The 1937 Nobel Prize in Physics recognized the experimental confirmation that electrons, traditionally viewed as particles, exhibit wave-like behavior through diffraction. Clinton Davisson, working alongside colleague Lester Germer at Bell Telephone Laboratories, utilized a nickel crystal to demonstrate this fundamental characteristic of quantum mechanics, effectively validating the de Broglie hypothesis regarding the wavelength of matter.
Academic Foundation
Born in Bloomington, Illinois, in 1881, Davisson attended Bloomington High School before enrolling at the University of Chicago on a scholarship. His academic trajectory was guided by Robert Millikan, who facilitated his transition to Princeton University as an instructor in 1905. He balanced teaching duties with doctoral studies under Owen Richardson, earning his Ph.D. in 1911 with research concerning the thermal emission of positive ions from alkaline earth salts.

Following his doctoral work, Davisson served as an instructor at the Carnegie Institute of Technology. During the First World War, he transitioned to industrial research within the Engineering Department of the Western Electric Company. This employment continued until 1925, when he joined the technical staff at the newly established Bell Telephone Laboratories, where he remained until his retirement in 1946. After leaving the laboratory, he accepted a visiting professorship at the University of Virginia.
The Davisson-Germer Experiment
In 1927, Davisson and Lester Germer observed that electrons scattering off the surface of a nickel crystal produced a diffraction pattern. This empirical result allowed for the first precise measurement of an electron's wavelength, confirming the relationship defined by the equation λ = h/p. By successfully measuring this wave property, Davisson provided essential evidence for the central tenets of quantum mechanics.
Accolades and Legacy
Davisson received numerous distinctions for his contributions to physics, including the Comstock Prize in 1928, the Elliott Cresson Medal in 1931, and the Hughes Medal in 1935. Following the Nobel Prize in 1937, he was awarded honorary doctorates from Purdue University, Princeton University, and the University of Lyon. He maintained memberships in the National Academy of Sciences, the American Philosophical Society, and the American Academy of Arts and Sciences. He died in Charlottesville, Virginia, in 1958, and is commemorated by the Davisson crater on the far side of the Moon.
