Editing Gerhard Gentzen (section)

==Life and career==
Gentzen was a student of [[Paul Bernays]] at the [[University of Göttingen]]. Bernays was fired as "non-[[Aryan]]" in April 1933 and therefore [[Hermann Weyl]] formally acted as his supervisor. Gentzen joined the [[Sturmabteilung]] in November 1933, although he was by no means compelled to do so.{{sfn|Menzler-Trott|2007|p=52}} Nevertheless, he kept in contact with Bernays until the beginning of the [[Second World War]]. In 1935, he corresponded with [[Abraham Fraenkel]] in Jerusalem and was implicated by the Nazi teachers' union as one who "keeps contacts to the [[Chosen People]]." In 1935 and 1936, [[Hermann Weyl]], head of the Göttingen mathematics department in 1933 until his resignation under Nazi pressure, made strong efforts to bring him to the [[Institute for Advanced Study]] in Princeton.

Between November 1935 and 1939 he was an assistant of [[David Hilbert]] in Göttingen. Gentzen joined the [[Nazi Party]] in 1937. In April 1939, Gentzen swore the [[Hitler Oath|oath of loyalty]] to [[Adolf Hitler]] as part of his academic appointment.{{sfn|Menzler-Trott|2007|p=119}} From 1943 he was a teacher at the German [[Karl-Ferdinands-Universität|Charles-Ferdinand University of Prague]].{{sfn|Folta|Šišma}} Under a contract from the [[Schutzstaffel|SS]], Gentzen worked for the [[V-2]] project.{{sfn|Menzler-Trott|2007|p=238}}

Gentzen was arrested during the [[Prague uprising|citizens uprising]] against the occupying German forces on 5 May 1945. He, along with the rest of the staff of the German University in Prague, were detained in a Soviet prison camp, where he died of starvation on 4 August 1945.{{sfn|Menzler-Trott|2007|p=273 ff}}<ref>{{MacTutor Biography|id=Gentzen}}</ref>
