Mansfield, the son of a country clergyman, was educated privately at first, then at Winchester College and at Cambridge; ill health, which dogged his early years, delayed his graduation until 1846. He was first inclined to medicine, but after settling in London, chemistry seemed to him to offer the true basis of the grand scheme of knowledge he aimed to establish. After completing the chemistry course at the Royal College of Chemistry in London, he followed the suggestion of its first director, A.W.von Hofmann, of investigating the chemistry of coal tar. This work led to a result of great importance for industry by demonstrating the valuable substances that could be extracted from coal tar. Mansfield obtained pure benzene, and toluene by a process for which he was granted a patent in 1848 and published in the Chemical Society's journal the same year The following year he published a pamphlet on the applications of benzene.

Blessed with a private income, Mansfield had no need to support himself by following a regular profession. He was therefore able to spread his brilliant talents in several directions instead of confining them to a single interest. During the period of unrest in 1848, he engaged in social work with a particular concern to improve sanitation. In 1850, a description of a balloon machine in Paris led him to study aeronautics for a while, which bore fruit in an influential book, Aerial Navigation (London, 1851). He then visited Paraguay, making a characteristically thorough and illuminating study of conditions there. Upon his return to London in 1853, Mansfield resumed his chemical studies, especially on salts. He published his results in 1855 as Theory of Salts, his most important contribution to chemical theory.

Mansfield was in the process of preparing specimens of benzene for the Paris Exhibition of 1855 when a naphtha still overflowed and caught fire. In carrying it to a place of safety, Mansfield sustained injuries which unfortunately proved fatal.

Lovelock was brought up in Brixton in modest circumstances. At the age of 4 he was given a toy electrical set, which first turned his attention towards the study of science. From the Strand School, Brixton, he went on to the universities of Manchester and London, and after graduating in science, in 1941 he joined the National Institute for Medical Research, Mill Hill, as a staff scientist, remaining there for twenty years. During the early 1950s, he and his colleagues were engaged in research into freezing live animals and bringing them back to life by heating: Lovelock was struck by the intense pain this process caused the animals, and he sought a more humane method. He tried diathermy or internal heating through the effect of a continuous wave magnetron borrowed from the Navy. He found that the animals were brought back to life painlessly, and impressed with his success he tried baking a potato for his lunch in the apparatus and found that it cooked amazingly quickly compared with the one hour normally needed in an ordinary oven. Lovelock had invented the microwave oven, but its commercial possibilities were not at first realized.

In the late 1950s he invented the electron capture detector, which proved to be more sensitive than any other analytical equipment in detecting and measuring toxic substances. The apparatus therefore had obvious uses in testing the quality of the environment and so offered a tremendous boost to the "green" movement. In 1961 he was invited to joint the US National Aeronautics and Space Administration (NASA) to employ the apparatus in an attempt to detect life in space.

In the early 1970s Lovelock relinquished his biological work in order to devote his attention to philosophical matters, specifically to develop his theory of the Universe, now widely celebrated as the "Gaia theory". In this controversial theory, Lovelock regards our planet and all its living beings, including humans, as a single living organism.

At the age of 19, Phillips developed an interest in flight and constructed models with lightweight engines. He spent a large amount of time and money over many years, carrying out practical research into the science of aerodynamics. In the early 1880s he built a wind tunnel with a working section of 15 in. by 10 in. (38 cm by 25 cm). Air was sucked through the working section by an adaptation of the steam injector used in boilers and invented by Henry Giffard, the airship pioneer. Phillips tested aerofoils based on the cross-section of bird's wings, with a greater curvature on the upper surface than the lower. He measured the lift and drag and showed that the major component of lift came from suction on the upper surface, rather than pressure on the lower. He took out patents for his aerofoil sections in 1884 and 1891. In addition to his wind-tunnel test, Phillips tested his wing sections on a whirling arm, as used earlier by Cayley, Wenham and Lilienthal. After a series of tests using an arm of 15 ft (4.57 m) radius, Phillips built a massive whirling arm driven by a steam engine. His test pieces were mounted on the end of the arm, which had a radius of 50 ft (15.24 m), giving them a linear speed of 70 mph (113 km/h). By 1893 Phillips was ready to put his theories to a more practical test, so he built a large model aircraft driven by a steam engine and tethered to run round a circular track. It had a wing span of 19 ft (5.79 m), but it had fifty wings, one above the other. These wings were only 10 in. (25 cm) wide and mounted in a frame, so it looked rather like a Venetian blind. At 40 mph (64 km/h) it lifted off the track. In 1904 Phillips built a full-size multi-wing aeroplane with twenty wings which just lifted off the ground but did not fly. He built another multi-wing machine in 1907, this time with four Venetian blind' frames in tandem, giving it two hundred wings! Phillips made a short flight of almost 500 ft (152 m) which could be claimed to be the first powered aeroplane flight in England by an Englishman. He retired from flying at the age of 62.

