Smith's father, Kenneth Smith was employed by Paramount Studios during the 1930s and 1950s, where he was employed as a carpenter, assistant camera operator, and eventually stage hand. Smith, herself, was very briefly married to bodybuilder turned actor Steve Reeves.
Outside of Star Trek, Smith is best known for her role as Julie Conrad Bauer on the soap opera Guiding Light from 1962 through 1965. Afterward, she acquired a recurring role on Our Private World, during which she co-starred with fellow Trek alumni Nicholas Coster, Michael Strong, and Kenneth Tobey. She went on to appear on such television programs as The John Forsythe Show (with Darleen Carr), The Virginian (in an episode also guest-starring Andrew Prine), The Big Valley (working with the likes of Hal Baylor, Walker Edmiston, Jon Lormer and Michael Strong), Mannix (in an episode with Steve Ihnat), The Bold Ones: The Lawyers (also with Ihnat), Gunsmoke (three episodes), Bonanza (two episodes, including one with Bill Zuckert), and The Flying Nun (with Michael Pataki). On stage, she performed on Broadway in the plays The Pleasure of His Company and Ash Wednesday. She won a 1966 Theatre World Award for her role in the latter play, on which she also co-starred with Kenneth Mars.
During the 1970-71 season, Smith co-starred with fellow Original Series guest actors Stephen Brooks and Skip Homeier in The Interns. In 1972, she reunited with her "Turnabout Intruder" co-star William Shatner for an episode of Owen Marshall: Counselor at Law (which also featured Bill Quinn). Smith followed this with guest spots on Hawaii Five-O (with Monte Markham and Madlyn Rhue), The Rockford Files, Starsky & Hutch (starring David Soul) and Columbo (starring Ray Milland), before she retired from acting.
