1 Forrester, George
[br]b. 1780/1 Scotlandd. after 1841[br]Scottish locomotive builder and technical innovator.[br]George Forrester \& Co. built locomotives at the Vauxhall Foundry, Liverpool, between 1834 and c.1847. The first locomotives built by them, in 1834, were three for the Dublin \& Kingstown Railway and one for the Liverpool \& Manchester Railway; they were the first locomotives to have outside horizontal cylinders and the first to have four fixed eccentrics to operate the valves, in place of two loose eccentrics. Two locomotives built by Forrester in 1835 for the Dublin \& Kingstown Railway were the first tank locomotives to run regularly on a public railway, and two more supplied in 1836 to the London \& Greenwich Railway were the first such locomotives in England. Little appears to be known about Forrester himself. In the 1841 census his profession is shown as "civil engineer, residence 1 Lord Nelson Street". Directories for Liverpool, contemporary with Forrester \& Co.'s locomotive building period, describe the firm variously as engineers, iron founders and boilermakers, located at (successively) 234,224 and 40 Vauxhall Road. Works Manager until 1840 was Alexander Allan, who subsequently used the experience he had gained with Forrester in the design of his "Crewe Type" outside-cylinder locomotive, which became widely used.[br]Further ReadingE.L.Ahrons, 1927, The British Steam Railway Locomotive 1825–1925, The Locomotive Publishing Co., pp. 29, 43, 50 and 83.J.Lowe, 1975, British Steam Locomotive Builders, Cambridge: Goose \& Son.R.H.G.Thomas, 1986, London's First Railway: The London \& Greenwich, B.T.Batsford, p. 176.PJGR -
2 Forrester, Jay Wright
SUBJECT AREA: Electronics and information technology[br]b. 14 July 1918 Anselmo, Nebraska, USA[br]American electrical engineer and management expert who invented the magnetic-core random access memory used in most early digital computers.[br]Born on a cattle ranch, Forrester obtained a BSc in electrical engineering at the University of Nebraska in 1939 and his MSc at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts, where he remained to teach and carry out research. Becoming interested in computing, he established the Digital Computer Laboratory at MIT in 1945 and became involved in the construction of Whirlwind I, an early general-purpose computer completed in March 1951 and used for flight-simulation by the US Army Air Force. Finding the linear memories then available for storing data a major limiting factor in the speed at which computers were able to operate, he developed a three-dimensional store based on the binary switching of the state of small magnetic cores that could be addressed and switched by a matrix of wires carrying pulses of current. The machine used parallel synchronous fixed-point computing, with fifteen binary digits and a plus sign, i.e. 16 bits in all, and contained 5,000 vacuum tubes, eleven semiconductors and a 2 MHz clock for the arithmetic logic unit. It occupied a two-storey building and consumed 150kW of electricity. From his experience with the development and use of computers, he came to realize their great potential for the simulation and modelling of real situations and hence for the solution of a variety of management problems, using data communications and the technique now known as interactive graphics. His later career was therefore in this field, first at the MIT Lincoln Laboratory in Lexington, Massachusetts (1951) and subsequently (from 1956) as Professor at the Sloan School of Management at the Massachusetts Institute of Technology.[br]Principal Honours and DistinctionsNational Academy of Engineering 1967.

3 Pousadas
Government-sponsored inns similar to Spain's paradores. In 1942, Portugal initiated a system of state-run inns, pousadas, housed in restored, historic castles, convents, manor houses, palaces, and monasteries. By 2008, this system included more than forty pousadas or inns in every region of the country and in the Azores Islands. Recently, the government-owned system came under the management of Pestana Hotels, a private group. Such tourist habitations with reasonable nightly rates have been in high demand and feature antique, period furnishings and restaurants with Portuguese cuisine. Most are located in or near towns or cities with other historic places and sites.

CruzThe history of displaying nativity scenes, portraying the birth of Christ in a manger, goes back in Catholic tradition at least to Christmas 1223, when Saint Francis of Assisi arranged a nativity scene with live figures in a town in Italy, but scholars confirm that this Christmas tradition in the arts is much older than the 13th century. Figurines depicting the Holy Family in nativity scenes were made of various materials, including wood, precious metals, and ceramics. In Portugal, an artistic tradition of making and displaying presepios in or near churches, chapels, and cathedrals reached its zenith in the arts in the 18th century during the long reign of King João V (1706-50). In the Baroque era, an artistic tradition that arrived somewhat late in Portugal, the most celebrated and talented of the nativity scene artists was the 18th-century Coimbra sculptor, Joaquim Machado de Castro (1751/2-1822), but there were other great artists in this field as well. The 18th century's most celebrated sculptor, Machado de Castro created the famous equestrian bronze statue of King José I, in Commerce Square, Lisbon. During the time of Machado de Castro's time, the ceramic nativity scene comprised of large figures and elaborate scenery became a cult, and many nativity scenes were made.Today, many of these historic artistic creations, with a strong basis in Christian tradition, can be viewed in various Portuguese museums, palaces, and churches. Some of the most famous larger nativity scenes, including those lovingly created by Machado de Castro of Coimbra, are found on display at Christmas and other times in the Estrela Basilica, the Palace of Necessidades, the Palace of Queluz, the Church of Madre de Deus, the Cathedral in Lisbon, and in other religious or museum buildings in Lisbon, Oporto, and other towns in Portugal. The ceramic nativity scene is not only sacred art but also evolved as folk and now tourist art, as Portuguese nativity scenes, with figures smaller than in the Baroque treasures on display of Machado de Castro, are for sale in a number of stores, as well as in some churches in Lisbon, Oporto, Estremoz, Évora, and other cities. The styles of the nativity scenes vary by region, by town, and by artist, and many include not only sacred figures of the story of the birth of Christ but also traditional, rural, folk figurines depicting Portuguese rural occupations from the 18th and 19th century, as well as figures from stories from the Bible. The ceramic materials of which these figures of varying sizes are made include variations of terracotta. -