Stuart's involvement with engines covered a period of less than ten years and was concerned with a means of vaporizing the heavier oils for use in the so-called oil engines. Leaving his native Yorkshire for Bletchley in Buckinghamshire, Stuart worked in his father's business, the Bletchley Iron and Tin Plate works. After finishing grammar school, he worked as an assistant in the Mechanical Engineering Department of the City and Guilds of London Technical College. He also formed a connection with the Finsbury Technical College, where he became acquainted with Professor William Robinson, a distinguished engineer eminent in the field of internal-combustion engines.

Resuming work at Bletchley, Stuart carried out experiments with engines. His first patent was concerned with new methods of vaporizing the fuel, scavenging systems and improvement of speed control. Two further patents, in 1890, specified substantial improvements and formed the basis of later engine designs. In 1891 Stuart joined forces with R.Hornsby and Sons of Grantham, a firm founded in 1815 for the manufacture of machinery and steam engines. Hornsby acquired all rights to Stuart's engine patents, and their superior technical resources ensured substantial improvements to Stuart's early design. The Hornsby-Ackroyd engines, introduced in 1892, were highly successful and found wide acceptance, particularly in agriculture. With failing health, Stuart's interest in his engine work declined, and in 1899 he emigrated to Australia, where in 1903 he became a partner in importing gas engines and gas-producing plants. Following his death in 1927, under the terms of his will he was interred in England; sadly, he also requested that all papers and materials pertaining to his engines be destroyed.

   Architect of world renown, designer of many public buildings, including the Portuguese Pavilion at Lisbon's Expo '98, Portugal's end-of-the-century world's fair. Born in Matosinhos, near Oporto, from an early age Siza was fascinated with the art of drawing, a lifetime's vocation. Trained as an architect at the Faculty of Architecture, University of Oporto, Siza began to win commissions for various public places, including opportunities to design parks, churches, swimming pools, and residences of various kinds. Following early work in sculpture and watercolor, he devoted his professional efforts solely to creating a new architecture, under the influence of Oporto instructors as well as foreign architects, including the work of the revolutionary Le Corbusier of France. Among his more emblematic, minimalist works is the Church of Marco de Canavezes. The recipient of the most sought-after architectural prizes from various countries, and the architect of Expo '98's impressive Portuguese Pavilion, Siza's greatest professional honor to date is the equivalent of a Nobel Prize in architecture, the coveted Pritzker Prize, from the Hyatt Foundation, in Chicago.

Mylne was the eldest son of Thomas Mylne, Surveyor to the City of Edinburgh. Little is known of his early education. In 1754, at the age of 21, he left Edinburgh by sea and journeyed to Rome, where he attended the Academy of St Luke. There he received the first prize for architecture. In 1759 he left Rome to travel back to England, where he arrived in time for the competition then going ahead for the design and building of a new bridge across the Thames at Blackfriars. Against 68 other competitors, Mylne won the competition; the work took some ten years to complete.

In 1760 he was appointed Engineer and Architect to the City of London, and in 1767 Joint Engineer to the New River Company together with Henry Mill, who died within a few years to leave Mylne to become Chief Engineer in 1770. Thus for the next forty years he was in charge of all the works for the New River Company between Clerkenwell and Ware, the opposite ends of London's main water supply. By 1767 he had also been appointed to a number of other important posts, which included Surveyor to Canterbury Cathedral and St Paul's Cathedral. In addition to undertaking his responsibilities for these great public buildings, he designed many private houses and villas all over the country, including several buildings for the Duke of Argyll on the Inverary Castle estate.

