Frances Stewart was a member of the medical staff of the Enterprise-C in the late 24th century. She was on duty when Saavik, in the throes of pon farr, was taken aboard the Enterprise as a patient. Dr. Stewart took charge of Saavik's medical care and was one of the members of the crew sent along in a shuttlecraft to accompany Saavik to Vulcan. Stewart therefore became one of the few members of the Enterprise crew to survive, as their shuttle left the ship before its fateful battle with the Romulans at Narendra III.
