(written from a Production point of view)
Patricia "Pat" Westmore (born 4 June 1926; age 90) is a hair stylist who worked on the second and third seasons of Star Trek: The Original Series. Born into the famous Westmore family of Hollywood makeup artists, she was the aunt of Michael Westmore and Monty Westmore, aunt-in-law of June Westmore and great-aunt of McKenzie Westmore and Michael Westmore, Jr.
During her one-decade career as a Hollywood hair stylist, Westmore worked on a number of film and television projects, including The Rookie (1959, with Julie Newmar) and The Caretakers (1963, with Susan Oliver) and series such as The Adventures of Ozzie and Harriet.
According to Bjo Trimble, there was an ongoing hostility between Westmore and costume designer William Ware Theiss during their work on Star Trek. Often, when Theiss designed a costume, Westmore designed a hair style which would hide the most intriguing features of it. (These Are the Voyages: TOS Season Three)
