Taken from Gateworld

With great sadness we must report that veteran actor Don S. Davis passed away on June 29, 2008. He was 65 years old.

Don co-starred on Stargate SG-1 for the show’s first seven years, helping to launch the enduring science fiction franchise. Davis played Major General George Hammond, base commander and a father figure to many of the show’s characters.

He is also well-known for his portrayal of Major Garland Briggs in Twin Peaks.

Off-screen, Don was beloved by the show’s cast and crew. He departed the show in 2003 due to a medical condition that restricted his workload, but returned for several guest appearances on SG-1 and Stargate Atlantis in the following years. Don worked hard to improve his health, and continued to work both on screen and off until his death.

I only just read this tragic news a few minutes ago, such a great actor who everyone will know worked on Stargate for many years, a good artist as testament from his website and from all the people who met him, such a happy person. All the best to the family and friends through what is a difficult time.
