Frank Hagar Bigelow (August 28, 1851 in Concord, Massachusetts – March 2, 1924[1]) was an American scientist.
This service (1873–76; 1881–83) was interrupted for his theological studies, and for the short time (1880–81) after entering orders he was a rector in Natick, Massachusetts.
[1] Later he was professor of mathematics in Racine College, Wisconsin, assistant in the National Almanac office in Washington, D.C., and in 1891 he became professor of meteorology in the United States Weather Bureau in Washington.
His name is especially associated with an instrument for the photographic record of the transit of stars and with some novel studies by which the solar corona, the aurora, and terrestrial magnetism are shown to be associated.
His later writings were devoted to an isolated effort to reform meteorology through his publications.
