Cathryn Damon

Damon was the elder daughter of Lee Frank Damon and Mary Cathryn Atwood. Her parents divorced and her mother married Walter A. Springer. Damon was born in Seattle and raised in Tacoma and graduated from Stadium High School. As a child, she felt insecure, saying: "I never thought I was attractive enough. I never thought I was good enough." She also felt as a child she was responsible for her parents' divorce. She moved to New York City at age 16 to pursue ballet.

Damon began her career as a ballerina, dancing in the Jacob's Pillow Dance Festival in Lee, Massachusetts, and performing with the Metropolitan Opera's dance company. Off-Broadway plays in which Damon appeared included The Boys From Syracuse. and The Secret Life of Walter Mitty. She appeared in several Broadway productions, including Shinbone Alley; Foxy; Flora the Red Menace; The Boys from Syracuse; The Last of the Red Hot Lovers; Sweet Bird of Youth; and The Cherry Orchard. During the 1967–68 season, she appeared in Dames at Sea at the Wayside Theatre and understudied the roles of both Mame Dennis and Vera Charles in Angela Lansbury's national tour of Mame. Damon became familiar to television viewers as middle-class Mary Campbell on the primetime spoof of daytime soap operas aptly entitled Soap from 1977 to 1981. However, many fans may not know that she was the third and final actress cast in the role. Producer Tony Thomas said, "Cathryn Damon was brilliant. A lot of people don't know this, but we recast that to put her in it." She later appeared with Soap co-star Eugene Roche on Webster from 1984 to 1986. The pair played Cassie and Bill Parker, Webster's landlords, on the hit series. Other television credits included guest roles on The Love Boat, Fantasy Island, Murder, She Wrote, Matlock, and Mike Hammer. Damon, along with costar and TV husband Richard Mulligan, won an Emmy Award for Soap in 1980 but could not appear in person to receive the award in person or give her speech, owing to an actors' strike. Mulligan referred to his late co-star (whom he affectionately called "Toots") and her strike-related absence when he received his second Best Actor Emmy more than a decade later for his role as Dr. Weston on the television series Empty Nest.

In August 1953, Damon married Richard Price Towers, an actor and singer, in New York City.

In 1986, Damon was diagnosed with ovarian cancer, but continued acting in small roles up until shortly before her death a year later at age 56, on May 4, 1987. She died in Los Angeles at Cedars-Sinai Medical Center. Her final role, as Elizabeth McGovern's mother in the movie She's Having a Baby with Kevin Bacon, was released posthumously. She is interred in Acacia Memorial Park near Seattle.
