||1904: Cyril Stanley Smith born ... metallurgist who in 1943-44 determined the properties and technology of plutonium and uranium, the essential materials in the atomic bombs that were first exploded in 1945. Smith already then had 15 years of experience as a research metallurgist with the American Brass Co., during which time he studied properties of alloys and their microstructure. In WW II, he joined the Los Alamos Laboratory at its inception (1943). The properties and technology of plutonium had to be conducted with extremely limited quantities of available material. Smith and his group found it was unique, with five different allotropic forms with huge density differences between them. Postwar, he organized the Institute for the Study of Metal at the Univ. of Chicago. Pic.
