101 Garforth, William Edward
SUBJECT AREA: Mining and extraction technology[br]b. 1845 Dukinfield, Cheshire, Englandd. 1 October 1921 Pontefract, Yorkshire, England[br]English colliery manager, pioneer in machine-holing and the safety of mines.[br]After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.[br]Principal Honours and DistinctionsKnighted 1914.

102 Pounder, Cuthbert Coulson
[br]b. 10 May 1891 Hartlepool, Englandd. 18 December 1982 Belfast (?), Northern Ireland[br]English marine engineer and exponent of the slow-speed diesel engine.[br]Pounder served an apprenticeship with Richardsons Westgarth, marine engineers in north east England. Shortly after, he moved to Harland \& Wolff of Belfast and there fulfilled his life's work. He rose to the rank of Director but is remembered for his outstanding leadership in producing the most advanced steam and diesel machinery installations of their time. Harland \& Wolff were the main licensees for the Burmeister \& Wain marine diesel system, and the Copenhagen company made most of the decisions on design; however, Pounder often found himself in the hot seat and once had the responsibility of concurring with the shipyard's decision to build three Atlantic liners with the largest diesel engines in the world, well beyond the accepted safe levels of extrapolation. With this, Belfast secured worldwide recognition as builders of diesel-driven liners. During the German occupation of Denmark (1940–5), the engineering department at Belfast worked on its own and through systematic research and experimentation built up a database of information that was invaluable in the postwar years.Pounder was instrumental in the development of airless injection diesel fuel pumps. He was a stalwart supporter of all research and development, and while at Belfast was involved in the building of twelve hundred power units. While in his twenties, Pounder began a literary career which continued for sixty years. The bulk of his books and papers were on engineering and arguably the best known is his work on marine diesel engines, which ran to many editions. He was Chairman of Pametrada, the marine engineering research council of Great Britain, and later of the machinery committee of the British Ship Research Association. He regarded good relations within the industry as a matter of paramount importance.[br]Principal Honours and DistinctionsPresident, Institute of Marine Engineers; Denny Gold Medal 1839, 1959.
