A brief summary was published as the "Effect of Light on Selenium during the passage of an Electric Current" in the 20 February 1873 issue of Nature . In 2017 his work on selenium was recognized with a Technology and Engineering Emmy Award for " Concept of Opto-Electric Transduction " by

EASAMS Ltd was an independent company within General Electric Company (GEC), founded in 1962 to provide services in system design , operational research and project management . In the 1990s EASAMS became part of Marconi Electronic Systems before losing its identity. The following computer models were produced: Willoughby Smith Willoughby Smith (6 April 1828, in Great Yarmouth , Norfolk – 17 July 1891, in Eastbourne , Sussex )
88-758: The BAC TSR-2 . Developments for the cancelled TSR-2 were later incorporated into multirole combat aircraft (MRCA), which finally became the Panavia Tornado . EASAMS senior management was highly conservative, and a number of innovative engineers working on 'private venture' projects such as Hierarchical Object-Oriented Design (HOOD) and Ada language development left to form their own firms. These included Admiral Computing (which later merged with Logica ), Systems Designers Ltd (which later merged with Electronic Data Systems (EDS), and subsequently became part of Hewlett-Packard (HP)) and Software Sciences (later
110-641: The National Academy of Television Arts and Sciences . As the Emmy can be presented only to living persons, the award was made to three organizations (or their successors) with which his work was associated: Telcon (now Alcatel-Lucent), the Society of Telegraph Engineers (now the Institution of Engineering and Technology , IET) and Siemens. Willoughby was the son of William Smith, a sailor, and his wife, Harriot. He married Ann, daughter of William Sanders,
132-602: The Navy. In 1898, the company moved out of London to a new site in Lewisham , then located in Kent . One of the main products at this site was naval gunnery tables, which were mechanical analog computers, which were manufactured until after World War II . Aircraft instruments became an important product line with the development of heavier than air flight; instruments such as tachometers and altimeters were vital in aviation. In 1916,
154-491: The business to his wife Susan. In 1876, the company expanded to a new factory to manufacture telegraph equipment and instruments for the British Admiralty. There was increased demand for electrical switchboards for the growing electric power industry. Susan Elliott became partners with Willoughby Smith , who had significant expertise in telegraphic instruments; she was the last Elliott family member associated with
176-476: The company changed its name to Elliott Automation Ltd. By 1966, Elliott Automation had started their own semiconductor factory at Glenrothes , Scotland. The company had about 35,000 employees. In 1967 Elliott Automation was merged into English Electric . Elliott Automation (as it had become) merged with English Electric in 1967. The data processing computer part of the company was merged with International Computers and Tabulators (ICT) in 1968; this marriage
198-441: The company changed its name to Elliott Brothers (London), Limited. In 1920, Siemens Brothers started purchasing shares of the company. The end of Admiralty contracts after the war severely affected Elliott Brothers, which had not been involved in radar and electronics technology during the war. Siemens Brothers had sold their interest in the company, and a new director, Leon Bagrit , was instrumental in rebuilding and redirecting
220-551: The company established an integrated circuit design and manufacturing facility in Glenrothes , Scotland , followed by a metal–oxide semiconductor (MOS) research laboratory. In 1967, Elliott Automation was merged into the English Electric company and in 1968 the computer part of the company became part of International Computers Limited (ICL). William Elliott was born in either 1780 or 1781 and apprenticed to
242-461: The company when she died in 1880. Smith in turn brought his sons in to manage the company operations. In 1893, the instrument making company Theilers joined Elliotts, with W. O. Smith and G. K. E. Elphinstone as managers. Elphinstone had useful connections with the British Navy. He was knighted for his contributions at Elliotts during World War I, with developments in gunnery instruments for

#1732798123702264-569: The firm into new areas. In 1946, John Flavell Coales founded the Research Laboratories of Elliott Brothers at Borehamwood . This laboratory was the site of development of radar systems for the Government, and in 1947 produced a stored-program digital computer. By 1950 the laboratory had a staff of 450, and had developed the commercial Elliott 401 computer. In 1953, Elliott formed an "Aviation Division" at Borehamwood. In 1957,
286-559: The instrument maker William Blackwell in 1795. In 1804, Elliott began his own company to make drawing instruments, scales, and scientific instruments. In 1850, his two sons Charles and Fredrick joined his business. The company prospered, and manufactured a range of surveying, navigational, and other instruments. William Elliott died in 1853. In the 1850s the company began manufacturing electrical instruments, which were used by researchers such as James Clerk Maxwell and others. Charles Elliott retired in 1865, and when Frederick died in 1873 he left
308-416: The late 1990s. The agreement which governed the split of computer technologies between the two companies disallowed ICT from developing real-time computer systems and disallowed Elliott Automation from developing data processing computer systems for a few years after the split. The remainder of Elliott Automation which produced aircraft instruments and control systems, was retained by English Electric. EASAMS

352-410: The manufacture and laying of 30 miles of underwater telegraph wire from Dover to Calais . Though the first cable failed almost immediately, another laid the following year was a success and over the following decades, Smith and the company he worked for were involved with many other underwater telegraph cable projects. In 1866, Smith developed a method for continually testing an underwater cable as it

It evolved its proprietary EMPRENT , an early program evaluation and review technique (PERT) planning system used in building North Sea oil platforms , and for
396-493: Was an English electrical engineer who discovered the photoconductivity of the element selenium . This discovery led to the invention of photoelectric cells , including those used in the earliest television systems. In 1848, he began working for the Gutta Percha Company , London where he developed iron and copper wires insulated with gutta-percha to be used for telegraph wires. In 1850, Smith superintended
418-515: Was an early computer company of the 1950s and 1960s in the United Kingdom. It traced its descent from a firm of instrument makers founded by William Elliott in London around 1804. The research laboratories were originally set up in 1946 at Borehamwood and the first Elliott 152 computer appeared in 1950. In its day the company was very influential. The computer scientist Bobby Hersom
440-586: Was an employee from 1953 to 1954, and Sir Tony Hoare was an employee there from August 1960 to 1968. He wrote an ALGOL 60 compiler for the Elliott 803 . He also worked on an operating system for the new Elliott 503 Mark II computer. The founder of the UK's first software house , Dina St Johnston , had her first programming job there from 1953 to 1958, and John Lansdown pioneered the use of computers as an aid to planning on an Elliott 803 computer in 1963. In 1966
462-417: Was being laid. For his test circuit, he needed a semi-conducting material with a high resistance and selected selenium rods for this purpose. The selenium seemed to do the job properly, except in actual use, the device gave inconsistent results. Upon investigation, it was discovered that the conductivity of the selenium rods increased significantly when exposed to strong light. Smith described his research in

#1732798123702484-480: Was forced by the British Government, who believed that the UK required a strong national computer company. The combined company was called International Computers Limited (ICL).
