15 Bell, Alexander Graham
SUBJECT AREA: Telecommunications[br]b. 3 March 1847 Edinburgh, Scotlandd. 3 August 1922 Beinn Bhreagh, Baddeck, Cape Breton Island, Nova Scotia, Canada[br]Scottish/American inventor of the telephone.[br]Bell's grandfather was a professor of elocution in London and his father an authority on the physiology of the voice and on elocution; Bell was to follow in their footsteps. He was educated in Edinburgh, leaving school at 13. In 1863 he went to Elgin, Morayshire, as a pupil teacher in elocution, with a year's break to study at Edinburgh University; it was in 1865, while still in Elgin, that he first conceived the idea of the electrical transmission of speech. He went as a master to Somersetshire College, Bath (now in Avon), and in 1867 he moved to London to assist his father, who had taken up the grandfather's work in elocution. In the same year, he matriculated at London University, studying anatomy and physiology, and also began teaching the deaf. He continued to pursue the studies that were to lead to the invention of the telephone. At this time he read Helmholtz's The Sensations of Tone, an important work on the theory of sound that was to exert a considerable influence on him.In 1870 he accompanied his parents when they emigrated to Canada. His work for the deaf gained fame in both Canada and the USA, and in 1873 he was apponted professor of vocal physiology and the mechanics of speech at Boston University, Massachusetts. There, he continued to work on his theory that sound wave vibrations could be converted into a fluctuating electric current, be sent along a wire and then be converted back into sound waves by means of a receiver. He approached the problem from the background of the theory of sound and voice production rather than from that of electrical science, and by 1875 he had succeeded in constructing a rough model. On 7 March 1876 Bell spoke the famous command to his assistant, "Mr Watson, come here, I want you": this was the first time a human voice had been transmitted along a wire. Only three days earlier, Bell's first patent for the telephone had been granted. Almost simultaneously, but quite independently, Elisha Gray had achieved a similar result. After a period of litigation, the US Supreme Court awarded Bell priority, although Gray's device was technically superior.In 1877, three years after becoming a naturalized US citizen, Bell married the deaf daughter of his first backer. In August of that year, they travelled to Europe to combine a honeymoon with promotion of the telephone. Bell's patent was possibly the most valuable ever issued, for it gave birth to what later became the world's largest private service organization, the Bell Telephone Company.Bell had other scientific and technological interests: he made improvements in telegraphy and in Edison's gramophone, and he also developed a keen interest in aeronautics, working on Curtiss's flying machine. Bell founded the celebrated periodical Science.[br]Principal Honours and DistinctionsLegion of Honour; Hughes Medal, Royal Society, 1913.Further ReadingObituary, 7 August 1922, The Times.

16 Caetano, Marcello José das Neves Alves
(19061980)Marcello Caetano, as the last prime minister of the Estado Novo, was both the heir and successor of Antônio de Oliveira Salazar. In a sense, Caetano was one of the founders and sustainers of this unusual regime and, at various crucial stages of its long life, Caetano's contribution was as important as Salazar's.Born in Lisbon in 1906 to a middle-class family, Caetano was a member of the student generation that rebelled against the unstable parliamentary First Republic and sought answers to Portugal's legion of troubles in conservative ideologies such as integralism, Catholic reformism, and the Italian Fascist model. One of the most brilliant students at the University of Lisbon's Law School, Caetano soon became directly involved in government service in various ministries, including Salazar's Ministry of Finance. When Caetano was not teaching full-time at the law school in Lisbon and influencing new generations of students who became critical of the regime he helped construct, Caetano was in important government posts and working on challenging assignments. In the 1930s, he participated in reforms in the Ministry of Finance, in the writing of the 1933 Constitution, in the formation of the new civil code, of which he was in part the author, and in the construction of corporativism, which sought to control labor-management relations and other aspects of social engineering. In a regime largely directed by academics from the law faculties of Coimbra University and the University of Lisbon, Caetano was the leading expert on constitutional law, administrative law, political science, and colonial law. A prolific writer as both a political scientist and historian, Caetano was the author of the standard political science, administrative law, and history of law textbooks, works that remained in print and in use among students long after his exile and death.After his apprenticeship service in a number of ministries, Caetano rose steadily in the system. At age 38, he was named minister for the colonies (1944 47), and unlike many predecessors, he "went to see for himself" and made important research visits to Portugal's African territories. In 1955-58, Caetano served in the number-three position in the regime in the Ministry of the Presidency of the Council (premier's office); he left office for full-time academic work in part because of his disagreements with Salazar and others on regime policy and failures to reform at the desired pace. In 1956 and 1957, Caetano briefly served as interim minister of communications and of foreign affairs.Caetano's opportunity to take Salazar's place and to challenge even more conservative forces in the system came in the 1960s. Portugal's most prominent law professor had a public falling out with the regime in March 1962, when he resigned as rector of Lisbon University following a clash between rebellious students and the PIDE, the political