Roger Cloutier was born in North Attleborough, Massachusetts in 1930. After serving in the U.S. Navy during the Korean War, he pursued a career in health physics. In 1959, he moved to Oak Ridge to work for ORINS, the Oak Ridge Institute of Nuclear Studies (now Oak Ridge Associated Universities, or ORAU), and went on to serve as director of ORAU’s Professional Training Programs. In this interview, Cloutier recalls his career at ORAU and describes the medical innovations he was a part of, including advances in the use of radioisotopes to treat disease. He gives a history of other programs at ORAU, and explains how ORINS was started at the suggestion of Manhattan Project physicist Katharine Way.
Louis Hempelmann was J. Robert Oppenheimer’s physician and close friend.

Hempelmann remembers driving to Trinity Site with George Kistiakowsky and the high explosives—on Friday the 13th.
