American photographer and pornographer Bob Mizer was BOTD in 1922. Born in Idaho, his parents separated when he was a child, and he moved to Los Angeles with his mother. In 1942, he began working Frederick Ko’Vert, a former silent film star turned male physique photographer. Mizer began publishing his own photographs, often having sex with his well-oiled muscular models. In 1945, he opened his own studio, the Athletic Model Guild, in his mother’s living room, and published the first issue of Physique Pictorial, featuring well-oiled muscle men in Greco-Roman poses and playing the roles of sailors, wrestlers and cowboys. His mother assisted with his photography, on the condition that the models wear posing pouches. He photographed thousands of men, filming many of his photo sessions, and also published the early erotic illustrations of Tom of Finland and George Quaintance. After his mother’s death in 1964, he began photographing his models fully naked, posing them in master/slave and bondage scenarios. He used a series of codes to record information about his models’ penis size and sexual preferences, imprinting these in his published photographs and loaning out his models for sex. He was arrested and imprisoned several times for distributing obscene material, photographing minors and running a prostitution ring. His work became more widespread during the gay liberation movement, influencing younger generations of gay artists, including Kenneth Anger, David Hockney, Francis Bacon, Andy Warhol and Robert Mapplethorpe. Many of his models went on to Hollywood careers, including Alan Ladd and Arnold Schwarzenegger. Mizer continued working until his death in 1992, aged 70. Many of his photographs and films was destroyed after his death, though a substantial archive is held by the Bob Mizer Foundation. His life and work was recreated in Thom Fitzgerald‘s 1998 docudrama Beefcake, starring Daniel MacIvor as Mizer.
