In the fall of 1930 the Zurich mathematician Hermann Weyl returned to Göttingen as successor to David Hilbert. Soon thereafter he gave a speech in which he tried to explain to Göttingen students and rationalize to himself why he had chosen to come back to Germany after seventeen years at the Swiss Federal Institute of Technology in Zurich (Eidgenössische Technische Hochschule or ETH), where he had been content and productive. Weyl said:

Weyl not only wanted to get students to escape from the relative isolation of Zurich and to return to German culture, he also had to live up to his responsibilities as a member of the Göttingen thought collective and the elite of German science and try to wear Hilbert's mantle in a manner worthy of its previous owner. That he was expected to do so can be inferred from a letter in which Arnold Sommerfeld, one of the elder statesmen of theoretical physics in Germany, congratulated him on the appointment: “I am very pleased that you have decided to go to Göttingen. The opposite would have been a great disappointment to Hilbert.”
