Clinton Joseph Davisson (1881-1958). American physicist. He and G. P. Thomson shared the Nobel Prize in Physics in 1937 for demonstrating wave properties of electrons. 

Diffraction is a characteristic wave property. It is useful to recall that the mass of the electron was determined accurately by Millikan in 1909. A precise mass is very much a particle-type property. Geiger counters monitor P-particles (electrons) one by one ( click-click-click ) another particle property. The de Broglie equation suggests that wavelengths (X) are associated with electrons and that these should be on the order of 10"" m. In principle, electrons should be diffracted by crystals, a prediction confirmed in 1927 by Clinton Joseph Davisson (1881-1958) and Lester Halbert Germer (1896-1971), at Bell Telephone Laboratories. De Broglie was awarded the 1929 Nobel Prize in physics and Davisson won a share of the 1937 Nobel Prize in physics. 

Clinton Joseph Davisson (1881 1958) was an American physicist at Bell Telephone Laboratories. He discovered the diffraction of electrons with L.H. Germer, and together they received the Nobel Prize in 1937 for their experimental discovery of the diffraction cf electrons by crystals. The prize was shared with G.P. Thomson, who used a different diffraction method. George Paget Thomson (1892 -1975), son of the discoverer of the electron, Joseph John Thomson, and professor at Aberdeen, London, and Cambridge Universities.
