Raymond (Ray) Davis, Jr. (October 14, 1914 – May 31, 2006) was an American chemist, physicist, and Nobel Prize in Physics laureate.
Davis was born in Washington, D.C., where his father was a photographer for the National Bureau of Standards. He spent several years as a choirboy to please his mother, although he could not carry a tune. He enjoyed attending the concerts at the Watergate before air traffic was loud enough to drown out the music. His brother Warren, 14 months younger than he, was his constant companion in boyhood. He graduated in chemistry from the University of Maryland in 1938. He also received a master's degree from that school and a Ph.D. from Yale University in physical chemistry in 1942.
Davis spent most of the war years at Dugway Proving Ground, Utah observing the results of chemical weapons tests and exploring the Great Salt Lake basin for evidence of its predecessor, Lake Bonneville.
