From 1844 until 1962, the Clyde shipyard of William Denny and Brothers, Dumbarton, produced over 1,500 ships, trained innumerable students of all nationalities in shipbuilding and marine engineering, and for the seventy-plus years of their existence were accepted worldwide as the leaders in the application of science to ship design and construction. Until the closure of the yard members of the Denny family were among the partners and later directors of the firm: they included men as distinguished as Dr Peter Denny (1821(?)–95), Sir Archibald Denny (1860–1936) and Sir Maurice Denny (1886– 1955), the main collaborator in the design of the Denny-Brown ship stabilizer.

One of the most influential of this shipbuilding family was William Denny, now referred to as William 3! His early education was at Dumbarton, then on Jersey and finally at the Royal High School, Edinburgh, before he commenced an apprenticeship at his father's shipyard. From the outset he not only showed great aptitude for learning and hard work but also displayed an ability to create good relationships with all he came into contact with. At the early age of 21 he was admitted a partner of the shipbuilding business of William Denny and Brothers, and some years later also of the associated engineering firm of Denny \& Co. His deep-felt interest in what is now known as industrial relations led him in 1871 to set up a piecework system of payment in the shipyard. In this he was helped by the Yard Manager, Richard Ramage, who later was to found the Leith shipyard, which produced the world's most elegant steam yachts. This research was published later as a pamphlet called The Worth of Wages, an unusual and forward-looking action for the 1860s, when Denny maintained that an absentee employer should earn as much contempt and disapproval as an absentee landlord! In 1880 he initiated an awards scheme for all company employees, with grants and awards for inventions and production improvements. William Denny was not slow to impose new methods and to research naval architecture, a special interest being progressive ship trials with a view to predicting effective horsepower. In time this led to his proposal to the partners to build a ship model testing tank beside the Dumbarton shipyard; this scheme was completed in 1883 and was to the third in the world (after the Admiralty tank at Torquay, managed by William Froude and the Royal Netherlands Navy facility at Amsterdam, under B.J. Tideman. In 1876 the Denny Shipyard started work with mild-quality shipbuilding steel on hulls for the Irrawaddy Flotilla Company, and in 1879 the world's first two ships of any size using this weight-saving material were produced: they were the Rotomahana for the Union Steamship Company of New Zealand and the Buenos Ayrean for the Allan Line of Glasgow. On the naval-architecture side he was involved in Denny's proposals for standard cross curves of stability for all ships, which had far-reaching effects and are now accepted worldwide. He served on the committee working on improvements to the Load Line regulations and many other similar public bodies. After a severe bout of typhoid and an almost unacceptable burden of work, he left the United Kingdom for South America in June 1886 to attend to business with La Platense Flotilla Company, an associate company of William Denny and Brothers. In March the following year, while in Buenos Aires, he died by his own hand, a death that caused great and genuine sadness in the West of Scotland and elsewhere.

Of Scandinavian parentage, Arup attended school in Germany and Denmark before taking his degree in mathematics and philosophy at Copenhagen University in 1914. He then graduated as a civil engineer from the Royal Technical College in the same city, specializing in the theory of structures.

Arup retained close ties with Europe for some time, working in Hamburg as a designer for the Danish civil engineering firm of Christiani \& Nielsen. Then, in the 1930s, he began what was to be a long career in England as an engineering consultant to a number of architects who were beginning to build with modern materials (par-ticularly concrete) and methods of construction. He became consultant to the famous firm of Tecton (under the direction of Berthold Lubetkin) and was closely associated with the leading projects of that firm at the time, notably the High-point flats at Highgate, the Finsbury Health Centre and the award-winning Penguin Pool at the Regent's Park Zoological Gardens, all in London.

In 1945 Arup founded his own firm, Ove Arup \& Partners, working entirely as a consultant to architects, particularly on structural schemes, and in 1963 he set up a partnership of architects and engineers, Arup Associates. The many and varied projects with which he was concerned included Coventry Cathedral and the University of Sussex with Sir Basil Spence, the Sydney Opera House with Joern Utzon and St Catherine's College, Oxford, with Arne Jacobsen.

Richard Edmund Reason was educated at Tonbridge School and the Royal College of Science (Imperial College), where he studied under Professor A.F.C.Pollard, Professor of Technical Optics. After graduating in 1925 he joined Taylor, Taylor and Hobson Ltd, Leicester, manufacturers of optical, electrical and scientific instruments, and remained with that firm throughout his career. One of his first contributions was in the development, with E.F.Fincham, of the Fincham Coincidence Optometer. At this time the firm, under William Taylor, was mainly concerned with optical instruments and lens manufacture, but in the 1930s Reason was also engaged in developing means for measuring the roughness of machined surfaces. The need for establishing standards and methods of measurement of surface finish was called for when the subcontracting of aero-engine components became necessary during the Second World War. This led to the development by Reason of an instrument in which a stylus was moved across the surface and the profile recorded electronically. This was called the Talysurf and was first produced in 1941. Further development followed, and from 1947 Reason tackled the problem of measuring roundness, producing the first Talyrond machine in 1949. The technology developed for these instruments was used in the production of others such as the Talymin Comparator and the Talyvel electronic level. Reason was also associated with the development of optical projection systems to measure the profile of parts such as gear teeth, screw threads and turbine blades. He retired in 1968 but continued as a consultant to the company. He served for many years on committees of the British Standards Institution on surface metrology and was a representative of Britain at the International Standards Organization.

