1909–75, American geneticist, b. Boulder, Colo., grad. Univ. of Wisconsin (B.A., 1931; M.S., 1932; Ph.D., 1935). From 1937 to 1945 he taught at Stanford and from 1945 to 1948 at Yale.

Lederberg showed that although bacteria reproduce only by dividing, they are able to effect sexual recombination by processes that result in exchange of genetic material between different bacteria. A pioneer in the fields of bacterial genetics, microbiology, and molecular biology, he taught at the Univ. of Wisconsin (1947–59) and Stanford Univ. (1959–78) and joined Rockefeller Univ. in 1978 as its president, serving until 1990.
Born May 23, 1925, in Montclair, N.J., USA. American geneticist and biochemist.
Lederberg graduated from Columbia University in 1944 and continued his education at Yale University, where he received the doctor of philosophy degree in 1947. From 1947 to 1958 he was at the University of Wisconsin. Since 1959 he has been a professor at the Medical School of Stanford University in Palo Alto and head of its Laboratory for Molecular Medicine and simultaneously (since 1962) professor at the University of California at Berkeley. He discovered the mechanism of genetic recombination in bacteria in 1947. Lederberg was awarded the Nobel Prize in 1958 together with G. Beadle and E. Tatum for research on the genetics of microorganisms.
