Robert Woodrow Wilson

Robert Woodrow Wilson

American radio astronomer who shared, with Arno Penzias, the 1978 Nobel Prize for Physics for a discovery that supported the big-bang model of creation. (Soviet physicist Pyotr Leonidovich Kapitsa also shared the award, for unrelated research.)
Educated at Rice University, Houston, and the California Institute of Technology, Pasadena, where he received his doctorate in 1962, Wilson then worked (1963-76) at the Bell Telephone Laboratories at Holmdel, N.J., where, in collaboration with Penzias, he began monitoring radio emissions from a ring of gas encircling the Milky Way Galaxy. The two scientists detected an unusual background radiation that seemed to permeate the cosmos uniformly and indicated a temperature of 3 K. This radiation appeared to be a remnant of the big bang, the primordial explosion billions of years ago from which the universe originated.

From 1976 Wilson was head of Bell's Radio Physics Research Department. He contributed to many scientific journals on such subjects as background-temperature measurements and millimetre-wave measurements of interstellar molecules. He became a member of the U.S. National Academy of Science in 1979.