Mylne was also responsible for the design of a great number of bridges, waterworks and other civil engineering works throughout Britain. Called in to advise on the Norwich city waterworks, he fell out with Joseph Bramah in a somewhat spectacular dispute.

For much of his life Mylne lived at the Water House at the New River Head at Islington, from which he could direct much of the work on that waterway that came under his supervision. He also had residences in New Bridge Street and, as Clerk of Works, at Greenwich Hospital. Towards the end of his life he built himself a small house at Amwell, a country retreat at the outer end of the New River. He kept a diary from 1762 to 1810 which includes only brief memoranda but which shows a remarkable diligence in travelling all over the country by stagecoach and by postchaise. He was a freemason, as were many of his family; he married Mary Home on 10 September 1770, with whom he had ten children, four of whom survived into adulthood.

Zworykin studied engineering at the Institute of Technology in St Petersburg under Boris Rosing, assisting the latter with his early experiments with television. After graduating in 1912, he spent a time doing X-ray research at the Collège de France in Paris before returning to join the Russian Marconi Company, initially in St Petersburg and then in Moscow. On the outbreak of war in 1917, he joined the Russian Army Signal Corps, but when the war ended in the chaos of the Revolution he set off on his travels, ending up in the USA, where he joined the Westinghouse Corporation. There, in 1923, he filed the first of many patents for a complete system of electronic television, including one for an all-electronic scanning pick-up tube that he called the iconoscope. In 1924 he became a US citizen and invented the kinescope, a hard-vacuum cathode ray tube (CRT) for the display of television pictures, and the following year he patented a camera tube with a mosaic of photoelectric elements and gave a demonstration of still-picture TV. In 1926 he was awarded a PhD by the University of Pittsburgh and in 1928 he was granted a patent for a colour TV system.

In 1929 he embarked on a tour of Europe to study TV developments; on his return he joined the Radio Corporation of America (RCA) as Director of the Electronics Research Group, first at Camden and then Princeton, New Jersey. Securing a budget to develop an improved CRT picture tube, he soon produced a kinescope with a hard vacuum, an indirectly heated cathode, a signal-modulation grid and electrostatic focusing. In 1933 an improved iconoscope camera tube was produced, and under his direction RCA went on to produce other improved types of camera tube, including the image iconoscope, the orthicon and image orthicon and the vidicon. The secondary-emission effect used in many of these tubes was also used in a scintillation radiation counter. In 1941 he was responsible for the development of the first industrial electron microscope, but for most of the Second World War he directed work concerned with radar, aircraft fire-control and TV-guided missiles.

After the war he worked for a time on high-speed memories and medical electronics, becoming Vice-President and Technical Consultant in 1947. He "retired" from RCA and was made an honorary vice-president in 1954, but he retained an office and continued to work there almost up until his death; he also served as Director of the Rockefeller Institute for Medical Research from 1954 until 1962.

In 1909 he entered the Moscow Higher Technical School and became a pupil of Nikolai Zhukovsky, who was known as "the father of Russian aviation". Graduating in 1918, he helped Zhukovsky to set up the Zhukovsky Central Aerohydrodynamic Institute and was made Assistant Director. He was appointed Head of the Institute's Design Department in 1922: his work was concentrated on wind tunnels and gliders, but later included aerodynamic calculations and the construction of all-metal aircraft. His first significant design project was the twin-engined Ant-29 fighter prototype, which appeared in the early 1930s and eventually entered service as the SB-2. However, Tupolev and his wife fell victim to Stalin's purges in 1937: she was sent to a labour camp and he was imprisoned, but in 1943 both were rehabilitated and Tupolev was able to resume his design work. He devoted his attention to long-range strategic bombers, the first of these being the Tu-4, a copy of the US B-29, followed by the Tu-70 bomber. He also designed the Tu-104 airliner, and in 1967 he produced the world's first supersonic airliner, the Tu-144. Tupolev also became interested in fast-attack naval craft and designed a number of torpedo launches, and he rose to the rank of Lieutenant-General in the Soviet air force's Engineering and Technical Service.

