Pat Stevens was an American actress and voice actor. She is perhaps best known for her role as Nurse Baker on M*A*S*H and her role as the second voice of Velma Dinkley, both from 1976 to 1979. Stevens replaced Nicole Jaffe when Scooby-Doo moved from CBS to ABC. She was then replaced by Marla Frumkin midway through Scooby-Doo and Scrappy-Doo.
Stevens died after a long battle with breast cancer on May 26, 2010, at the age of 64.
