Raymond Davis Jr.

Raymond Davis Jr. (October 14, 1914 – May 31, 2006) was an American chemist and physicist. He is best known as the leader of the Homestake experiment in the 1960s-1980s, which was the first experiment to detect neutrinos emitted from the Sun; for this he shared the 2002 Nobel Prize in Physics.

Early life and education 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 received his B.S. from the University of Maryland in 1938 in chemistry, which is part of the University of Maryland College of Computer, Mathematical, and Natural Sciences. He also received a master's degree from that school and a Ph.D. from Yale University in physical chemistry in 1942.

Career After entering the Army as a reserve officer in 1942, Davis spent most of World War II at Dugway Proving Ground, Utah

After his discharge from the Army in 1945,

Davis shared the Nobel Prize in Physics in 2002 with Japanese physicist Masatoshi Koshiba and Italian Riccardo Giacconi for pioneering contributions to astrophysics, Davis was recognized for his work on the detection of cosmic neutrinos,
