Live and act

Hopf studied physics and mathematics in Berlin and Munich from 1902 to 1909. In Munich, Hopf was one of Arnold Sommerfeld's students , with whom he also received his doctorate. Hopf became an assistant to Albert Einstein and came to the TH Aachen in 1911 as an assistant to the then professor of mechanics . Theodore von Kármán took over the chair. Hopf completed his habilitation under Kármán in 1914 and taught as a private lecturer until 1916. In 1923 he was appointed full professor for mathematics and mechanics at the TH Aachen.

In the spring of 1933, denunciation measures by the student body began at RWTH Aachen University . The ASTA ( General Student Committee ) and the student leaders sent the denunciation committee specially set up for this purpose, consisting of Hermann Bonin , Hubert Hoff , Felix Rötscher , Adolf Wallichs , and Robert Hans Wentzel, about which of the lecturers and professors were not of Aryan descent or were supposed to be actually had an undesirable political attitude. According to the law for the restoration of the civil service due to his Jewish origin, Hopf was supposed to be together with the other non-Aryan professors Otto Blumenthal , Arthur Guttmann , Walter Maximilian Fuchs , Theodore von Kármán , Paul Ernst Levy , Karl Walter Mautner , Alfred Meusel , Leopold Karl Pick , Rudolf Ruer , Hermann Salmang and Ludwig Strauss had their teaching license withdrawn from September 1933. Despite a letter from his incumbent rector Paul Röntgen to the Reich Commissioner in the Ministry of Education, Bernhard Rust , to be allowed to keep him, Hopf was finally dismissed on January 22, 1934.

In 1939 Hopf received an appointment at Cambridge University and emigrated to England. Shortly afterwards he went to Trinity College in Dublin. He died of thyroid failure in Dublin on December 21, 1939.
