 Clinton Davisson

A physicist whose route into research included a telephone-company job when he could not afford to continue at Chicago. He later worked at Bell Telephone Laboratories, retiring in 1946 after 29 years, and taught physics at Virginia in 1947–1949.^[ref] The Davisson–Germer experiment connects that industrial-laboratory work to electron diffraction and matter waves.

Clinton Davisson (1881–1958) was an American experimental physicist known for his significant contributions to the field of quantum mechanics. He is best known for the Davisson-Germer experiment, which he co-conducted in 1927 with Lester Germer. This experiment was pivotal in demonstrating the wave-like behavior of electrons, providing strong evidence for the wave-particle duality concept of matter, as predicted by quantum theory.
