Lederberg, Joshua He was born in Montclair, N.J. on May 23,1925. He was brought up in the Washington Heights District of Upper Manhattan, New York City, where he received his education in Public School 46, Junior High School 164 and Stuyvesant High School. From 1941 to 1944 he studied at Columbia College, where he obtained his B.A. with honours in Zoology (premedical course), and from 1944 to 1946 at the College of Physicians and Surgeons of Columbia University Medical School. Here he carried out part-time research with Professor F. J. Ryan in the Department of Zoology. Subsequently he went to the Department of Microbiology and Botany at Yale University, New Haven, Conn., as Research Fellow of the Jane Coffin Childs Fund for Medical Research and, during 1946-1947, as a graduate student with Professor E. L. Tatum. He was awarded his Ph.D. degree in 1948. In 1947, he was appointed Assistant Professor of Genetics at the University of Wisconsin, where he was promoted to Associate Professor in 1950 and Professor in 1954. He organized the Department of Medical Genetics in 1957, of which he was Chairman during 1957-1958.

CONTACT entire Web this site American geneticist at Stanford University who shared the 1958 Nobel Prize in Physiology or Medicine with George Beadle and Edward Tatum for discovering the mechanisms of genetic recombination in bacteria . With Tatum, Lederberg showed that the offspring of different mutants of Escherichia coli had genese recombined from those of the original generation, thus establishing the sexuality of E. coli . Later he showed that genetic information could be carried between Salmonella by certain bacterial viruses. In 1958, while at the University of Wisconsin (where he was chairman of the medical genetics department), Lederberg was the first to raise the issue of biological contamination by space missions. He was subsequently appointed chairman of WESTEX and then of the Space Science Board 's Committee 14 on Exobiology . In 1960, Lederberg introduced the term " exobiology and in 1961 was among the group of researchers who attended the first SETI conference at Green Bank References Lederberg, J., and Cowie, D. B.
