John Alexander Simpson (November 3, 1916 – August 31, 2000) worked as an experimental nuclear, and cosmic ray physicist who was deeply committed to educating the public and political leaders about science and its implications.〔''Eugene N. Parker'', National Academies Press. ("John Alexander Simpson BIOGRAPHICAL MEMOIRS" ). Visited on August the 28th, 2010.〕 The year he died, his instruments in space had been sending data back for nearly 40 years.〔National, The New York Times. ("John Alexander Simpson, 83, Nuclear and Cosmic Scientist" ), September 7, 2000. Visited on September 1st, 2010.〕 Simpson spent his career as an instructor and researcher for the University of Chicago Physics department. His research continued up until a few weeks prior to his death on August 31 of 2000.〔〔〔 He is known for inventions such as ''the gas flow a-particle proportional counter for measuring plutonium yields in the presence of high intensity fission products'', and the ''neutron monitor''.〔 And also for having several of the instruments he created launched into space.〔''Pearce Wright'', The Guardian. ("John Simpson" ), Thursday 14 September 2000. Visited on August the 28th, 2010.〕 John A. Simpson died at age 83. His death was caused from a case of Pneumonia in which he contracted in the hospital following a successful heart surgery, and he is survived by his wife Elizabeth, and by his two children Mary Ann and Simpson from his first marriage.〔〔 ==Early life==
Born in Portland, Oregon, Simpson was an accomplished clarinetist and saxophonist in his early years, receiving recognition in high school with an award for his virtuosity.〔 He received an AB degree from Reed College in 1940, where he became interested in the history of science and technology spanning from the Greeks and Romans to the Middle Ages, to the most recent discoveries in astronomy and physics.〔〔''Moore, Mike'', Bulletin of the Atomic Scientists.("Remembering John Simpson.(nuclear physicist)(Obituary)" ), November 1, 2000. Visited on September 1st, 2010.〕〔Simpson, J. A. (1940). An experimental electron microscope (Doctoral dissertation, Reed College).〕 He obtained an MS from New York University in 1943, and a Ph.D a year later.〔''Welther, B. L.'', Bulletin of the American Astronomical Society. ("Obituary: John Alexander Simpson, 1916-2000 (Bulletin of the American Astronomical Society ; vol. 33, no. 4, p. 1581-1582) ). Visited on August the 28th, 2010.〕〔''Forum on Physics & Society'' American Physical Society. ("1999 Leo Szilard Lectureship Award Recipient" ). Visited on August the 28th, 2010.〕 It was at New York University in 1943 when Simpson first got his invitation to become employed at Chicago University. Volney Wilson, an administrator at the Metallurgical Laboratory of the university had asked him to come help invent instruments for measuring high levels of radioactivity. It took much convincing, but Simpson finally agreed to help.〔
