21 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

22 Holtzapffel, Charles
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 1806 London, Englandd. 11 April 1847 London, England[br]English mechanical engineer and author of Turning and Mechanical Manipulation.[br]Charles Holtzapffel was the son of John Holtzapffel, a native of Germany who settled in London c.1787 and set up as a manufacturer of lathes and tools for amateur mechanics. Charles Holtzapffel received a good English education and training in his father's workshop, and subsequently became a partner and ultimately succeeded to the business. He was engaged in the construction of machinery for printing banknotes, of lathes for cutting rosettes and for ornamental and plain turning. Holtzapffel is chiefly remembered for his monumental work entitled Turning and Mechanical Manipulation, intended as a work of general reference and practical instruction on the lathe. Publication began in 1843 and only the first two volumes were published in his lifetime. A third volume was edited by his widow from his notes and published shortly after his death. The fourth and fifth volumes were completed by his son, John Jacob Holtzapffel, more than thirty years later. Holtzapffel was an Associate of the Institution of Civil Engineers and served on its Council: he was also a member of the Society of Arts and Chairman of its Committee on Mechanics.RTS -
23 Carnot, Nicolas Léonard Sadi
SUBJECT AREA: Steam and internal combustion engines[br]b. 1 June 1796 Paris, Franced. 24 August 1831 Paris, France[br]French laid the foundations for modern thermodynamics through his book Réflexions sur la puissance motrice du feu when he stated that the efficiency of an engine depended on the working substance and the temperature drop between the incoming and outgoing steam.[br]Sadi was the eldest son of Lazare Carnot, who was prominent as one of Napoleon's military and civil advisers. Sadi was born in the Palais du Petit Luxembourg and grew up during the Napoleonic wars. He was tutored by his father until in 1812, at the minimum age of 16, he entered the Ecole Polytechnique to study stress analysis, mechanics, descriptive geometry and chemistry. He organized the students to fight against the allies at Vincennes in 1814. He left the Polytechnique that October and went to the Ecole du Génie at Metz as a student second lieutenant. While there, he wrote several scientific papers, but on the Restoration in 1815 he was regarded with suspicion because of the support his father had given Napoleon. In 1816, on completion of his studies, Sadi became a second lieutenant in the Metz engineering regiment and spent his time in garrison duty, drawing up plans of fortifications. He seized the chance to escape from this dull routine in 1819 through an appointment to the army general staff corps in Paris, where he took leave of absence on half pay and began further courses of study at the Sorbonne, Collège de France, Ecole des Mines and the Conservatoire des Arts et Métiers. He was inter-ested in industrial development, political economy, tax reform and the fine arts.It was not until 1821 that he began to concentrate on the steam-engine, and he soon proposed his early form of the Carnot cycle. He sought to find a general solution to cover all types of steam-engine, and reduced their operation to three basic stages: an isothermal expansion as the steam entered the cylinder; an adiabatic expansion; and an isothermal compression in the condenser. In 1824 he published his Réflexions sur la puissance motrice du feu, which was well received at the time but quickly forgotten. In it he accepted the caloric theory of heat but pointed out the impossibility of perpetual motion. His main contribution to a correct understanding of a heat engine, however, lay in his suggestion that power can be produced only where there exists a temperature difference due "not to an actual consumption of caloric but to its transportation from a warm body to a cold body". He used the analogy of a water-wheel with the water falling around its circumference. He proposed the true Carnot cycle with the addition of a final adiabatic compression in which motive power was con sumed to heat the gas to its original incoming temperature and so closed the cycle. He realized the importance of beginning with the temperature of the fire and not the steam in the boiler. These ideas were not taken up in the study of thermodynartiics until after Sadi's death when B.P.E.Clapeyron discovered his book in 1834.In 1824 Sadi was recalled to military service as a staff captain, but he resigned in 1828 to devote his time to physics and economics. He continued his work on steam-engines and began to develop a kinetic theory of heat. In 1831 he was investigating the physical properties of gases and vapours, especially the relationship between temperature and pressure. In June 1832 he contracted scarlet fever, which was followed by "brain fever". He made a partial recovery, but that August he fell victim to a cholera epidemic to which he quickly succumbed.[br]Bibliography1824, Réflexions sur la puissance motrice du feu; pub. 1960, trans.
