4 MacArthur, John Stewart
[br]b. December 1856 Hutchesontown, Glasgow, Scotlandd. 16 March 1920 Pollokshields, Glasgow, Scotland[br]Scottish industrial chemist who introduced the "cyanide process" for the commercial extraction of gold from its ores.[br]MacArthur served his apprenticeship in the laboratory of Tennant's Tharsis Sulphur and Copper Company in Glasgow. In 1886 he was appointed Technical Manager of the Tennant-run Cassel Gold Extracting Company. By 1888 he was advocating a treatment scheme in which gold was dissolved from crushed rock by a dilute solution of alkali cyanide and then precipitated onto finely divided zinc. During the next few years, with several assistants, he was extremely active in promoting the new gold-extraction technique in various parts of the world. In 1894 significant sums in royalty payments were received, but by 1897 the patents had been successfully contested; henceforth the Cassel Company concentrated on the production and marketing of the essential sodium cyanide reagent.MacArthur was Managing Director of the Cassel Company from 1892 to 1897; he resigned as a director in December 1905. In 1907 he created the Antimony Recovery Syndicate, and in 1911 he set up a small plant at Runcorn, Cheshire, to produce radium salts. In 1915 this radium-extraction activity was transferred to Balloch, south of Loch Lomond, where it was used until some years after his death.[br]Principal Honours and DistinctionsInstitution of Mining and Metallurgy Gold Medal 1902.Bibliography10 August 1888, jointly with R.W.Forrest and W.Forrest, British patent no. 14,174. 13 July 1889, jointly with R.W.Forrest and W.

5 Drinker, Cecil Kent
SUBJECT AREA: Medical technology[br]b. 17 March 1887 Philadelphia, Pennsylvania, USAd. 14 April 1956 Falmouth, Massachusetts, USA[br]American physiologist, co-inventor of the Drinker respirator (iron lung).[br]Drinker attended the University of Pennsylvania and graduated MD in 1913. After clinical experience in Boston and, in 1915–16, at Johns Hopkins, he joined the Department of Physiology at Harvard and was appointed Professor in 1924. Apart from continuing his activities in applied physiology, he was also head of the Department of Public Health. As well as investigating poisoning from radium, manganese and carbon monoxide, he was also engaged in a study of the lymphatics and respiration. During the Second World War his earlier work on the iron lung, which he had developed in 1927 with his brother Philip (1894–1972), was deployed in the study and improvement of high-altitude oxygen masks and decompression equipment for service use. He continued an association with the Naval Medical College until 1954, but retired from Harvard in 1948.[br]Bibliography1929, "The use of a new apparatus for the prolonged administration of artificial respiration", American Medical Association (with P.
