Selman Waksman

Born 22 Jul 1888; died 16 Aug 1973 at age 85.Selman Abraham Waksman was an Ukrainian-American microbiologist and biochemist who was one of the world’s foremost authorities on soil microbiology. After the discovery of penicillin, he played a major role in initiating a calculated, systematic search for antibiotics among microbes. In 1939, Dubos, a previous student, pointed out a bacteria-killing agent in a soil microorganism. He introduced the term antibiotic, “against life.” In 1943, he isolated streptomycin from a mold he had known and studied early in his life. His consequent discovery of this antibiotic streptomycin, the first specific antibiotic effective against tuberculosis, earned him the 1952 Nobel Prize.
