Helmut Hasse (1898-1979) mathematician Helmut Hasse was one of Emmy Noether's colleagues at the University of Göttingen, prior to her emigrating to the United States in 1933. With Hasse and Richard Brauer, Noether published fundamental results in R. Brauer, H. Hasse, and E. Noether, "Beweis eines Hauptsatzes in der Theorie der Algebren," Jounal für die reine und angewandte Mathematik After serving in the German navy during World War I, Hasse matriculated at the University of Göttingen in 1918. There he attended lectures of Edmund Landau, David Hilbert, Emmy Noether, and Erich Hecke. In 1820, Hasse went to Marburg, and under the direction of Kurt Hensel, discovered what is now known as the Hasse principle, or "local-global" principle, in algebraic number theory. Hasse held positions at the universities in Kiel, Halle, and Marburg prior to 1933. In that year, drastic changes took place in Germany and German universities. Jewish academics, including Emmy Noether, were deprived of their academic positions, and they left for other countries. At Göttingen, Hilbert had retired in 1930, and his chair, considered the foremost in mathematics in Germany, was filled by Hermann Weyl. With the troubles of 1933, Weyl resigned, and Helmut Hasse was appointed to the chair. The following year, Hasse became director of the Mathematical Institute at Göttingen, signifying both his eminence as a mathematician and political acceptability to the Nazi regime. Much is written in the references cited below about Hasse's views and activities during those difficult times.

Helmut Hasse - Emmy Noether Deutsch Correspondence Edited and commented by Franz Lemmermeyer and Peter Roquette The Hasse-Noether files contain all letters from the correspondence between Helmut Hasse and Emmy Noether, as they are preserved in the University Library of Göttingen. There are 82 letters from the years 1925-1935. In addition we have included 5 letters from the correspondence of Hasse with Hermann Weyl and with Richard Brauer, which had been exchanged in April 1935, shortly after the death of Emmy Noether . Unfortunately, the correspondence Hasse-Noether is preserved on one side only, i.e., the letters from Noether to Hasse. The letters from Hasse to Noether are probably lost, except 3 letters of which Hasse had made a copy for himself. Because of the lost letters of Hasse to Emmy Noether, many parts of Noether's text which refer to Hasse's letters seem incomprehensible on first sight. However we have been able, by using other sources, to clear up most of the doubtful passages. In consequence we are planning to supplement Noether's letters by detailed comments. Some comments are already included in the following version but it will take some time until all our comments are completely inserted. Nevertheless it seems worthwhile to present these letters to the mathematical public now already, as an important historic document of the history of algebraic number theory. More comments will be inserted in due time.

HELMUT HASSE Return to Previous Screen sources Early years Hasse was born on 25 August 1898 in Kassel. Like Dirichlet, Kummer and his future mentor Kurt Hensel, he was a distant relative of the composer Felix Mendelssohn­Bartholdy. He left school in 1915 with a "Notabitur" and served in the German navy. From autumn 1917 onwards, based at Kiel, he was able to attend the lectures of O. Toeplitz. In 1918 he matriculated at Göttingen, where his teachers included E. Landau, D. Hilbert, E. Noether (whose lectures he found at first totally unintelligible) and E. Hecke (whose lucid style he admired). In 1920 - Hecke had gone to Hamburg - Hasse went to Marburg where he completed his studies under Kurt Hensel, whose work on p ­adic numbers was to have a profound influence on him. It was at this time that he worked out the "local­global principle" now known by his name, and applied it with great success to the study of quadratic forms over the rationals, where both the representability of a number by a given form and the equivalence of two forms can be decided by local information alone. These two questions became, respectively, the focus of his doctoral dissertation "Über die Darstellbarkeit von Zahlen durch quadratische Formen im Körper der rationalen Zahlen"