police. When students opposing the regime organized strikes on the University of Lisbon campus, Caetano resigned his rectorship after the police invaded the campus and beat and arrested some students, without asking permission to enter university premises from university authorities.When Salazar became incapacitated in September 1968, President Américo Tomás named Caetano prime minister. His tasks were formidable: in the midst of remarkable economic growth in Portugal, continued heavy immigration of Portuguese to France and other countries, and the costly colonial wars in three African colonies, namely Angola, Guinea- Bissau, and Mozambique, the regime struggled to engineer essential social and political reforms, win the wars in Africa, and move toward meaningful political reforms. Caetano supported moderately important reforms in his first two years in office (1968-70), as well as the drafting of constitutional revisions in 1971 that allowed a slight liberalization of the Dictatorship, gave the opposition more room for activity, and decentrali zed authority in the overseas provinces (colonies). Always aware of the complexity of Portugal's colonial problems and of the ongoing wars, Caetano made several visits to Africa as premier, and he sought to implement reforms in social and economic affairs while maintaining the expensive, divisive military effort, Portugal's largest armed forces mobilization in her history.Opposed by intransigent right-wing forces in various sectors in both Portugal and Africa, Caetano's modest "opening" of 1968-70 soon narrowed. Conservative forces in the military, police, civil service, and private sectors opposed key political reforms, including greater democratization, while pursuing the military solution to the African crisis and personal wealth. A significant perspective on Caetano's failed program of reforms, which could not prevent the advent of a creeping revolution in society, is a key development in the 1961-74 era of colonial wars: despite Lisbon's efforts, the greater part of Portuguese emigration and capital investment during this period were directed not to the African colonies but to Europe, North America, and Brazil.Prime Minister Caetano, discouraged by events and by opposition to his reforms from the so-called "Rheumatic Brigade" of superannuated regime loyalists, attempted to resign his office, but President Américo Tomás convinced him to remain. The publication and public reception of African hero General Antônio Spinola's best-selling book Portugal e Futuro (Portugal and the Future) in February 1974 convinced the surprised Caetano that a coup and revolution were imminent. When the virtually bloodless, smoothly operating military coup was successful in what became known as the Revolution of 25 April 1974, Caetano surrendered to the Armed Forces Movement in Lisbon and was flown to Madeira Island and later to exile in Brazil, where he remained for the rest of his life. In his Brazilian exile, Caetano was active writing important memoirs and histories of the Estado Novo from his vantage point, teaching law at a private university in Rio de Janeiro, and carrying on a lively correspondence with persons in Portugal. He died at age 74, in 1980, in Brazil.Historical dictionary of Portugal > Caetano, Marcello José das Neves Alves

17 Cayley, Sir George
SUBJECT AREA: Aerospace[br]b. 27 December 1773 Scarborough, Englandd. 15 December 1857 Brompton Hall, Yorkshire, England[br]English pioneer who laid down the basic principles of the aeroplane in 1799 and built a manned glider in 1853.[br]Cayley was born into a well-to-do Yorkshire family living at Brompton Hall. He was encouraged to study mathematics, navigation and mechanics, particularly by his mother. In 1792 he succeeded to the baronetcy and took over the daunting task of revitalizing the run-down family estate.The first aeronautical device made by Cayley was a copy of the toy helicopter invented by the Frenchmen Launoy and Bienvenu in 1784. Cayley's version, made in 1796, convinced him that a machine could "rise in the air by mechanical means", as he later wrote. He studied the aerodynamics of flight and broke away from the unsuccessful ornithopters of his predecessors. In 1799 he scratched two sketches on a silver disc: one side of the disc showed the aerodynamic force on a wing resolved into lift and drag, and on the other side he illustrated his idea for a fixed-wing aeroplane; this disc is preserved in the Science Museum in London. In 1804 he tested a small wing on the end of a whirling arm to measure its lifting power. This led to the world's first model glider, which consisted of a simple kite (the wing) mounted on a pole with an adjustable cruciform tail. A full-size glider followed in 1809 and this flew successfully unmanned. By 1809 Cayley had also investigated the lifting properties of cambered wings and produced a low-drag aerofoil section. His aim was to produce a powered aeroplane, but no suitable engines were available. Steam-engines were too heavy, but he experimented with a gunpowder motor and invented the hot-air engine in 1807. He published details of some of his aeronautical researches in 1809–10 and in 1816 he wrote a paper on airships. Then for a period of some twenty-five years he was so busy with other activities that he largely neglected his aeronautical researches. It was not until 1843, at the age of 70, that he really had time to pursue his quest for flight. The Mechanics' Magazine of 8 April 1843 published drawings of "Sir George Cayley's Aerial Carriage", which consisted of a helicopter design with four circular lifting rotors—which could be adjusted to become wings—and two pusher propellers. In 1849 he built a full-size triplane glider which lifted a boy off the ground for a brief hop. Then in 1852 he proposed a monoplane glider which could be launched from a balloon. Late in 1853 Cayley built his "new flyer", another monoplane glider, which carried his coachman as a reluctant passenger across a dale at Brompton, Cayley became involved in public affairs and was MP for Scarborough in 1832.