Edward Geisler Herbert was educated at Nottingham High School in 1876–87, and at University College, London, in 1887–90, graduating with a BSc in Physics in 1889 and remaining for a further year to take an engineering course. He began his career as a premium apprentice at the Nottingham works of Messrs James Hill \& Co, manufacturers of lace machinery. In 1892 he became a partner with Charles Richardson in the firm of Richardson \& Herbert, electrical engineers in Manchester, and when this partnership was dissolved in 1895 he carried on the business in his own name and began to produce machine tools. He remained as Managing Director of this firm, reconstituted in 1902 as a limited liability company styled Edward G.Herbert Ltd, until his retirement in 1928. He was joined by Charles Fletcher (1868–1930), who as joint Managing Director contributed greatly to the commercial success of the firm, which specialized in the manufacture of small machine tools and testing machinery.

Around 1900 Herbert had discovered that hacksaw machines cut very much quicker when only a few teeth are in operation, and in 1902 he patented a machine which utilized this concept by automatically changing the angle of incidence of the blade as cutting proceeded. These saws were commercially successful, but by 1912, when his original patents were approaching expiry, Herbert and Fletcher began to develop improved methods of applying the rapid-saw concept. From this work the well-known Rapidor and Manchester saws emerged soon after the First World War. A file-testing machine invented by Herbert before the war made an autographic record of the life and performance of the file and brought him into close contact with the file and tool steel manufacturers of Sheffield. A tool-steel testing machine, working like a lathe, was introduced when high-speed steel had just come into general use, and Herbert became a prominent member of the Cutting Tools Research Committee of the Institution of Mechanical Engineers in 1919, carrying out many investigations for that body and compiling four of its Reports published between 1927 and 1933. He was the first to conceive the idea of the "tool-work" thermocouple which allowed cutting tool temperatures to be accurately measured. For this advance he was awarded the Thomas Hawksley Gold Medal of the Institution in 1926.

His best-known invention was the Pendulum Hardness Tester, introduced in 1923. This used a spherical indentor, which was rolled over, rather than being pushed into, the surface being examined, by a small, heavy, inverted pendulum. The period of oscillation of this pendulum provided a sensitive measurement of the specimen's hardness. Following this work Herbert introduced his "Cloudburst" surface hardening process, in which hardened steel engineering components were bombarded by steel balls moving at random in all directions at very high velocities like gaseous molecules. This treatment superhardened the surface of the components, improved their resistance to abrasion, and revealed any surface defects. After bombardment the hardness of the superficially hardened layers increased slowly and spontaneously by a room-temperature ageing process. After his retirement in 1928 Herbert devoted himself to a detailed study of the influence of intense magnetic fields on the hardening of steels.

Herbert was a member of several learned societies, including the Manchester Association of Engineers, the Institute of Metals, the American Society of Mechanical Engineers and the Institution of Mechanical Engineers. He retained a seat on the Board of his company from his retirement until the end of his life.

William Taylor served an apprenticeship from 1880 to 1885 in London with Paterson and Cooper, electrical engineers and instrument makers. He studied at the Finsbury Technical College under Professors W.E.Ayrton (1847–1908) and John Perry (1850–1920). He remained with Paterson and Cooper until 1887, when he joined his elder brother, who had set up in Leicester as a manufacturer of optical instruments. The firm was then styled T.S. \& W.Taylor and a few months later, when H.W.Hobson joined them as a partner, it became Taylor, Taylor and Hobson, as it was known for many years.

William Taylor was mainly responsible for technical developments in the firm and he designed the special machine tools required for making lenses and their mountings. However, his most notable work was in originating methods of measuring and gauging screw threads. He proposed a standard screw-thread for lens mountings that was adopted by the Royal Photographic Society, and he served on screw thread committees of the British Standards Institution and the British Association. His interest in golf led him to study the flight of the golf ball, and he designed and patented the "Dimple" golf ball and a mechanical driving machine for testing golf balls.

He was an active member of the Institution of Mechanical Engineers, being elected Associate Member in 1894, Member in 1901 and Honorary Life Member in 1936. He served on the Council from 1918 and was President in 1932. He took a keen interest in engineering education and advocated the scientific study of materials, processes and machine tools, and of management. His death occurred suddenly while he was helping to rescue his son's car from a snowdrift.

The son of a lawyer, he entered an academy in Cape Cod and, at the age of 19, the English Academy at Andover, Massachusetts, for five terms. He was then in the employ of Samuel L. Fenton of Charlestown, Massachusetts. He served a three-year apprenticeship, then went to the Windsor White River Division of the Vermont Central Railroad. He was Resident Engineer of the Cheshire Railroad at Walpote, New Hampshire, from 1847 to 1849, and then worked in independent practice as a civil engineer and surveyor until his death. He was involved with nearly all the railroads running out of Boston, especially the Boston \& Maine. In April 1863 he was appointed Chief Engineer of the Hoosac Tunnel, which was already being built. He introduced new engineering methods, relocated the line of the tunnel and achieved great accuracy in the meeting of the borings. He was largely responsible for the development in the USA of the advanced system of tunnelling with machinery and explosives, and pioneered the use of compressed air in the USA. In 1869 he was Chief Engineer of the Burlington \& Missouri River Railroad in Nebraska, laying down some 240 miles (386 km) of track in four years. During this period he became interested in the building of a Congregational College at Crete, Nebraska, for which he gave the land and which was named after him. In 1873 he returned to Charlestown and was again appointed Chief Engineer of the Hoosac Tunnel. At the final opening of the tunnel on 9 February 1875 he drove the first engine through. He remained in charge of construction for a further two years.
