 Based on critical remarks Vogt had made about national socialism, a protective attitude towards Jewish coworkers at the institute, and rumors that he was a communist (spirited by his Moscow contacts), Vogt was pressed to early retirement by 1937.The Vogts moved to Neustadt in the Black Forest and established another private brain research institute, funded in part by the family of steel baron Krupp (who had already funded Vogt´s first private institute in Berlin) and by Vogt´s own funds.In 1937, Nazi physician Hugo Spatz, a pupil of Franz Nissl, became Vogt's successor as director of the KWI for Brain Research and head of the Neuroanatomy Department.