[br]b. 31 March 1854 Glasgow, Scotlandd. 12 November 1932 Ewhurst, Surrey, England[br]Scottish mechanical engineer, inventor of the two-stroke internal combustion engine.[br]Clerk began his engineering training at about the age of 15 in the drawing office of H.O.Robinson \& Company, Glasgow, and in his father's works. Meanwhile, he studied at the West of Scotland Technical College and then, from 1871 to 1876, at Anderson's College, Glasgow, and at the Yorkshire College of Science, Leeds. Here he worked under and then became assistant to the distinguished chemist T.E.Thorpe, who set him to work on the fractional distillation of petroleum, which was to be useful to him in his later work. At that time he had intended to become a chemical engineer, but seeing a Lenoir gas engine at work, after his return to Glasgow, turned his main interest to gas and other internal combustion engines. He pursued his investigations first at Thomson, Sterne \& Company (1877–85) and then at Tangyes of Birmingham (1886–88. In 1888 he began a lifelong partnership in Marks and Clerk, consulting engineers and patent agents, in London.Beginning his work on gas engines in 1876, he achieved two patents in the two following years. In 1878 he made his principal invention, patented in 1881, of an engine working on the two-stroke cycle, in which the piston is powered during each revolution of the crankshaft, instead of alternate revolutions as in the Otto four-stroke cycle. In this engine, Clerk introduced supercharging, or increasing the pressure of the air intake. Many engines of the Clerk type were made but their popularity waned after the patent for the Otto engine expired in 1890. Interest was later revived, particularly for application to large gas engines, but Clerk's engine eventually came into its own where simple, low-power motors are needed, such as in motor cycles or motor mowers.Clerk's work on the theory and design of gas engines bore fruit in the book The Gas Engine (1886), republished with an extended text in 1909 as The Gas, Petrol and Oil Engine; these and a number of papers in scientific journals won him international renown. During and after the First World War, Clerk widened the scope of his interests and served, often as chairman, on many bodies in the field of science and industry.[br]Principal Honours and DistinctionsKnighted 1917; FRS 1908; Royal Society Royal Medal 1924; Royal Society of Arts Alber Medal 1922.Further ReadingObituary Notices of Fellows of the Royal Society, no. 2, 1933.LRD -
19 Denny, William
SUBJECT AREA: Ports and shipping[br]b. 25 May 1847 Dumbarton, Scotlandd. 17 March 1887 Buenos Aires, Argentina[br]Scottish naval architect and partner in the leading British scientific shipbuilding company.[br]From 1844 until 1962, the Clyde shipyard of William Denny and Brothers, Dumbarton, produced over 1,500 ships, trained innumerable students of all nationalities in shipbuilding and marine engineering, and for the seventy-plus years of their existence were accepted worldwide as the leaders in the application of science to ship design and construction. Until the closure of the yard members of the Denny family were among the partners and later directors of the firm: they included men as distinguished as Dr Peter Denny (1821(?)–95), Sir Archibald Denny (1860–1936) and Sir Maurice Denny (1886– 1955), the main collaborator in the design of the Denny-Brown ship stabilizer.One of the most influential of this shipbuilding family was William Denny, now referred to as William 3! His early education was at Dumbarton, then on Jersey and finally at the Royal High School, Edinburgh, before he commenced an apprenticeship at his father's shipyard. From the outset he not only showed great aptitude for learning and hard work but also displayed an ability to create good relationships with all he came into contact with. At the early age of 21 he was admitted a partner of the shipbuilding business of William Denny and Brothers, and some years later also of the associated engineering firm of Denny \& Co. His deep-felt interest in what is now known as industrial relations led him in 1871 to set up a piecework system of payment in the shipyard. In this he was helped by the Yard Manager, Richard Ramage, who later was to found the Leith shipyard, which produced the world's most elegant steam yachts. This research was published later as a pamphlet called The Worth