mathematician university professor
He was born in Kassel, and died in Ahrensburg.
After serving in the navy in World War I, he studied at the University of Göttingen, and then at Marburg under Kurt Hensel, writing a dissertation in 1921 containing the Hasse–Minkowski theorem, as it is now called, on quadratic forms over number fields.
He then held positions at Kiel, Halle and Marburg. He was Hermann Weyl"s replacement at Göttingen in 1934. Politically, he was a right-wing nationalist and applied for membership in the Nazi Party in 1937, but this was denied to him due to his Jewish ancestry.
After the war, he briefly returned to Göttingen in 1945, but was excluded by the British authorities.
After brief appointments in Berlin, from 1948 on he settled permanently as professor in Hamburg. He collaborated with many mathematicians, in particular with Emmy Noether and Richard Brauer on simple algebra, and with Harold Davenport on Gauss sums (Hasse–Davenport relations), and with Cahit Arf on the Hasse–Arf theorem.
In 1933 Hasse had signed the Loyalty Oath of German Professors to Adolf Hitler and the National Socialist State.
