Philip Taylor Kramer (July 12, 1952 - February 12, 1995) was a bass guitar player for the rock group Iron Butterfly during the 1970s. After this he obtained a night school degree in aerospace engineering, worked on the MX missile guidance system for a contractor of the US Department of Defense and later in the computer industry on fractal compression, facial recognition systems, and advanced communications. His disappearance on February 12, 1995 caused a mystery lasting four years.

In 1990 at the age of 38, Kramer co-founded Total Multimedia Inc. with Randy Jackson (brother of Michael Jackson) to develop data compression techniques for CD-ROMs. The firm claims it developed the first video compression capable of producing full motion video from a single speed CD-ROM in 1992. In 1994 the company was reorganized under bankruptcy and hired new leadership. Kramer continued working there until his death. Kramer co-developed SoftVideo based on fractal compression and he also claimed to work on a transmission project that would result in faster-than-light speed communications. The latter related to his father Ray's long-running family effort to discredit Albert Einstein's theories.

On February 12, 1995 he drove to Los Angeles International Airport to pick up an investor. He spent forty-five minutes at the airport but failed to meet the investor. Kramer did make a flurry of cell phone calls, including one to the police during which Kramer said, "I’m going to kill myself. And I want everyone to know O.J. Simpson is innocent. They did it."
