Cal Jammer was an American porn star. At a porn industry convention during the 1993 Consumer Electronics Show (CES) in Las Vegas, Jammer met then-stripper Jill Kelly, who he married and introduced to the porn industry. Kelly went on to become a major porn star, then director, and finally started her own successful studio. Kelly broke up with Jammer due to his many off-screen infidelities, which prompted Jammer to commit suicide on the road in front of Kelly's home in 1995 at the age of 34.
