On April 6, 1976, two gay liberation organizations "zapped" (demonstrated at) the New York Academy of Medicine, in New York City, which was hosting a panel on homosexuality sponsored by the Association for Psychoanalytic Medicine, and featuring three anti-homosexual psychiatrists, Irving Bieber, Charles Socarides, and Lionel Ovesey. This exhibit, originally published on OutHistory in 2016, introduces the zap.
