Menzel, Donald Howard,

1901–76, American astrophysicist, b. Florence, Colo. From 1926 to 1932 he was with the Lick ObservatoryLick Observatory,
astronomical observatory located on Mt. Hamilton, Calif., near San Jose; the first mountaintop observatory in the world, it was founded through gifts made by James Lick in 1874–75 and came under the direction of the Univ.

 in Calif. In 1932 he joined the faculty at Harvard, where he became professor (1938) of astrophysics and director (1954) of the observatory. An authority on the sun's chromosphere, he discovered with J. C. Boyce (1933) that the sun's corona contains oxygen. With W. W. Salisbury he made (1941) the first of the calculations that led to radio contact with the moon in 1946.
