Howard Ziehm (born April 7, 1940) is a retired American director, director of photography, producer and writer of adult movies.
Ziehm is regarded as a pioneer in the porn industry.
His 1970 film Mona: The Virgin Nymph was the first 35mm adult feature film that was nationally released in theaters.
He was inducted into the XRCO (X-Rated Critics Organization) Hall of Fame for his work in 1986.
Ziehm's best-known film is Flesh Gordon, a 1974 soft sex spoof of the Flash Gordon serials.
It was nominated for a Hugo Award for "Best Dramatic Presentation" in 1975 and is now celebrated as a cult classic.
The film is also notable for providing the training grounds for several now-famous special effects artists like Rick Baker, Dennis Muren and Greg Jein; animator Jim Danforth also worked on the movie.
