At a 23 April 1984 press conference in Washington, D.C., Margaret Heckler, Secretary of Health and Human Services, announced that Gallo and his co-workers had discovered a virus that was the "probable" cause of AIDS. This virus was initially named HTLV-III. In the same year, Casper Schmidt responded to Gallo's papers with "The Group-Fantasy Origins of AIDS", published in the "Journal of Psychohistory". Schmidt posited that AIDS was not an actual disease, but rather an example of "epidemic hysteria", in which groups of people subconsciously act out social conflicts. Schmidt compared AIDS to documented cases of epidemic hysteria in the past which were mistakenly thought to be infectious. (Schmidt himself would later die of AIDS in 1994.)
