Joyce DeWitt portrayed the level-headed Janet Wood on 'Three's Company,' which ran for eight seasons between 1976 until 1984.
'Three's Company' followed the lives of three single roommates, Jack Tripper (John Ritter), Janet Wood (Joyce DeWitt) and Chrissy Snow (Suzanne Somers), their living arrangement and sexual exploits. At the time of the show's debut in 1976, co-ed living was still somewhat taboo and the trio told the landlord Stanley Roper (Norman Fell) that Jack was gay, while the landlord's wife Helen (Audra Lindley) knew what 'the kids' were doing.
When Somers was written off the show in 1981, her character Chrissy Snow was sent to care for her sick mother in Fresno and was temporarily replaced by Chrissy's cousin Cindy Snow (Jenilee Harrison) before their permanent roommate, nurse Terri Alden (Priscilla Barnes) moved in.
Lindley and Fell went on to star in the spinoff 'The Ropers,' which ran between 1979 and 1980 on ABC, which showed the couple moving from their 'Three's Company' home to live in the fancier Cheviot Hills community and sold the building. The new owner's brother Ralph Furley (Don Knotts) took over as the landlord.
DeWitt grew up in Indiana and received her master's degree in theater from the University of California at Los Angeles (UCLA).
Following the success of 'Three's Company,' DeWitt went on to appear in an episode of 'Finder of Lost Loves' in 1984 and quit acting for several years. She next appeared in a stage production of 'Noises Off' in 2991.
The 62-year-old actress has also since made appearances on 'Pinky and the Brain,' 'Cybill' and 'Living Single.'
She went on to co-produce and host the 2003 NBC made-for-TV movie, 'Behind the Camera: The Unauthorized Story of Three's Company.'
Her most recent roles were in the 2008 indie film, 'Failing Better Now' and on-stage in the 2011 play, 'Miss Abigail's Guide to Dating, Mating and Marriage' in New York.
