Career

Joshua Lederberg, the son of a Jewish rabbi, attended high school in New York, studied zoology at Columbia University from 1941 to 1944, and received his doctorate ( Ph.D. ) from Yale University in 1947 with Edward Tatum .

He married the molecular biologist and geneticist Esther Lederberg and together with her developed the stamping technique for transferring a bacterial colony from one Petri dish to another.

From 1947 to 1959 he was a professor at the University of Wisconsin – Madison , then at Stanford University in Palo Alto ( California ). In 1978 he returned to New York and became 5th President of Rockefeller University .

After his retirement in 1990 he returned to his laboratory and continued to devote himself to his own research projects and the training of students.

Research topics

In 1952, based on the research carried out by his wife Esther Lederberg , Lederberg and his student Norton Zinder were able to demonstrate that bacteriophages can transfer parts of a bacterial genome to another bacterium ( transduction ).

In the same year he introduced the term plasmid for the circular DNA present next to the main chromosomes . He also developed a process for replica plating .
