Douglas Murrell Cooper, known professionally as Tim Kramer (born 1958, died April 16, 1992) was a gay porn star, escort and health business owner best known for his role in the 1983 homoerotic film Gayracula.
Later, he attended high school in Columbus, Ohio, and upon graduation moved to Fort Lauderdale, Florida, where he began to model for Target Studios.
During the late seventies and early eighties, he made about a dozen feature-length films including Big Summer Surprise, Style, Giants II, Gayracula, I Do, Tony's Initiation, Men of the Midway, Heroes, Trick Time, Sun Stroke, and New Zealand Undercovers.
In a 1988 Advocate interview, Cooper spoke openly of the escort service he ran in Hollywood for many years: "That's where I made most of the money.
By the late 1980s, Cooper made fewer films and concentrated most of his energy on a health food store in West Hollywood.
