2 Pretsch, Paul
[br]b. 1808 Vienna, Austriad. 1873 Vienna, Austria[br]Austrian printer and inventor of photogalvanography, one of the earliest commercial photomechanical printing processes.[br]The son of a goldsmith, Pretsch learned the printing trade in Vienna, where he worked until 1831. He then took up a series of posts in Germany, Belgium and Holland before returning to Vienna, where in 1842 he joined the Imperial State Printing Office. The office was equipped with a photographic studio, and Pretsch was encouraged to explore applications of photography to printing and the graphic arts. In 1851 he was sent to London to take responsibility for the Austrian printing exhibits of the Great Exhibition. This event proved to be a significant international show case for photography and Pretsch saw a great number of recent innovations and made many useful contacts. On returning to Vienna, he began to develop a process for producing printing plates from photographs. Using Talbot's discovery that bichromated gelatine swells in water after exposure to light, he electrotyped the relief image obtained. In 1854 Pretsch resigned from his post in Vienna and travelled back to London, where he patented his process, calling it photogalvanography. He went on to form a business, the Photo-Galvano-Graphic Company, to print and market his pictures.The Photographic Manager of the company was the celebrated photographer Roger Fenton, recently returned from his exploits on the battlefields of the Crimea. In 1856 the company issued a large serial work, Photographic Art Treasures, illustrated with Pretsch's pictures, which created considerable interest. The venture did not prove a commercial success, however, and although further plates were made and issued, Fenton found other interests to pursue and Pretsch was left to try to apply some of his ideas to lithography. This too had no successful outcome, and in 1863 Pretsch returned to Vienna. He was reappointed to a post at the Imperial State Printing Office, but his health failed and he made no further progress with his processes.[br]Bibliography9 November 1854, British patent no. 2,373. 11 August 1855, British patent no. 1,824.Further ReadingJ.M.Eder, 1945, History of Photography, trans.

8 Introduction
Portugal is a small Western European nation with a large, distinctive past replete with both triumph and tragedy. One of the continent's oldest nation-states, Portugal has frontiers that are essentially unchanged since the late 14th century. The country's unique character and 850-year history as an independent state present several curious paradoxes. As of 1974, when much of the remainder of the Portuguese overseas empire was decolonized, Portuguese society appeared to be the most ethnically homogeneous of the two Iberian states and of much of Europe. Yet, Portuguese society had received, over the course of 2,000 years, infusions of other ethnic groups in invasions and immigration: Phoenicians, Greeks, Celts, Romans, Suevi, Visigoths, Muslims (Arab and Berber), Jews, Italians, Flemings, Burgundian French, black Africans, and Asians. Indeed, Portugal has been a crossroads, despite its relative isolation in the western corner of the Iberian Peninsula, between the West and North Africa, Tropical Africa, and Asia and America. Since 1974, Portugal's society has become less homogeneous, as there has been significant immigration of former subjects from its erstwhile overseas empire.Other paradoxes should be noted as well. Although Portugal is sometimes confused with Spain or things Spanish, its very national independence and national culture depend on being different from Spain and Spaniards. Today, Portugal's independence may be taken for granted. Since 1140, except for 1580-1640 when it was ruled by Philippine Spain, Portugal has been a sovereign state. Nevertheless, a recurring theme of the nation's history is cycles of anxiety and despair that its freedom as a nation is at risk. There is a paradox, too, about Portugal's overseas empire(s), which lasted half a millennium (1415-1975): after 1822, when Brazil achieved independence from Portugal, most of the Portuguese who emigrated overseas never set foot in their overseas empire, but preferred to immigrate to Brazil or to other countries in North or South America or Europe, where established Portuguese overseas communities existed.Portugal was a world power during the period 1415-1550, the era of the Discoveries, expansion, and early empire, and since then the Portuguese have experienced periods of decline, decadence, and rejuvenation. Despite the fact that Portugal slipped to the rank of a third- or fourth-rate power after 1580, it and its people can claim rightfully an unusual number of "firsts" or distinctions that assure their place both in world and Western history. These distinctions should be kept in mind while acknowledging that, for more than 400 years, Portugal has generally lagged behind the rest of Western Europe, although not Southern Europe, in social and economic developments and has remained