Davisson, Clinton Joseph

Davisson, Clinton Joseph, 1881-1958, American physicist, b. Bloomington, Ill. He joined the engineering department of the Bell Telephone Laboratories in 1917. Davisson worked on thermionics, magnetism, and electron diffraction. His demonstrations with L. H. Germer in 1927 confirmed Louis de Broglie's theory of the wave nature of moving electrons by means of diffraction by crystals. For this he shared with G. P. Thomson the 1937 Nobel Prize in Physics.
Davisson is a lunar impact crater that is located on the far side of the Moon from the Earth. This crater lies across the eastern rim of the huge Leibnitz walled plain, and the rim and outer rampart intrudes into the interior floor of Leibnitz. To the east-northeast of Davisson in the Oppenheimer walled plain, a formation only somewhat smaller than Leibnitz.

The rim of Davisson has been somewhat eroded from impacts, but it retains some detail from its original formation. Particularly along the western face, the interior wall displays some terraces. The rim is more worn along the northeastern face, and the rim is more irregular to the north and south. The interior floor is relatively level and feaureless, with a low central peak offset slightly to the southwest of the crater mid-point.

This crater is named after Clinton Joseph Davisson (1881–1958) a US physicist who in 1927 made the first experimental observation of the wave nature of electrons, for which he was awarded the Nobel Prize for Physics in 1937. Davisson was born in Bloomington, Illinois, and studied at the University of Chicago and Princeton University. He worked for the Western Electric Company (later Bell Telephone Laboratories) in New York 1917–46. With Lester Germer (1896–1971), Davisson discovered that electrons can undergo diffraction, in accordance with French physicist Louis de Broglie's theory that electrons and all other elementary particles can show wavelike behaviour.