After arriving in the USA in 1870 and becoming an American citizen, Berliner worked as a dry-goods clerk in Washington, DC, and for a period studied electricity at Cooper Union for the Advancement of Science and Art, New York. He invented an improved microphone and set up his own experimental laboratory in Washington, DC. He developed a microphone for telephone use and sold the rights to the Bell Telephone Company. Subsequently he was put in charge of their laboratory, remaining in that position for eight years. In 1881 Berliner, with his brothers Joseph and Jacob, founded the J.Berliner Telephonfabrik in Hanover, the first factory in Europe specializing in telephone equipment.

Inspired by the development work performed by T.A. Edison and in the Volta Laboratory (see C.S. Tainter), he analysed the existing processes for recording and reproducing sound and in 1887 developed a process for transferring lateral undulations scratched in soot into an etched groove that would make a needle and diaphragm vibrate. Using what may be regarded as a combination of the Phonautograph of Léon Scott de Martinville and the photo-engraving suggested by Charles Cros, in May 1887 he thus demonstrated the practicability of the laterally recorded groove. He termed the apparatus "Gramophone". In November 1887 he applied the principle to a glass disc and obtained an inwardly spiralling, modulated groove in copper and zinc. In March 1888 he took the radical step of scratching the lateral vibrations directly onto a rotating zinc disc, the surface of which was protected, and the subsequent etching created the groove. Using well-known principles of printing-plate manufacture, he developed processes for duplication by making a negative mould from which positive copies could be pressed in a thermoplastic compound. Toy gramophones were manufactured in Germany from 1889 and from 1892–3 Berliner manufactured both records and gramophones in the USA. The gramophones were hand-cranked at first, but from 1896 were based on a new design by E.R. Johnson. In 1897–8 Berliner spread his activities to England and Germany, setting up a European pressing plant in the telephone factory in Hanover, and in 1899 a Canadian company was formed. Various court cases over patents removed Berliner from direct running of the reconstructed companies, but he retained a major economic interest in E.R. Johnson's Victor Talking Machine Company. In later years Berliner became interested in aeronautics, in particular the autogiro principle. Applied acoustics was a continued interest, and a tile for controlling the acoustics of large halls was successfully developed in the 1920s.

Bury was the earliest engineer to build locomotives distinctively different from those developed by Robert Stephenson yet successful in mainline passenger service. A Liverpool sawmill owner, he set up as a locomotive manufacturer while the Liverpool \& Manchester Railway was under construction and, after experiments, completed the four-wheeled locomotive Liverpool in 1831. It included features that were to be typical of his designs: a firebox in the form of a vertical cylinder with a dome-shaped top and the front flattened to receive the tubes, and inside frames built up from wrought-iron bars. In 1838 Bury was appointed to supply and maintain the locomotives for the London \& Birmingham Railway (L \& BR), then under construction by Robert Stephenson, on the grounds that the latter should not also provide its locomotives. For several years the L \& BR used Bury locomotives exclusively, and they were also used on several other early main lines. Following export to the USA, their bar frames became an enduring feature of locomotive design in that country. Bury claimed, with justification, that his locomotives were economical in maintenance and fuel: the shape of the firebox promoted rapid circulation of water. His locomotives were well built, but some of their features precluded enlargement of the design to produce more powerful locomotives and within a few years they were outclassed.

Dagron studied chemistry, but little else is known of his early career. He was the proprietor of a Paris shop selling stationery and office equipment in 1860, when he proposed making microscopic photographs mounted in jewellery. Dagron went on to produce examples using equipment constructed by the optician Debozcq. In 1864 Dagron became one of the celebrities of the day when he recorded 450 portraits on a single photograph that measured 1 mm³. The image was viewed by means of a tiny magnifying lens popularly known as a "Stanhope" after its supposed inventor, the English Lord Charles Stanhope. The great demand for Stanhoped jewellery soon allowed Dagron to build a factory for its manufacture. Dagron's main claim to fame rests on his work during the Franco-Prussian War. At the siege of Paris, Dagron was ballooned out of the city to organize a carrier-pigeon communication service. Thousands of microphotographed dispatches could be carried by a single pigeon, and Dagron set up a regular service between Paris and Tours. In Paris the messages from the outside world were enlarged and projected onto a white wall and transcribed by a team of clerks. After the war, Dagron dabbled in aerial photography from balloons, but his interest in microphotography continued until his death in 1900.

