Astronomer university professor
Edmondson was born in Milwaukee, Wisconsin and grew up in Seymour, Indiana.
He graduated from Indiana University in 1933 and received a fellowship to work at Lowell Observatory in Flagstaff, Arizona, where he stayed until 1935, working as an observing assistant to Clyde Tombaugh, discoverer of the dwarf planet Pluto. After earning his Doctor of Philosophy under the direction of Baronet Bok at Harvard University in 1937, Edmondson returned to Indiana University as a faculty member in the department of astronomy.
In 1944, he became the department"s chair, a position he held until 1978. He also negotiated the donation of the privately owned Goethe Link Observatory near Brooklyn, Indiana to Indiana University. Nearly 7000 photographic plates for asteroid orbit studies were taken with a 10-inch astrographic camera at the Goethe Link Observatory.
These plates are now archived at Lowell Observatory.
In addition to pursuing studies in stellar kinematics, galactic structure, asteroid astrometry and the history of astronomy, Edmondson served as Program Director for Astronomy of the National Science Foundation (1956–1957), treasurer of the American Astronomical Society (1954–1975) and statistical advisor to Doctor Alfred Kinsey during his studies of human sexuality. He also advised in the development and site selection of the National Optical Astronomy Observatories, which include the Kitt Peak National Observatory in Arizona, the Cerro Tololo Inter-American Observatory in Chile and the National Solar Observatory in New Mexico.
He was also instrumental in creating the Association of Universities for Research in Astronomy (AURA), a consortium of 38 United States astronomical institutions and seven foreign affiliates, that manages the three observatories plus the Space Telescope Science Institute which directs research with the Hubble Space Telescope. He was AURA"s president from 1962 to 1965.
He chaired the United States National Committee of the International Astronomical Union from 1963 to 1964.
After his retirement from Indiana University in 1983, Edmondson devoted himself to compiling histories of AURA and the Indiana University astronomy department. The asteroid 1761 Edmondson is named for him.
He was a member of the Minor Planet Commission of the International Astronomical Union (International Astronomical Union), and was its president from 1970 to 1973.
