Daniel Frost Comstock

Daniel Frost Comstock (August 14, 1883, Newport, Rhode Island – March 2, 1970, Concord, Massachusetts) was an American physicist and engineer.
He attained a B.S. from the Massachusetts Institute of Technology in 1904. He also studied in Berlin, Zürich, and Basel, where he attained his Ph.D. in 1906. At the University of Cambridge (1906–1907) he studied under J. J. Thomson. Beginning in 1904 he was a member of the faculty at MIT in theoretical physics (assistant professor 1910–1915; associate professor 1915–1917).
Comstock is most well known as the co-founder of the company Kalmus, Comstock & Westcott, and of Technicolor Motion Picture Corporation, which developed the second major color film process, after Britain's Kinemacolor, and the most widely used color motion picture process in Hollywood from 1922 to 1952.
Comstock also published some theoretical papers in the fields of electrodynamics (1908), special relativity (1910a), and emission theory (1910b).