Griffith was very much a "boffin", for he was a quiet, thoughtful man who shunned public appearances, yet he produced many revolutionary ideas. During the First World War he worked at the Royal Aircraft Factory, Farnborough, where he carried out research into structural analysis. Because of his use of soap films in solving torsion problems, he was nicknamed "Soap-bubble".

During the 1920s Griffith carried out research into gas-turbine design at the Royal Aircraft Establishment (RAE; as the Royal Aircraft Factory had become). In 1929 he made proposals for a gas turbine driving a propeller (a turboprop), but the idea was shelved. In the 1930s he was head of the Engine Department of the RAE and developed multi-stage axial compressors, which were later used in jet engines. This work attracted the attention of E.W. (later Lord) Hives of Rolls-Royce who persuaded Griffith to join Rolls-Royce in 1939. His first major project was a "contra-flow" jet engine, which was a good idea but a practical failure. However, Griffith's axial-flow compressor experience played an important part in the success of Rolls-Royce jet engines from the Avon onwards. He also proposed the bypass principle used for the Conway.

Griffith experimented with suction to control the boundary layer on wings, but his main interest in the 1950s centred on vertical-take-off and -landing aircraft. He developed the remarkable "flying bedstead", which consisted of a framework (the bedstead) in which two jet engines were mounted with their jets pointing downwards, thus lifting the machine vertically. It first flew in 1954 and provided much valuable data. The Short SC1 aircraft followed, with four small jets providing lift for vertical take-off and one conventional jet to provide forward propulsion. This flew successfully in the late 1950s and early 1960s. Griffith proposed an airliner with lifting engines, but the weight of the lifting engines when not in use would have been a serious handicap. He retired in 1960.

From his early years, Haynes was a practising Presbyterian and an active prohibitionist. He graduated in 1881 at Worcester, Massachusetts, and a spell of teaching in his home town was interrupted in 1884–5 while he attended the Johns Hopkins University in Baltimore. In 1886 he became permanently diverted by the discovery of natural gas in Portland. He was soon appointed Superintendent of the local gas undertaking, and then in 1890 he was hired by the Indiana Natural Gas \& Oil Company. While continuing his gas-company employment until 1901, Haynes conducted numerous metallurgical experiments. He also designed an automobile: this led to the establishment of the Haynes- Apperson Company at Kokomo as one of the earliest motor-car makers in North America. From 1905 the firm traded as the Haynes Automobile Company, and before its bankruptcy in 1924 it produced more than 50,000 cars. After 1905, Haynes found the first "Stellite" alloys of cobalt and chromium, and in 1910 he was publicizing the patented material. He then discovered the valuable hardening effect of tungsten, and in 1912 began applying the "improved" Stellite to cutting tools. Three years later, the Haynes Stellite Company was incorporated, with Haynes as President, to work the patents. It was largely from this source that Haynes became a millionaire in 1920. In April 1912, Haynes's attempt to patent the use of chromium with iron to render the product rustless was unsuccessful. However, he re-applied for a US patent on 12 March 1915 and, although this was initially rejected, he persevered and finally obtained recognition of his modified claim. The American Stainless Steel Company licensed the patents of Brearley and Haynes jointly in the USA until the 1930s.

