Don S. Davis, a college professor who found a second career as a character actor, gaining notice for his roles in TV's "Stargate: SG-1" and "Twin Peaks," died of a heart attack June 29 at his home in Gibsons, Canada. He was 65.
Davis was teaching theater arts at the University of British Columbia in Vancouver in the early 1980s when he decided to pursue acting as a profession.
A native of the Missouri Ozarks who had served in the U.S. Army, Davis drew upon those experiences in his frequent portrayals of authority figures on television and film. He had a regular role as Gen. George S. Hammond on the science-fiction TV series "Stargate: SG-1" from 1997 to 2006 and a recurring role as Maj. Garland Briggs on the quirky "Twin Peaks" in the early '90s. He also appeared periodically as Scully's father in "The X-Files" TV series about FBI agents investigating unsolved cases.
"I like sci-fi because it's really one of the last places or genres that has clearly defined good and evil, and it's a place where you can have heroes without them having to be overly flawed," Davis told the Press of Christchurch, New Zealand, last year.
