Bergen Davis (March 31, 1869 – June 30, 1958) was an American physicist and a professor at Columbia University.
[1] Davis's postgraduate work at the Cavendish Laboratory at Cambridge had prepared him to engage with the new physics which followed the work of scientists such as Albert Einstein, Max Planck, and Niels Bohr, concepts which he helped to introduce into the Columbia curriculum.
Among his many important works was a study of ionization and radiation potentials and the theory behind corona discharges.
[1] Davis served for many years as a consultant on X-rays to the staff of the Crocker Institute of Cancer Research at Columbia.
Irving Langmuir gave the Davis-Barnes Effect as an example of "pathological science" in his 1953 talk coining that phrase.
