Charles Rawlinson Park
Charles Rawlinson Park, better known as Rollo by his many friends and associates, was born in Baltimore, Maryland on March 2, 1916. His father, Edwards A. Park, was on the staff of Johns Hopkins Medical School and later became Chairman of the Department of Pediatrics there. His mother introduced and supervised nursery schools in Baltimore and subsequently throughout Baltimore and Delaware. Rollo graduated A.B. from Harvard College in 1937 and M.D. in 1941 from Johns Hopkins, where he was elected to Alpha Omega Alpha and Phi Beta Kappa. He interned at Johns Hopkins Hospital and then was appointed Resident and Chief Resident in - Medicine at Peter Bent Brigham Hospital in Boston. During his student days at Johns Hopkins, he made an auspicious entry in the world of investigative medicine by reporting, in collaboration with W. Barry Wood, Jr., that p-aminobenzoic acid was an essential factor for bacterial growth.
He entered the U.S. Army Medical Corps in 1944 and was stationed at Fort Knox, Kentucky until 1947. During this period, he carried out studies of thermal regulation during fever and heat acclimatization in man. Upon his release from the Army, Rollo worked as a Postdoctoral Welch Fellow and later as an Assistant Professor of, Medicine in the laboratory of Carl and Gerty Cori in the Department of Biochemistry, Washington University in St. Louis. This laboratory was a "Mecca" for biochemical investigators, and during this period Rollo rubbed shoulders with many young scientists who like him, would make their mark in the world of biochemical research. Four of these, Earl Sutherland, Sidney Colowick, Victor Najjar and Janey Park subsequently became faculty members at Vanderbilt. Rollo's work in collaboration with other members of the Cori laboratory resulted in the findings that growth hormone and diabetic serum exerted anti-insulin effects on glucose uptake in muscle.
