Cynthia Szigeti (October 26, 1949 – August 10, 2016) was an American comic actress and acting teacher, known for her work at the Groundlings, an improv and sketch comedy troupe and school in Los Angeles, and the ACME Comedy Theatre. Her students included Will Forte, Lisa Kudrow, Joel McHale, Conan O'Brien and Julia Sweeney. Her professional acting credits included National Lampoon's European Vacation, as well as roles in Seinfeld and Curb Your Enthusiasm.
Szigeti went to Fairfax High School in Los Angeles. She later received her master's degree in acting from the University of California, Los Angeles (UCLA). Szigeti began her career by waitressing at the Pitchell Players improv club after graduating from UCLA. Her work at the club inspired her to enroll in improv classes at The Groundlings, the L.A. improv school, for $45 a month. Szigeti took the classes before successfully auditioning to become a full-time member of The Groundlings' main comedy troupe.
Cynthia Szigeti eventually left The Groundlings for The Comedy Store, a comedy club in West Hollywood, where she joined The Comedy Store Players alongside Taylor Negron, Martin Short and Robin Williams. In a 2009 interview, Szigeti spoke of the differences between performing within the comedy troupes of The Groundlings versus The Comedy Club, saying, "At the Groundlings it was all about wigs, rehearsals and costumes. At the Store, it was immediate, topical and edgy."
