Walter Dunhan Claus

Walter Dunham Claus (6 March 1903 – 12 May 1995) was an American biophysicist who worked in radiation biology and medical physics.

Early life and education

He was born in St. Louis, Missouri and died in Golden, Jefferson County, Colorado. Claus's father Ernest Claus was from Germany and his mother Laura Claus was from Missouri. They resided at 310 N. Stein in St. Louis, Missouri. In 1931 received his Ph.D. in physics from Washington University in St. Louis, for a doctoral thesis titled Effect of Temperature on the Diffuse Scattering of X-rays from Rock Salt. From 1931 through 1933, Claus continued to study X-ray effects as a National Research Council fellow. He then worked at the Mellon Institute and eventually joined the Atomic Energy Commission.

Career

Atomic Energy Commission

In 1954, Claus oversaw the testing of samples from the Marshall Islands for radioactive fallout from the Castle Bravo explosion. From 1949-1955 he held the position of Chief in the Division of Biology and Medicine, AEC. Then from 1955-1967 he served as Special Assistant to Division Director, AEC.

Health Physics Society

Claus was a key member in the formation of the Health Physics Society and represented the U.S. Atomic Energy Commission. In 1955, he was one of the founding members and part of the initial board of directors. He would also serve as the society's president during 1961 and 1962.
