Frank Harold SpeddingBorn 22 Oct 1902; died 15 Dec 1984 at age 82.American chemist who, during the 1940s and '50s, developed processes for reducing individual rare-earth elements to the metallic state at low cost, thereby making these substances available to industry at reasonable prices. Earlier, upon the discovery of nuclear fission in 1939, the U.S. government asked leading scientists to join in the development of nuclear energy. In 1942, Iowa State College's Frank H. Spedding, an expert in the chemistry of rare earths, agreed to set up the Ames portion of the Manhattan Project, resulting in an easy and inexpensive procedure to produce high quality uranium. Between 1942 and 1945, almost two million pounds of uranium was processed on campus, in the old Popcorn Laboratory. |
