Long Dong Silver is the pseudonym of a retired porn star. He appeared in several pornographic movies in the UK and US during the late 1970s and early 1980s, famed for the apparent size of his penis (18 inches / 45 centimeters). However, it was later revealed that his penis size was a fabrication that Daniel Mead had help in making from his photographer Jay Myrdal. Having been known as being one of the makeup artists for the film The Elephant Man, Myrtle created the prosthetic by utilizing a "flexible foam latex sleeve" that was "placed over Mead’s penis [and] glued down to his pubes" in order for him to pose during photo shoots.

His debut film was the low-budget Sex Freaks released in 1979, in which he co-starred with Vicki Scott. In 1982 he appeared with the legendary Seka in Beauty and the Beast, shot in America. His name is a reference to Long John Silver.

He received new fame in the wake of allegations of sexual harassment during the Clarence Thomas confirmation hearings in the U.S. Senate in 1991, as Anita Hill alleged that Thomas had mentioned to her that he was a viewer of Long Dong Silver's films
