Harvey S. Gellman
Harvey S. Gellman (1924–2003) was born in Poland and emigrated to Canada when he was very young. After getting a Ph.D., he launched a successful career as a consultant in Toronto. He was remembered as being "one of Canada's computer pioneers and most distinguished consultants".〔(【引用サイトリンク】title=Remembering Harvey )〕
==Studies==
H. S. Gellman got his doctorate in Applied Mathematics at the University of Toronto in 1951. While working on his thesis, he worked at the first computer center in Canada at the University of Toronto, a Ferranti (one of 9 made according to the Computer History Museum), and did the programming. His Ph. D. work was on the origins of the Earth's magnetic field and his thesis was "Computation of the magnetic field produced by a moving liquid",〔http://www.ams.org/bull/1952-58-03/S0002-9904-1952-09602-6/S0002-9904-1952-09602-6.pdf〕 with his supervisor Edward Bullard.〔This work is summarized in ''Encyclopedia of Geomagnetism and Paleomagnetism'', by David Gubbins, Emilio Herrero-Bervera, 2007:166.〕 The Bullard-Gellman Dynamo, presented in a pioneering paper in 1954, was the first convincing qualitative model for dynamo action in a fluid sphere.〔(【引用サイトリンク】title=Encyclopedia of Geomagnetism and Paleomagnetism )〕
Harvey reported to his coauthor, Alistair Davidson, that the Ferranti computer cost approximately $300,000. At that time, he was earning $3,000 as a graduate student.
