Larry Abbott is a makeup artist who assisted the makeup staff for the The Original Series episode "The Way to Eden".

Bjo Trimble recalled meeting Abbott while spending the day on the set of Here Come the Brides with Screen Gems special effects artist George Barr (who was living with the Trimbles at the time). Abbott and Barr were old acquaintances who both worked at Paramount on the episode "The Way to Eden", when, according to Trimble, "the extra makeup load required more craftspeople."
