Gunther Stent Stent joined the small group of phage workers under Max Delbrück at the California Institute of Technology in Pasadena, California. This phage group was the incubator for many of the fundamental ideas of the newly emerging science of molecular biology.

Later, in his memoirs, Stent described some of his activities and interactions with others of the group.