of Wages, an unusual and forward-looking action for the 1860s, when Denny maintained that an absentee employer should earn as much contempt and disapproval as an absentee landlord! In 1880 he initiated an awards scheme for all company employees, with grants and awards for inventions and production improvements. William Denny was not slow to impose new methods and to research naval architecture, a special interest being progressive ship trials with a view to predicting effective horsepower. In time this led to his proposal to the partners to build a ship model testing tank beside the Dumbarton shipyard; this scheme was completed in 1883 and was to the third in the world (after the Admiralty tank at Torquay, managed by William Froude and the Royal Netherlands Navy facility at Amsterdam, under B.J. Tideman. In 1876 the Denny Shipyard started work with mild-quality shipbuilding steel on hulls for the Irrawaddy Flotilla Company, and in 1879 the world's first two ships of any size using this weight-saving material were produced: they were the Rotomahana for the Union Steamship Company of New Zealand and the Buenos Ayrean for the Allan Line of Glasgow. On the naval-architecture side he was involved in Denny's proposals for standard cross curves of stability for all ships, which had far-reaching effects and are now accepted worldwide. He served on the committee working on improvements to the Load Line regulations and many other similar public bodies. After a severe bout of typhoid and an almost unacceptable burden of work, he left the United Kingdom for South America in June 1886 to attend to business with La Platense Flotilla Company, an associate company of William Denny and Brothers. In March the following year, while in Buenos Aires, he died by his own hand, a death that caused great and genuine sadness in the West of Scotland and elsewhere.[br]Principal Honours and DistinctionsPresident, Institution of Engineers and Shipbuilders in Scotland 1886. FRS Edinburgh 1879.BibliographyWilliam Denny presented many papers to various bodies, the most important being to the Institution of Naval Architects and to the Institution of Engineers and Shipbuilders in Scotland. The subjects include: trials results, the relation of ship speed to power, Lloyd's Numerals, tonnage measurement, layout of shipyards, steel in shipbuilding, cross curves of stability, etc.Further ReadingA.B.Bruce, 1889, The Life of William Denny, Shipbuilder, London: Hodder \& Stoughton.Denny Dumbarton 1844–1932 (a souvenir hard-back produced for private circulation by the shipyard).Fred M.Walker, 1984, Song of the Clyde.

20 Hunter, Matthew Albert
SUBJECT AREA: Metallurgy[br]b. 9 November 1878 Auckland Province, New Zealandd. 24 March 1961 Troy, New York, USA[br]New Zealand/American technologist and academic who was a pioneer in the production of metallic titanium.[br]Hunter arrived in England in 1902, the seventh in the succession of New Zealand students nominated for the 1851 Exhibition science research scholarships (the third, in 1894, having been Ernest Rutherford). He intended to study the metallurgy of tellurides at the Royal School of Mines, but owing to the death of the professor concerned, he went instead to University College London, where his research over two years involved the molecular aggregation of liquified gases. In 1904–5 he spent a third year in Göttingen, Paris and Karlsruhe. Hunter then moved to the USA, beginning work in 1906 with the General Electric Company in Schenectady. His experience with titanium came as part of a programme to try to discover satisfactory lamp-filament materials. He and his colleagues achieved more success in producing moderately pure titanium than previous workers had done, but found the metal's melting temperature inadequate. However, his research formed the basis for the "Hunter sodium process", a modern method for producing commercial quantities of titanium. In 1908 he was appointed Assistant Professor of Electrochemistry and Physics at Rensselaer Polytechnic Institute in Troy, New York, where he was to remain until his retirement in 1949 as Dean Emeritus. In the 1930s he founded and headed the Institute's Department of Metallurgical Engineering. As a consultant, he was associated with the development of Invar, Managanin and Constantan alloys.[br]Principal Honours and Distinctions1851 Great Exhibition science research scholar 1902–5.
