Scotty Bowers, who challenged the genteel image of studio-system Hollywood with a startling 2012 book in which he claimed to have arranged sexual liaisons for a long list of gay and bisexual stars and other show business figures, died on Oct. 13 at his home in Los Angeles. He was 96 .

Matt Tyrnauer, a documentarian whose 2017 film, “Scotty and the Secret History of Hollywood,” tells his story, said the cause was renal failure.

Mr. Bowers’s raunchy best seller, “Full Service: My Adventures in Hollywood and the Secret Sex Lives of the Stars,” written with Lionel Friedberg, left out few details as it told of his metamorphosis from gas-station employee to hookup-provider and sex partner to the rich and famous.

Men he knew from his military service during World War II began socializing at the gas station where he worked, and he paired those who were willing with the Hollywood people who found their way to him by word of mouth. Although he described catering to all sorts of sexual combinations, he said he had often surreptitiously provided willing men to male Hollywood figures and willing women to female ones in an era when being gay could ruin a career.
