Heinz Fraenkel-Conrat is an internationally known German-born biochemist who became a naturalized citizen of the United States. The majority of his research, and the studies for which he is best known, was conducted at the University of Berkeley, California. Fraenkel-Conrat's research helped advance the study of viruses. He determined that under certain conditions, a virus could be separated into its component parts. These studies revealed both the virus's infective agent and its method of replication. Fraenkel-Conrat's research inspired numerous studies of viruses, which proved useful in the explanation of molecular biological processes such as replication and mutation.
