Psychology was reorganized at the Budapest University in several steps between 1945 and 1949. The paper shows on the basis of archival materials that in the beginning both conservative philosophers (Julius Kornis) who were in close professional contact with him, both newly appointed left wing professors (George Lukács) wanted to invite Géza Révész, founder of the Psychology Department in 1918–19, back to Budapest, who at the time was working in the Amsterdam University. After the failure of this invitation Dezső Hildebrand Várkonyi, originally from Szeged University, but at the time working at the Budapest University of Technology was invited for about a year. This was followed by the appointment of Lajos Kardos, the experimental psychologist as an associate professor and chair of psychology during the harsh years of ‘traversing the desert’ of Stalinist years. Kardos like other key players of the difficult years, Ferenc Mérei and Imre Molnár, were Jewish professionals socialized abroad due to the numerus clausus, the discriminatory university entrance regulations, who have become masters of network building as students of Leopold Szondi after returning to Hungary.
