(written from a Production point of view)
Kenneth David Ebling is an actor who worked as photo double for Brent Spiner in the Star Trek: The Next Generation seventh season episode "Inheritance" in 1993. Spiner had to play two characters in this scene and a photo double was required for the "over the shoulder" shots. Ebling received no credit for his work and was identified by the name tag of the costume which was sold off on the It's A Wrap! sale and auction on eBay. 
Ebling played the coach in the 1995 Red Shoe Diaries episode Swimming Naked, a marine technician in the television thriller OP Center (1995, with Sherman Howard, France Nuyen, Todd Waring, John Savage, Kim Cattrall, and Peggy Miley), a french matairde in several episodes of the drama series Port Charles, a stunt skater in an episode of Diagnosis Murder, and an Arizona student in Milos Forman's drama Man on the Moon (1999, with Vincent Schiavelli, Caroline Gibson, Gene LeBell, Rob Steiner, Kelly Cooper, Christopher Lloyd, and Tracey Walter).
