The Caldron (often misspelled Cauldron), at 853 Natoma Street in San Francisco, in the South of Market St. area, was a gay sex club which opened in 1980 and closed in 1984.[1] It was called "the epitome of the uninhibited, abandoned, 'sleazy' sex club."[2]
Located in a converted warehouse, the site was unabashedly a place where men went to have sex. Patrons were required to be naked except for footwear; a clothes check was provided.[3] Like other similar venues, it had no alcohol license; patrons brought their own alcohol, usually beer, and this was stored in a cooler and patrons given chits that they could turn in for a can of the brand of beer they had brought. It was described as "exemplary" as one of the first venues to promote safe sex as the AIDS crisis hit.[4][5]
The owners were Hal Slate[6] and Stephen Gilman.[7] The club had two bathtubs for those who wanted to be urinated on. The lights were not dimmed.[8] There were tables and benches for having sex on, and slings.[9] The Caldron featured thematic nights: Tuesdays were for water sports, Thursday for fisting; it also set aside nights for masturbation. A poster announcing its First Anniversary Orgy has been preserved.[10] The name Caldron, according to owner Gilman, was the I Ching's commentary on itself.
Slate and Gilman were members of the San Francisco Gay Men's Chorus, which after Monday chorus rehearsals sometimes repaired to the Caldron for a private party. Opera music was the background.[11][12] The San Francisco Jacks, a masturbation club, met at the Caldron.[13]
