Katherine Marie Helmond was born on July 5, 1929, in Galveston, Texas. After her parents divorced, she was raised by her mother, Thelma (nee Malone) Helmond, and her maternal grandmother, both of Irish Catholic descent. She attended Catholic school, and appeared in numerous school plays and pageants. She took a job at a local theater while still in high school, hammering and sawing the scenery, cleaning the bathrooms and pulling the curtain.
After her stage debut in “As You Like It”, she worked in New York theatres during the 1950s and 1960s. She operated a summer theatre in the Catskills for three seasons and also taught acting in university theatre programs. She made her TV debut in 1962 but had to wait another 10 years until her breakthrough came in the 1970s. She stayed busy on TV as well as on stage and earned a Tony nomination for “The Great God Brown” (1973) on Broadway. She honed her acting abilities with Alfred Hitchcock in Family Plot (1976) and in numerous TV series, notably in ABC’s cult sitcom Soap (1977), for which she had four Emmy nominations and a Golden Globe. On the big screen she starred in Brazil (1985) as Jonathan Pryce’s mother who is addicted to plastic surgery and snooping in her son’s messed-up life.
In 1983 she studied at the Directing Workshop of the American Film Institute and then directed four episodes of the series Benson (1979) as well as episodes of Who’s the Boss? (1984). She also picked up Emmy nominations for her role as Mona Robinson, a liberated grandmother in “Who’s the Boss?”, and as Lois in Everybody Loves Raymond (1996). Although Helmond was a bona-fide TV star since her “Soap” days, she continued working on stage in the 2000s and was acclaimed for her performances in “The Vagina Monologues”.
Katherine Helmond was married twice. She had no children. She turned to Buddhism in later years. She shared her time between her home in Los Angeles and homes in New York and London.
