Janet Fraiser was Chief Medical Officer of the newly formed Stargate Command. Starting as a captain, she was later promoted to major. She served for seven years up until her death in 2003.
Following her death, Fraiser's role as Chief Medical Officer was temporarily taken over by Dr. Brightman before Dr. Carolyn Lam - the daughter of the SGC's newest commanding officer, Major General Henry Landry - took over the position in 2005.
Fraiser was once married to a man who discouraged her from joining the United States Air Force. They were no longer together as of 1997 and, apparently, they never had any children. In her seven and a half years at the SGC she became one of the foremost experts on Goa'uld symbiotes, having created a symbiote tank to keep Junior in, and having had opportunities to dissect dead symbiotes. As the Chief Medical Officer of Stargate Command, Dr. Fraiser had the authority to overrule those of any rank whatsoever when it came to medical issue. She used this to get the SGC's main flagship team SG-1, into the infirmary on multiple occasions and ceasing experimental tests on SG team members. Her use of such authority once led SG-1 team leader, Colonel Jack O'Neill to call her a "Napoleonic power monger".
