Barbara Baldavin, who appeared on multiple episodes of the original Star Trek, and had a recurring role on the medical drama Medical Center, has passed away.

Classic sci-fi fans will remember Baldavin from her three appearances on Star Trek: The Original Series. Her first came on the first-season episode "Balance of Terror", which introduced the Romulans to the world. The episode opens with Kirk officiating a wedding between two of his crew members. The bride is Angela Martine, played by Baldavin. Unfortunately, due to a red alert, the wedding is interrupted. The episode finishes with Kirk and Martine talking once more.

She turns up again as Angela Martine (or Mary Teller — her character originally had another name, so she is referred to as both in this episode) in "Shore Leave", where she cowers from an advancing tiger and runs from aircraft gunfire.

Her third and final appearance, fittingly, was on the series finale episode "Turnabout Intruder", where Baldavin portrayed a communications officer. She had a deleted scene in a fourth episode, "Space Seed", but Baldavin's scene didn't make it to air.

Baldavin also appeared three times on Adam-12, notably once as the wife of a reckless officer, and again as Officer Malloy's date. She also had guest roles on Mannix, Barnaby Jones, Fantasy Island, and more.

In 1969 she joined the cast of Medical Center, first as a one-off character, then in a recurring role as Nurse Holmby.

Later in her career, she shifted to working in casting, much like her husband, who served as the casting director on Star Trek. Baldavin worked in the casting department for series like Trapper John, M.D., Dynasty, and Matt Houston.

She also served as an instructor for Dawn Wells' Film Actor's Boot Camp and was a close friend of the Gilligan's Island actress.

Baldavin was 85 years old.
