J. Frank Schairer

J. Frank Schairer (13 April 1904, in Rochester, New York – 19 September 1970, near Point No Point, Maryland) was an American geochemist, mineralogist, and petrologist.

Schairer studied chemistry at Yale University with a bachelor's degree in 1925 and a doctorate in 1928. He was the president and one of the organizers of the undergraduate club "Yale Mineralogical Society" in 1923. In addition, he earned an M.S. in mineralogy. From 1927, he was a chemist at the Carnegie Institution Geophysical Laboratory in Washington, D.C. where he remained on the staff until mandatory retirement in 1969, when he became a part-time employee. He worked there with Norman L. Bowen in experimental petrology until Bowen's departure to the University Chicago in 1937. During World War II, the lab worked on military research (erosion in cannon and machine gun barrels). From the 1950s Schairer worked with Hatten Schuyler Yoder and Cecil Edgar Tilley on basalt fusions.

A mineral described by William F. Foshag in 1931 received the name schairerite in his honor.