behind even its only neighbor and sometime nemesis, Spain.Portugal's pioneering role in the Discoveries and exploration era of the 15th and 16th centuries is well known. Often noted, too, is the Portuguese role in the art and science of maritime navigation through the efforts of early navigators, mapmakers, seamen, and fishermen. What are often forgotten are the country's slender base of resources, its small population largely of rural peasants, and, until recently, its occupation of only 16 percent of the Iberian Peninsula. As of 1139—10, when Portugal emerged first as an independent monarchy, and eventually a sovereign nation-state, England and France had not achieved this status. The Portuguese were the first in the Iberian Peninsula to expel the Muslim invaders from their portion of the peninsula, achieving this by 1250, more than 200 years before Castile managed to do the same (1492).Other distinctions may be noted. Portugal conquered the first overseas empire beyond the Mediterranean in the early modern era and established the first plantation system based on slave labor. Portugal's empire was the first to be colonized and the last to be decolonized in the 20th century. With so much of its scattered, seaborne empire dependent upon the safety and seaworthiness of shipping, Portugal was a pioneer in initiating marine insurance, a practice that is taken for granted today. During the time of Pombaline Portugal (1750-77), Portugal was the first state to organize and hold an industrial trade fair. In distinctive political and governmental developments, Portugal's record is more mixed, and this fact suggests that maintaining a government with a functioning rule of law and a pluralist, representative democracy has not been an easy matter in a country that for so long has been one of the poorest and least educated in the West. Portugal's First Republic (1910-26), only the third republic in a largely monarchist Europe (after France and Switzerland), was Western Europe's most unstable parliamentary system in the 20th century. Finally, the authoritarian Estado Novo or "New State" (1926-74) was the longest surviving authoritarian system in modern Western Europe. When Portugal departed from its overseas empire in 1974-75, the descendants, in effect, of Prince Henry the Navigator were leaving the West's oldest empire.Portugal's individuality is based mainly on its long history of distinc-tiveness, its intense determination to use any means — alliance, diplomacy, defense, trade, or empire—to be a sovereign state, independent of Spain, and on its national pride in the Portuguese language. Another master factor in Portuguese affairs deserves mention. The country's politics and government have been influenced not only by intellectual currents from the Atlantic but also through Spain from Europe, which brought new political ideas and institutions and novel technologies. Given the weight of empire in Portugal's past, it is not surprising that public affairs have been hostage to a degree to what happened in her overseas empire. Most important have been domestic responses to imperial affairs during both imperial and internal crises since 1415, which have continued to the mid-1970s and beyond. One of the most important themes of Portuguese history, and one oddly neglected by not a few histories, is that every major political crisis and fundamental change in the system—in other words, revolution—since 1415 has been intimately connected with a related imperial crisis. The respective dates of these historical crises are: 1437, 1495, 1578-80, 1640, 1820-22, 1890, 1910, 1926-30, 1961, and 1974. The reader will find greater detail on each crisis in historical context in the history section of this introduction and in relevant entries.LAND AND PEOPLEThe Republic of Portugal is located on the western edge of the Iberian Peninsula. A major geographical dividing line is the Tagus River: Portugal north of it has an Atlantic orientation; the country to the south of it has a Mediterranean orientation. There is little physical evidence that Portugal is clearly geographically distinct from Spain, and there is no major natural barrier between the two countries along more than 1,214 kilometers (755 miles) of the Luso-Spanish frontier. In climate, Portugal has a number of microclimates similar to the microclimates of Galicia, Estremadura, and Andalusia in neighboring Spain. North of the Tagus, in general, there is an Atlantic-type climate with higher rainfall, cold winters, and some snow in the mountainous areas. South of the Tagus is a more Mediterranean climate, with hot, dry, often rainless summers and cool, wet winters. Lisbon, the capital, which has a fifth of the country's population living in its region, has an average annual mean temperature about 16° C (60° F).For a small country with an area of 92,345 square kilometers (35,580 square miles, including the Atlantic archipelagos of the Azores and the Madeiras), which is about the size of the state of Indiana in the United States, Portugal has a remarkable