William Carmichael M'Intosh, F.R.S., (10 Oct. - St. Andrews, Fife) 1838-1931 (1 Apr.), educated at the university of St. Andrews (where i.a. J. Goodsir (q.v.) was one of his professors (the one he was most impressed by)), returned there as professor 1882 after 20 years as director of a mental asylum (where he had been aquainted with the chief physician in the county, Dr. Fraser Thompson, 1806-1871 (Oct.), who was an amateur naturalist as well) [Lagisca fraserthomsoni (M'Intosh, 1897)]. M'Intosh had applied for the professorship in Edinburgh 12 years before he was appointed professor at St. Andrews, but was then defeated by the older Wyville Thomson (q.v.). M'Intosh is well-known as author of "A Monograph of the British Marine Annelids". Medical experience made him a Total Abstinence man and he only used alcohol for preservation of worms [Aphelochaeta mcintoshi (Southern, 1914), Leptomesochra macintoshi (T. & A. Scott, 1895), Malmgrenia mcintoshi (Tebble & Chambers, 1982), Intoshella Darboux, 1899, Ototyphlonemertes (Otohelicophora) macintoshi Bürger, 1895, Rhopalura intoshi Metschnikoff, 1881, Intoshia Giard, 1877, Epizoanthus macintoshi Haddon & Shackleton, 1891, Hyalopomatus macintoshi (Gravier, 1911), Lineus mcintoshi (Langerhans, 1880), Glycera macintoshi Grube, 1877, Lysilla macintoshi Gravier, 1907, Sabellaria intoshi Fauvel, 1914, Marphysa macintoshi Crossland, Terebellides intoshi Caullery, 1915, Eupolymnia intoshi (Caullery, 1944), Thelepus mcintoshi Grube, 1878]. He was succeded 1917 by Sir D'Arcy Wentworth Thompson William's younger sister Roberta Mitchell M'Intosh Gunther, 1843-1869 [Tetrastemma robertianae, Eteone robertianae (M'Intosh, 1874)], died, when giving birth to her son Robert William Theodore. She was a skilful illustrator. Most of the coloured plates in her brothers monograph were painted by her. The family name is sometimes spelled McIntosh. - Edit

William Carmichael M'Intosh FRSE FRS FLS (also spelt McIntosh; 10 October 1838, St Andrews - 1 April 1931, St Andrews) was a Scottish physician and marine zoologist. He served as president of the Ray Society, as vice-president of the Royal Society of Edinburgh (1927-30), and was awarded the Neill Prize (1865-8). His medical qualification (LRCSE) was granted in 1860 by the Royal College of Surgeons of Edinburgh, following study at Edinburgh University. McIntosh worked initially as an asylum doctor and was Director of the Perthshire District Asylum at Murthly for eighteen years. He later became a renowned botanist and marine biologist, travelling on HMS Challenger during the Challenger expedition of 1872 to 1876. He was Professor of Natural History at St Andrews University from 1882 to 1917, succeeded by D'Arcy Wentworth Thompson. He was also Director of the University Museum and was the first director of the University's Gatty Marine Laboratory (founded 1896). McIntosh was also a Fellow of the Linnean Society of London, a Fellow of the Royal Society of Edinburgh, and a Corresponding Member of the Zoological Society. He was elected a Fellow of the Royal Society in 1877, and was awarded the Royal Society's Royal Medal in 1899: "For his important monographs on British marine zoology and on the fishing industries." He received the honorary degree Doctor of laws (LL.D.) from the University of St Andrews in 1900, and was awarded the Linnean Medal in 1924. He published two major works in his life, A Monograph of the British Annelids (1838-1931) in four parts and nine volumes and The Marine Invertebrates and Fishes of St. Andrews (1875) ... Reports on important collections made during various cruises under Government and other auspices have largely occupied the attention of Professor McIntosh. Annelids from Canada, Kerguelen's Island (Transit of Venus Expedition), from the Polar Sea (British North Polar Expedition), and extensive collections made by the " Valorous " and the " Porcupine " have passed under his skilled examination; but his greatest achievement of this kind is the ponderous volume dealing with the collection brought home by H.M.S. Challenger,—a volume which the late Dr. W. B. Carpenter prophesied would "mark an era in our knowledge of this important division of the Marine Invertebrata." Extending to almost six hundred pages, and embracing nearly a hundred exquisite plates, it forms one the most valuable of the great " Challenger " series, and occupied nearly seven years in its preparation - Edit