5 Burks, Arthur Walter
SUBJECT AREA: Electronics and information technology[br]b. 13 October 1915 Duluth, Minnesota, USA[br]American engineer involved in the development of the ENIAC and Whirlwind computers.[br]After obtaining his AB degree from De Pere University, Wisconsin (1937), and his AM and PhD from the University of Michigan (1938 and 1941, respectively), Burks carried out research at the Moore School of Engineering, University of Pennsylvania, during the Second World War, and at the same time taught philosophy in another department. There, with Herman Goldstine, he was involved in the construction of ENIAC (the Electronic Numerical Integrator and Computer).In 1946 he took a post as Assistant Professor of Engineering at Michigan University, and subsequently became Associate Professor (1948) and Full Professor (1954). Between 1946 and 1948 he was also associated with the computer activities of John von Neumann at the Institute of Advanced Studies, Princeton, and was involved in the development of the Whirlwind I computer (the first stored-program computer) by Jay Forrester at the Massachusetts Institute of Technology. From 1948 until 1954 he was a consultant for the Burroughs Corporation and also contributed to the Oak Ridge computer ORACLE. He was Chairman of the Michigan University Department of Communications Science in 1967–71 and at various times was Visiting Professor at Harvard University and the universities of Illinois and Stanford. In 1975 he became Editor of the Journal of Computer and System Sciences.[br]Bibliography1946. "Super electronic computing machine", Electronics Industry 62.1947.

7 Laird, John
SUBJECT AREA: Ports and shipping[br]b. 1805 (?) Greenock, Scotlandd. 26 October 1874 Birkenhead, England[br]Scottish pioneer of large-scale iron shipbuilding.[br]When only 5 years old, Laird travelled with his family to Merseyside, where his father William Laird was setting up a ship-repair yard. Fourteen years later his father established the Birkenhead Ironworks for ship and engine repairs, which in later years was to achieve great things with John Laird at the helm. John Laird trained as a solicitor, but instead of going into practice he joined the family business. Between 1829 and 1832 they built three iron barges for inland use in Ireland; this form of construction had become less of a novelty and followed the example set by Thomas Wilson in 1819, but Laird was fired with enthusiasm for this mode of construction. New iron ships followed in rapid succession, with two of especial note: the paddle steamer Lady Lansdown of 1833, which was dismantled and later re-erected on the river Shannon, becoming one of Britain's first "knock-down" contracts; and the early steamer Robert F.Stockton, which had a double Ericsson screw propeller and the first iron transverse watertight bulkheads. With the good name of the shipyard secure, they received orders from MacGregor Laird (John Laird's younger brother) for iron ships for the West African trade. This African connection was to grow and the yard's products were to include the Ma Roberts for Dr David Livingstone. Being of steel and with constant groundings on African rivers, this craft only lasted 18 months in steady operation. In 1858 a new yard dedicated to iron construction was opened at Monk's Ferry. In 1861 John Laird was returned as the first Member of Parliament for Birkenhead and his sons took over the day-to-day affairs of the business. Laird was to suffer acute embarrassment by questions at Westminster over the building in the Birkenhead Works of the United States Confederate raider Alabama in 1862. In 1874 he suffered serious injuries in a riding accident; his health declined and he died later that year.[br]Bibliography1858, with Fairbairn, Forrester, Lang and Sea-ward, Steam Navigation, Vessels of Iron and Wood, the Steam Engine, etc. 2 vols, London: Weale.FMW -

10 Wilkes, Maurice Vincent
SUBJECT AREA: Electronics and information technology[br]b. 26 June 1913 Stourbridge, Worcestershire, England[br]English physicist who was jointly responsible for the construction of the EDS AC computer.[br]Educated at King Edward VI Grammar School, Stourbridge, where he began to make radio sets and read Wireless World, Wilkes went to St John's College, Cambridge, in 1931, graduating as a Wrangler in the Mathematical Tripos in 1934. He then carried out research at the Cavendish Laboratory, becoming a demonstrator in 1937. During the Second World War he worked on radar, differential analysers and operational research at the Bawdsey Research Station and other air-defence establishments. In 1945 he returned to Cambridge as a lecturer and as Acting Director of the Mathematical (later Computer) Laboratory, serving as Director from 1946 to 1970.During the late 1940s, following visits to the USA for computer courses and to see the ENIAC computer, with the collaboration of colleagues he constructed the Cambridge University digital computer EDSAC (for Electronic Delay Storage Automatic Computer), using ultrasonic delay lines for data storage. In the mid-1950s a second machine, EDSAC2, was constructed using a magnetic-core memory. In 1965 he became Professor of Computer Technology. After retirement he worked for the Digital Electronic Corporation (DEC) from 1981 to 1986, serving also as Adjunct Professor of Computer Science and Electrical Engineering at the Massachusetts Institute of Technology from 1981 to 1985. In 1990 he became a research strategy consultant to the Olivetti Research Directorate.[br]Principal Honours and DistinctionsFRS 1956. First President, British Computer Society 1957–60.