diversity of regional topography and scenery. In some respects, Portugal resembles an island within the peninsula, embodying a unique fusion of European and non-European cultures, akin to Spain yet apart. Its geography is a study in contrasts, from the flat, sandy coastal plain, in some places unusually wide for Europe, to the mountainous Beira districts or provinces north of the Tagus, to the snow-capped mountain range of the Estrela, with its unique ski area, to the rocky, barren, remote Trás-os-Montes district bordering Spain. There are extensive forests in central and northern Portugal that contrast with the flat, almost Kansas-like plains of the wheat belt in the Alentejo district. There is also the unique Algarve district, isolated somewhat from the Alentejo district by a mountain range, with a microclimate, topography, and vegetation that resemble closely those of North Africa.Although Portugal is small, just 563 kilometers (337 miles) long and from 129 to 209 kilometers (80 to 125 miles) wide, it is strategically located on transportation and communication routes between Europe and North Africa, and the Americas and Europe. Geographical location is one key to the long history of Portugal's three overseas empires, which stretched once from Morocco to the Moluccas and from lonely Sagres at Cape St. Vincent to Rio de Janeiro, Brazil. It is essential to emphasize the identity of its neighbors: on the north and east Portugal is bounded by Spain, its only neighbor, and by the Atlantic Ocean on the south and west. Portugal is the westernmost country of Western Europe, and its shape resembles a face, with Lisbon below the nose, staring into theAtlantic. No part of Portugal touches the Mediterranean, and its Atlantic orientation has been a response in part to turning its back on Castile and Léon (later Spain) and exploring, traveling, and trading or working in lands beyond the peninsula. Portugal was the pioneering nation in the Atlantic-born European discoveries during the Renaissance, and its diplomatic and trade relations have been dominated by countries that have been Atlantic powers as well: Spain; England (Britain since 1707); France; Brazil, once its greatest colony; and the United States.Today Portugal and its Atlantic islands have a population of roughly 10 million people. While ethnic homogeneity has been characteristic of it in recent history, Portugal's population over the centuries has seen an infusion of non-Portuguese ethnic groups from various parts of Europe, the Middle East, and Africa. Between 1500 and 1800, a significant population of black Africans, brought in as slaves, was absorbed in the population. And since 1950, a population of Cape Verdeans, who worked in menial labor, has resided in Portugal. With the influx of African, Goan, and Timorese refugees and exiles from the empire—as many as three quarters of a million retornados ("returned ones" or immigrants from the former empire) entered Portugal in 1974 and 1975—there has been greater ethnic diversity in the Portuguese population. In 2002, there were 239,113 immigrants legally residing in Portugal: 108,132 from Africa; 24,806 from Brazil; 15,906 from Britain; 14,617 from Spain; and 11,877 from Germany. In addition, about 200,000 immigrants are living in Portugal from eastern Europe, mainly from Ukraine. The growth of Portugal's population is reflected in the following statistics:1527 1,200,000 (estimate only)1768 2,400,000 (estimate only)1864 4,287,000 first census1890 5,049,7001900 5,423,0001911 5,960,0001930 6,826,0001940 7,185,1431950 8,510,0001960 8,889,0001970 8,668,000* note decrease1980 9,833,0001991 9,862,5401996 9,934,1002006 10,642,8362010 10,710,000 (estimated) -
9 Cunhal, Álvaro
(Barreirinhas)(1913-2005)Leader of the Portuguese Communist Party (PCP), author, and ideologue. Álvaro Cunhai was a militant of the PCP since the 1930s and was secretary-general from 1961 to 1992. In the midst of Mikail Gorbachev's reforms and perestroika, Cunha refused to alter the PCP's orthodox commitment to the proletariat and Marxism-Leninism. Throughout a long career of participation in the PCP, Cunhal regularly held influential positions in the organization. In 1931, he joined the PCP while a law student in Lisbon and became secretary-general of the Portuguese Communist Youth/Juventude Comunista (JC) in 1935, which included membership in the PCP's central committee. He advanced to the PCP's secretariat in 1942, after playing a leading role in the reorganization of 1940-H that gave the party its present orthodox character. Cunhai dubbed himself "the adopted son of the proletariat" at the 1950 trial that sentenced him to 11 years in prison for communist activity. Because his father was a lawyer-painter-writer and Cunhai received a master's degree in law, his origins were neither peasant nor worker but petit-bourgeois. During his lifetime, he spent 13 years in prison, eight of which were in solitary confinement. On 3 January 1960, he and nine other mostly communist prisoners escaped from Peniche prison and fled the