23 February 1929 |
|Notable awards||Gruber Foundation Cosmology Prize (2014)|
Jaan Einasto (born 23 February 1929, in Tartu) is an Estonian astrophysicist and one of the discoverers of the large-scale structure of the Universe. He is a patriotic Estonian; the name "Einasto" is an anagram of "Estonia" (it was chosen by his patriotic father in the 1930s to replace the family's German name).
Born in Tartu, he attended the University of Tartu, where he received the Ph.D. equivalent in 1955 and a senior research doctorate in 1972. From 1952, he has worked as a scientist at the Tartu Observatory (1977–1998) Head of the Department of Cosmology; in 1992-1995, he was Professor of Cosmology at the University of Tartu. For a long time, he was Head of the Division of Astronomy and Physics of the Estonian Academy of Sciences in Tallinn. Einasto is a member of the Academia Europaea, the European Astronomical Society and the Royal Astronomical Society; he has received three Estonian National Science Awards.

In 1974, in a seminal work with Kaasik and Saar at the Tartu Observatory, Einasto argued that "it is necessary to adopt an alternative hypothesis: that the clusters of galaxies are stabilised by hidden matter." This was a key paper in recognizing that a hidden matter, i.e., dark matter, could explain observational anomalies in astronomy.

- Vera Rubin - her discovery of "flat rotation curves" is the most direct and robust evidence of dark matter.

In the 1930's [the] Estonian government started a campaign to change German names to Estonian ones. So our family name was also changed. My father was a real patriot of Estonia, so he invented the name "Einasto", which is a permutation of "Estonia". The name was patented, so nobody else can have this name. In this respect our family name is unique.
