(written from a Production point of view)
Gimpel was a dancer in Los Angeles before being an extra for Central Casting. One of those jobs was for the Star Trek: The Original Series first pilot "The Cage", given "they knew I could handle costume work and stuff, from dancing." In "The Cage", Gimpel played a Talosian. The costume work led her to being cast as the M-113 creature in "The Man Trap", filming her scene on Friday 24 June 1966 at Desilu Stage 9. Gimpel also served as an extra in later episodes.  According to her own recollections, she also worked on both Star Trek: The Next Generation and Star Trek: Enterprise. (Portal47)
