a wireless operator at Nantucket Island, then in 1909 he became Manager of the Marconi station at Sea Gate, New York. After two years at sea he returned to a shore job as wireless operator at the world's most powerful station at Wanamaker's store in Manhattan. There, on 14 April 1912, he picked up the distress signals from the sinking iner Titanic, remaining at his post for three days.

Rewarded by rapid promotion (Chief Radio Inspector 1913, Contract Manager 1914, Assistant Traffic Manager 1915, Commercial Manager 1917) he proposed the introduction of commercial radio broadcasting, but this received little response. Consequently, in 1919 he took the job of Commercial Manager of the newly formed Radio Corporation of America (RCA), becoming General Manager in 1921, Vice- President in 1922, Executive Vice-President in 1929 and President in 1930. In 1921 he was responsible for the broadcasting of the Dempsey-Carpentier title-fight, as a result of which RCA sold $80 million worth of radio receivers in the following three years. In 1926 he formed the National Broadcasting Company (NBC). Rightly anticipating the development of television, in 1928 he inaugurated an experimental NBC television station and in 1939 demonstrated television at the New York World Fair. Because of his involvement with the provision of radio equipment for the armed services, he was made a lieutenant-colonel in the US Signal Corps Reserves in 1924, a full colonel in 1931 and, while serving as a communications consultant to General Eisenhower during the Second World War, Brigadier General in 1944.

With the end of the war, RCA became a major manufacturer of television receivers and then invested greatly in the ultimately successful development of shadowmask tubes and receivers for colour television. Chairman and Chief Executive from 1934, Sarnoff held the former post until his retirement in 1970.

Robert Wilson was the son of a fisherman who was drowned in a lifeboat rescue attempt in December 1810. He received only a meagre education and was apprenticed to a joiner. From a very early age he was much concerned with the idea of applying screw propellers to ships, and his invention was approved by the Highland Society and by the Scottish Society of Arts, who in 1832 awarded him a silver medal. He must have gained some experience as a mechanic and while working on his invention he made the acquaintance of James Nasmyth. In 1838 he became Works Manager at Nasmyth's Bridgewater Foundry and made an important contribution to the success of the steam-hammer by developing the self-acting control gear. From 1845 he was with the Low Moor Ironworks near Bradford, Yorkshire, but in July 1856 he returned to the Bridgewater Foundry so that he was able to take over as Managing Partner after Nasmyth's early retirement at the end of 1856. In 1867 the name of the firm was changed to Nasmyth, Wilson \& Co., and Wilson remained a partner until May 1882, when the firm became a limited company. Wilson often returned to his first invention, and two of his many patents related to improvements in screw propellers. In 1880 he received £500 from the War Department for the use of his double-action screw propeller as applied to the torpedo.
