Curtis Judson Humphreys (17 February 1898 – November 1986) was an American physicist born in Alliance, Ohio, USA. He was chief of the Radiometry Section of the U.S. Navy during the 1940s. He is famous for discovering the Humphreys series of the hydrogen atom.
Humphreys married Jeanette Mae Raum, with whom he had a son Richard.
He was involved in the Spectroscopic Program covering the NBS and U.S. Naval Ordnance Laboratory, Corona, CA, experiences. His inventions significantly advanced the techniques of radiometry and spectrophotometry. He credited the Corona Lab program with the establishment of the atomic wavelength standard in the infrared.
Humphreys attended the Rydberg Centennial Conference on Atomic Spectroscopy in 1954, which at the time was the most distinguished group of spectroscopic and atomic physicists ever assembled, and included the eminent Niels Bohr.
He corresponded with William F. Meggers while in Michigan in 1928.
Awards and Accomplishments
- He received the Naval Award for Achievement in Science.
- He was awarded the William F. Meggers Award in 1973.
- He was listed in "World Who's Who in Science" in 1968.
Humphreys is the author of many scientific research articles and books including First spectra of neon, argon, and xenon 136 in the 1.2-4.0 µm region, written in 1973 while he was at Purdue University, Lafayette, Indiana.