At the age of 19 Marey went to Paris to study medicine, becoming particularly interested in the problems of the circulation of the blood. In an early communication to the Académie des Sciences he described a much improved device for recording the pulse, the sphygmograph, in which the beats were recorded on a smoked plate. Most of his subsequent work was concerned with methods of recording movement: to study the movement of the horse, he used pneumatic sensors on each hoof to record traces on a smoked drum; this device became known as the Marey recording tambour. His attempts to study the wing movements of a bird in flight in the same way met with limited success since the recording system interfered with free movement. Reading in 1878 of Muybridge's work in America using sequence photography to study animal movement, Marey considered the use of photography himself. In 1882 he developed an idea first used by the astronomer Janssen: a camera in which a series of exposures could be made on a circular photographic plate. Marey's "photographic gun" was rifle shaped and could expose twelve pictures in approximately one second on a circular plate. With this device he was able to study wing movements of birds in free flight. The camera was limited in that it could record only a small number of images, and in the summer of 1882 he developed a new camera, when the French government gave him a grant to set up a physiological research station on land provided by the Parisian authorities near the Porte d'Auteuil. The new design used a fixed plate, on which a series of images were recorded through a rotating shutter. Looking rather like the results provided by a modern stroboscope flash device, the images were partially superimposed if the subject was slow moving, or separated if it was fast. His human subjects were dressed all in white and moved against a black background. An alternative was to dress the subject in black, with highly reflective strips and points along limbs and at joints, to produce a graphic record of the relationships of the parts of the body during action. A one-second-sweep timing clock was included in the scene to enable the precise interval between exposures to be assessed. The fixed-plate cameras were used with considerable success, but the number of individual records on each plate was still limited. With the appearance of Eastman's Kodak roll-film camera in France in September 1888, Marey designed a new camera to use the long rolls of paper film. He described the new apparatus to the Académie des Sciences on 8 October 1888, and three weeks later showed a band of images taken with it at the rate of 20 per second. This camera and its subsequent improvements were the first true cinematographic cameras. The arrival of Eastman's celluloid film late in 1889 made Marey's camera even more practical, and for over a decade the Physiological Research Station made hundreds of sequence studies of animals and humans in motion, at rates of up to 100 pictures per second. Marey pioneered the scientific study of movement using film cameras, introducing techniques of time-lapse, frame-by-frame and slow-motion analysis, macro-and micro-cinematography, superimposed timing clocks, studies of airflow using smoke streams, and other methods still in use in the 1990s. Appointed Professor of Natural History at the Collège de France in 1870, he headed the Institut Marey founded in 1898 to continue these studies. After Marey's death in 1904, the research continued under the direction of his associate Lucien Bull, who developed many new techniques, notably ultra-high-speed cinematography.

Neri entered the Church and by 1601 was a priest in the household of Alamanno Bertolini in Florence. There he met the Portuguese Sir Emanuel Ximenes, with whom he shared an interest in chemistry. The two later corresponded and the twenty-seven letters extant from Ximenes, who was living in Antwerp, are the main source of information about Neri's life. At the same time, Neri was working as a craftsman in the Medici glasshouse in Florence and then in their works at Pisa. These glasshouses had been flourishing since the fifteenth century with the help of Muranese glassmakers imported from Venice. Ximenes persuaded Neri to spend some time with the glassmakers in Antwerp, probably from 1603/4, for the correspondence breaks off at that point. A final letter in March 1611 refers to Neri's recent return to Florence. In the following year, Neri published the work by which he is known, the L'arte vetraria, the first general treatise on glassmaking. Neri's plan for a further book describing his chemical and medical experiments was thwarted by his early death. L'arte belongs to the medieval tradition of manuscript recipe books. It is divided into seven books, the first being the most interesting, dealing with the materials of glassmaking and their mixing and melting to form crystal and other colourless glasses. Other sections deal with coloured glasses and the making of enamels for goldsmiths' use. Although it was noted by Galileo Galilei (1564–1642), the book made little impression for half a century, the second edition not appearing until 1661. The first Venice edition came out two years later, with a second in 1678. Due to a decline in scientific activity in Italy at this time, L'arte had more influence elsewhere in Europe, especially England, Holland and France. It began to make a real impact with the appearance in 1662 of the English translation by Christopher Merrett (1614–95), physician, naturalist and founder member of the Royal Society. This edition included Merrett's annotations, descriptions of the tools used by English glassmakers and a translation of Agricola's short account of glassmaking in his De re metallica of 1556. Later translations were based on the Merrett translation rather than the Italian original. Ravenscroft probably used Neri's account of lead glass as a starting point for his own researches in the 1670s.