country. The party's main theoretician, Cunhal was elected secretary-general in 1961 and, along with other top leaders, directed the party from abroad while in exile.In the aftermath of the Revolution of 25 April 1974 that terminated the Estado Novo and ushered in democracy, Cunhal ended his exile and returned to Portugal. He played important roles in post-1974 political events ranging from leader of the communist offensive during the "hot summer" of 1975, positions of minister-without-portfolio in the first through fifth provisional governments, to his membership in parliament beginning in 1976.At the PCP's 14th Congress (1992), Carlos Carvalhas was elected secretary-general to replace Cunhal. Whatever official or unofficial position Cunhal held, however, automatically became an important position within the party. After stepping down as secretary-general, he was elected to head the party's National Council (eliminated in 1996). Many political observers have argued that Cunhal purposely picked a successor who could not outshine him, and it is true that Carvalhas does not have Cunhal's humanistic knowledge, lacks emotion, and is not as eloquent. Cunhai was known not only as a dynamic orator but also as an artist, novelist, and brilliant political tactician. He wrote under several pseudonyms, including Manuel Tiago, who published the well-known Até Amanhã, Camaradas, as well as the novel recently adapted for the film, Cinco Dias, Cinco Noites. Under his own name, he published as well a book on art theory entitled A Arte, O Artista E A Sociedade. He also published volumes of speeches and essays.Although he was among the most orthodox leaders of the major Western European Communist parties, Cunhal was not a puppet of the Soviet Union, as many claimed. He was not only a major leader at home, but also in the international communist movement. His orthodoxy was especially useful to the Soviets in their struggle to maintain cohesion in a movement threatened by division from the Eurocommunists in the 1970s. To conclude that Cunhal was a Soviet puppet is to ignore his independent decisions during the Revolution of 25 April 1974. At that time, the Soviets reportedly tried to slowCunhal's revolutionary drive because it ran counter to detente and other Soviet strategies.In many ways Cunhal's views were locked in the past. His perception and analyses of modern Portuguese revolutionary conditions did not alter radically from his experiences and analyses of revolutionary conditions in the 1940s. To Cunhal, although some conditions had changed, requiring tactical shifts, the major conflict was the same one that led to the creation of the Communist Information Bureau (Cominform) in 1947. The world was still divided into two camps: American and Western imperialism on one side, and socialism, with its goal to achieve the fullest of democracies, on the other. Cunhal continued to believe that Marxism-Leninism and scientific socialism provide the solutions to resolving the problems of the world until his death in 2005. -
10 Baudot, Jean-Maurice-Emile
[br]b. 11 September 1845 Magneux, Franced. 28 March 1903 Sceaux, France[br]French engineer who developed the multiplexed telegraph and devised a 5-bit code for data communication and control.[br]Baudot had no formal education beyond his local primary school and began his working life as a farmer, as was his father. However, in September 1869 he joined the French telegraph service and was soon sent on a course on the recently developed Hughes printing telegraph. After service in the Franco-Prussian war as a lieutenant with the military telegraph, he returned to his civilian duties in Paris in 1872. He was there encouraged to develop (in his own time!) a multiple Hughes system for time-multiplexing of several telegraph messages. By using synchronized clockwork-driven rotating switches at the transmitter and receiver he was able to transmit five messages simultaneously; the system was officially adopted by the French Post \& Telegraph Administration five years later. In 1874 he patented the idea of a 5-bit (i.e. 32-permutation) code, with equal on and off intervals, for telegraph transmission of the Roman alphabet and punctuation signs and for control of the typewriter-like teleprinter used to display the message. This code, known as the Baudot code, was found to be more economical than the existing Morse code and was widely adopted for national and international telegraphy in the twentieth century. In the 1970s it was superseded by 7—and 8-bit codes.Further development of his ideas on multiplexing led in 1894 to methods suitable for high-speed telegraphy. To commemorate his contribution to efficient telegraphy, the unit of signalling speed (i.e. the number of elements transmitted per second) is known as the baud.[br]Bibliography17 June 1874, "Système de télégraphie rapide" (Baudot's first patent).Further Reading1965, From Semaphore to Satellite, Geneva: International Telecommunications Union.P.Lajarrige, 1982, "Chroniques téléphoniques et télégraphiques", Collection historique des télécommunications.KFBiographical history of technology > Baudot, Jean-Maurice-Emile

