From 1942 to 1955, Dr. Leake was executive vice president in charge of the medical bureau at the University of Texas at Galveston. From there he moved to Ohio State University, where he was professor of pharmacology and then coordinator of student research learning for 10 years.
In 1965, he returned to the University of California at San Francisco as senior lecturer on pharmacology and the history and philosophy of medicine.
Over the years, Dr. Leake had lectured widely at colleges, universities and other institutions throughout the country. A prolific writer, he was the author of hundreds of medical and scientific articles and books.
He had been a consultant to the American Red Cross, the U.S. Public Health Service and the Army Medical Library. Dr. Leake belonged to numerous medical and scientific organizations. He was a member of the Cosmos Club here.
