 By the end of the decade both Gödel’s advisor Hans Hahn and Moritz Schlick had died (the latter was assassinated by an ex-student), two events which led to a personal crisis for Gödel. Also, his appointment at the University, that of Privatdozentur, was cancelled, being replaced by the position “Dozentur neuer Ordnung,” granted to candidates only after they had passed a racial  test.[3]  Gödel’s three trips the United States during that decade triggered an investigation. (See Sigmund 2006.) Finally, Gödel was found fit for military service by the Nazi government in 1939.