11 Faraday, Michael
SUBJECT AREA: Electricity[br]b. 22 September 1791 Newington, Surrey, Englandd. 25 August 1867 London, England[br]English physicist, discoverer of the principles of the electric motor and dynamo.[br]Faraday's father was a blacksmith recently moved south from Westmorland. The young Faraday's formal education was limited to attendance at "a Common Day School", and then he worked as an errand boy for George Riebau, a bookseller and bookbinder in London's West End. Riebau subsequently took him as an apprentice bookbinder, and Faraday seized every opportunity to read the books that came his way, especially scientific works.A customer in the shop gave Faraday tickets to hear Sir Humphry Davy lecturing at the Royal Institution. He made notes of the lectures, bound them and sent them to Davy, asking for scientific employment. When a vacancy arose for a laboratory assistant at the Royal Institution, Davy remembered Faraday, who he took as his assistant on an 18- month tour of France, Italy and Switzerland (despite the fact that Britain and France were at war!). The tour, and especially Davy's constant company and readiness to explain matters, was a scientific education for Faraday, who returned to the Royal Institution as a competent chemist in his own right. Faraday was interested in electricity, which was then viewed as a branch of chemistry. After Oersted's announcement in 1820 that an electric current could affect a magnet, Faraday devised an arrangement in 1821 for producing continuous motion from an electric current and a magnet. This was the basis of the electric motor. Ten years later, after much thought and experiment, he achieved the converse of Oersted's effect, the production of an electric current from a magnet. This was magneto-electric induction, the basis of the electric generator.Electrical engineers usually regard Faraday as the "father" of their profession, but Faraday himself was not primarily interested in the practical applications of his discoveries. His driving motivation was to understand the forces of nature, such as electricity and magnetism, and the relationship between them. Faraday delighted in telling others about science, and studied what made a good scientific lecturer. At the Royal Institution he introduced the Friday Evening Discourses and also the Christmas Lectures for Young People, now televised in the UK every Christmas.[br]Bibliography1991, Curiosity Perfectly Satisfyed.

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

13 Kurtz, Thomas E.
SUBJECT AREA: Electronics and information technology[br]b. USA[br]American mathematician who, with Kemeny developed BASIC, a high-level computer language.[br]Kurtz took his first degree in mathematics at the University of California in Los Angeles (UCLA), where he also gained experience in numerical methods as a result of working in the National Bureau of Standards Institute for Numerical Analysis located on the campus. In 1956 he obtained a PhD in statistics at Princeton, after which he took up a post as an instructor at Dartmouth College in Hanover, New Hampshire. There he found a considerable interest in computing was already in existence, and he was soon acting as the Dartmouth contact with the New England Regional Computer Center at Massachusetts Institute of Technology, an initiative partly supported by IBM. With Kemeny, he learned the Share Assembly Language then in use, but they were concerned about the difficulty of programming computers in assembly language and of teaching it to students and colleagues at Dartmouth. In 1959 the college obtained an LGP-30 computer and Kurtz became the first Director of the Dartmouth Computer Center. However, the small memory (4 k) of this 30-bit machine precluded its use with the recently available high-level language Algol 58. Therefore, with Kemeny, he set about developing a simple language and operating system that would use simple English commands and be easy to learn and use. This they called the Beginners All-purpose Symbolic Instruction Code (BASIC). At the same time they jointly supervised the design and development of a time-sharing system suitable for college use, so that by 1964, when Kurtz became an associate professor of mathematics, they had a fully operational BASIC system; by 1969 a sixth version was already in existence. In 1966 Kurtz left Dartmouth to become a Director of the Kiewit Computer Center, and then, in 1975, he became a Director of the Office of Academic Computing; in 1978 he returned to Dartmouth as Professor of Mathematics. He also served on various national committees.[br]Bibliography1964, with J.G.Kemeny, BASIC Instruction Manual: Dartmouth College (for details of the development of BASIC etc.).1968, with J.G.Kemeny "Dartmouth time-sharing", Science 223.Further ReadingR.L.Wexelblat, 1981, History of Programming Languages, London: Academic Press (a more general view of the development of computer languages).KF
