Menzel was the director of Harvard College Observatory from 1952-1966, and the Paine Professor of Practical Astronomy and Professor of Astrophysics. In 1966, he became a research scientist at the Smithsonian Astrophysical Observatory in Cambridge.
D ONALD H. MENZEL, one of the first practitioners of theoretical astrophysics in the United States, pioneered the application of quantum mechanics to astronomical spectroscopy.
(1901–76) Americanastrophysicist and solar astronomer. In the 1920s, with H. N. Russell, he established the field of theoretical astrophysics. In the 1930s he used quantum physics to interpret the Sun's flash spectrum, ascertaining the composition of the chromosphere and demonstrating the preponderance of hydrogen.
