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.
