A self-taught photographer from Zurich, Karlheinz Weinberger (Switzerland, 1921-2006) was a storekeeper for Siemens. In the mid-1940s, he published in the confidential homosexual magazine “Le Cercle”. Fascinated by the male body, he turned the photographic act into a parable of freedom. From 1958, Karlheinz Weinberger photographed with realism the Halbstarks, Swiss “greasers”. He studied them in the manner of an ethnologist, with empathy, curiosity and respect.
