Alfred Haar -(b. 10/11/1885 Budapest, d. 3/16/1933 Szeged, Hungary.) Mathematician: Introduced a measure on groups, now called the Haar measure, used by von Neumann, and other notables. In 1903, in his final year in school, Alfréd Haar won first prize in the Eötvös contest in mathematics. Haar travelled to Germany in 1904 to study at Göttingen and there he studied under Hilbert's supervision, obtaining his doctorate in 1909. Haar then taught at Göttingen until 1912 when he returned to Hungary and held chairs at the university in Kolozsvár (which is now Cluj in Romania), Budapest University and Szeged University. In fact after Word War I Kolozsvár was no longer in Hungary, so the University there had to move within Hungarian borders and it moved to Szeged, where there had previously been no university. Haar, together with Riesz, rapidly made a major mathematical centre from the new university. In 1932 he introduced a measure on groups, now called the Haar measure, used by von Neumann, and other notables.
