In the years 1912 and 1913 there occurred an epistolary encounter between the founding father of psychoanalysis and the young Hans Blüher who had been active in the Wandervogel movement, a German youth movement with strong traditionalist and nationalist leanings. Their correspondence centered around the evaluation of male homosexuality, a point on which Freud and Blüher were not in entire agreement. In his introduction Neubauer outlines the intellectual nub of this debate and sketches Blüher's later career and his gradual transformation into a biologistically motivated anti-Semite completely and utterly disowned by Freud.
