LifeEdit

Wilhelm Anderson was born in Minsk (now in Belarus) into a Baltic German family.[1] His younger brothers were the well known mathematician Oskar Anderson (1887-1960) and the folklorist Walter Anderson (1885-1962). Anderson spent some of his youth in Kazan, where his father Nikolai Anderson (1845-1905) was a university professor for Finno-Ugric languages.[2]

He studied at the University of Kazan, where he graduated from the department of mathematics and science in 1909. Between 1910 and 1920, he worked as a physics teacher first in Samara and then from 1918 in Minsk.[3] Together with his brother Walter Anderson, he moved to Tartu (Estonia) in 1920. At the University of Tartu, he first gained a Masters degree in Astronomy in 1923 and then a Doctorate in 1927.[4] In 1934 he became a habilitation candidate at the university, and in 1936 he received an assistant professorship there, but early in 1939 he suffered a mental breakdown which left him unable to work.[1]. Like the majority of Baltic Germans, he was resettled to Germany in late 1939, where he died in the Sanatorium of Meseritz-Obrawalde, shortly thereafter. It has been suggested that Anderson may have been a victim of the National Socialist "euthanasia" program.[1]

Anderson is probably best known for his work on the mass limit for a white dwarf (one of the final evolutionary states of a star),[5] extending Edmund Stoner's earlier work [6] by relativistic amplification (1929, Tartu),[7][8][1] which was in turn further improved by Stoner.[9][10] The Stoner-Anderson equation of state, a result of Anderson's correspondence with Stoner, is named after him.[11] The white dwarf mass limit was further refined by Subrahmanyan Chandrasekhar and is now known as the Chandrasekhar limit.[12][9]
