Jo Ann Pflug (born May 2, 1940, in Atlanta) is an American actress. For Hanna-Barbera, she was the voice of Susan Storm Richards aka the Invisible Woman on The Fantastic Four.
Despite the fact that a large portion of her role was left on the cutting room floor, Pflug still made a spectacularly sexy impression in the cult movie hit M*A*S*H (1970), which led to numerous TV co-star roles. Among the projects Pflug turned down were the film Slaughterhouse Five (1972), because she objected to the sexual content, and the TV series One Day at a Time.
Pflug was married to TV host Chuck Woolery from 1972 to 1980. She has one daughter, Melissa, from that marriage. She currently tours with her own motivational seminars and, since 2008, has been a society hostess in Savannah, Georgia.