Stibitz spent his early years in Dayton, Ohio, and obtained his first degree at Denison University, Granville, Ohio, his MS from Union College, Schenectady, New York, in 1927 and his PhD in mathematical physics from Cornell University, Ithaca, New York, in 1930. After working for a time for General Electric, he joined Bell Laboratories to work on various communications problems. In 1937 he started to experiment at home with telephone relays as the basis of a calculator for addition, multiplication and division. Initially this was based on binary arithmetic, but later he used binary-coded decimal (BCD) and was able to cope with complex numbers. In November 1938 the ideas were officially taken up by Bell Laboratories and, with S.B.Williams as Project Manager, Stibitz built a complex-number computer known as "Complex", or Relay I, which became operational on 8 January 1940.

With the outbreak of the Second World War, he was co-opted to the National Defence Research Council to work on anti-aircraft (AA) gun control, and this led to Bell Laboratories Relay II computer, which was completed in 1943 and which had 500 relays, bi-quinary code and selfchecking of errors. A further computer, Relay III, was used for ballistic simulation of actual AA shell explosions and was followed by more machines before and after Stibitz left Bell after the end of the war. Stibitz then became a computer consultant, involved in particular with the development of the UNIVAC computer by John Mauchly and J.Presper Eckert.

Very little is known of his early life, but he was clearly a skilful and gifted engineer who had received comprehensive practical training, for in 1743 he erected the machinery in the world's first water-powered cotton mill at Northampton on the river Nene. In 1748 he invented a weighing machine for use by turnpike trusts for weighing wagons. Until 1757 he remained in Northampton, mainly surveying enclosures and turnpike roads and making agricultural machinery. He also gained a national reputation for building and installing very successful ventilating equipment (invented by Dr Stephen Hales) in hospitals, prisons and ships, including some ventilators of Yeoman's own design in the Houses of Parliament.

Meanwhile he developed an interest in river improvements, and in 1744 he made his first survey of the River Nene between Thrapston and Northampton; he repeated the survey in 1753 and subsequently gave evidence in parliamentary proceedings in 1756. The following year he was in Gloucestershire surveying the line of the Stroudwater Canal, an operation that he repeated in 1776. Also in 1757, he was appointed Surveyor to the River Ivel Navigation in Bedfordshire. In 1761 he was back on the Nene. During 1762–5 he carried out surveys for the Chelmer \& Blackwater Navigation, although the work was not undertaken for another thirty years. In 1765 he reported on land-drainage improvements for the Kentish Sour. It was at this time that he became associated with John Smeaton in a major survey in 1766 of the river Lea for the Lee Navigation Trustees, having already made some surveys with Joseph Nickalls near Waltham Abbey in 1762. Yeoman modified some of Smeaton's proposals and on 1 July 1767 was officially appointed Surveyor to the Lee Navigation Trustees, a post he retained until 1771. He also advised on the work to create the Stort Navigation, and at the official opening on 24 October 1769 he made a formal speech announcing: "Now is Bishops Stortford open to all the ports of the world." Among his other works were: advice on Ferriby Sluice on the River Ancholme (1766); reports on the Forth \& Clyde Canal, the North Level and Wisbech outfall on the Nene, the Coventry Canal, and estimates for the Leeds and Selby Canal (1768–71); estimates for the extension of the Medway Navigation from Tonbridge to Edenbridge (1771); and between 1767 and 1777 he was consulted, with other engineers, by the City of London on problems regarding the Thames.

He joined the Northampton Philosophical Society shortly after its formation in 1743 and was President several times before he moved to London. In 1760 he became a member of the Society for the Encouragement of Arts, Manufactures and Commerce, and in 1763 he was chosen as joint Chairman of the Committee on Mechanics—a position he held until 1778. He was elected a Fellow of the Royal Society on 12 January 1764. On the formation of the Smeatonian Society of Civil Engineers, the forerunner of the present Institution of Civil Engineers, he was elected first President in 1771, remaining as such until his illness in 1780.
