Biography Timeline


He was born in Ghent, Belgium on January 21, 1880 to a family of artists. At his father's request he pursued, and in 1902, he received, the 1st degree of Civil Engineering Construction and began work as a civil engineer for the Brussels Department of Roads and Bridges. But his true vocation is not there, it was astronomy, and while performing his official duties as a civil engineer he joined volunteers at the Uccle Observatory. In 1904 he left civil engineering behind and joined the staff at the Royal Observatory of Belgium at Uccle.


In 1915, as World War I was raging, he was invited to come to work at Yerkes Observatory. He and his family made the dangerous trip across wartime Europe and settled permanently in the United States. He became a U.S citizen in 1922. He then began his work on double stars, comets, asteroids, and variable stars. In 1945 he was forced into retirement at Yerkes at the age of 65. Relieved of administrative duties, he became an even more active observer at Yerkes and at the McDonald Observatory. He made the frequent automobile trips between the observatories in Wisconsin and Texas without complaint.


He participated in numerous physically grueling astronomical expeditions to remote parts of the world throughout the late 1940s and 1950s. In 1952, at age 72, he traveled to Khartoum in Sudan and set up a 20' telescope to confirm Einstein's Theory of Relativity by noting the change in positions of the stars around the Sun during a total eclipse that year. His measurements were in agreement with Einstein's predictions. His travels to Sudan were the subject of a Time Magazine article.


In 1961 he published the Van Biesbroeck's star catalog. In this he cataloged a number of very faint stars, known by the VB numbers he assigned to them upon discovery. One notable star he discovered was the very small red dwarf secondary star, VB 10, also known as Gliese (GJ) 752B, of the primary star, Wolf 1055 (Gliese (GJ) 752A). This star was unique in that its absolute magnitude of 19 was the lowest of any star then known and still thought to be the lowest possible for any star. VB 10 was given the designation of Van Biesbroeck's Star to honor him for this work and his work with double stars.


In 1963 he came to the Lunar and Planetary Laboratory of the University of Arizona in Tucson Arizona to work under Gerard Kuiper. There he used his practical skills as a land surveyor to site the new Catalina Station now under the direction of Steward Observatory and that now houses the 1.6m Kuiper Telescope. He continued to observe and make contributions to astronomy up to a few months before his death. New scientific papers continued to be published under his name for several years afterward. He died on February 23, 1974 at the age of 94.

Family Life

George was born into a family mainly comprised of artists, yet his father urged him to earn a degree in Civil Engineering Construction; he later studied Theoretical Astronomy at Ghent University.
