Weigle, Jean Jacques (Physicist, Biologist)



  • Existence: 1901 - 1968


Background: Caltech Research Associate in Biology, 1949-1968.


Description: Jean Weigle's scientific career consisted of two distinct and distinguished halves, the first as a physicist and the second as a biologist. A professor and head of the physics department at the University of Geneva from 1931 to 1948, Weigle resigned his position in Geneva after suffering a heart attack and became a research associate in Biology at Caltech. His work as a biologist focused on the interaction between viruses and hosts, including work on the lambda virus. He is most noted for his demonstration with Matt Meselson of Caltech and Grete Kellenberger of Geneva that genetic recombination involves actual breakage and reunion of DNA molecules.
