Betty McGuire, the actress who played Kate Malone on the ABC sitcom ‘Growing Pains,’ died on October 8, 2026. She was 100.
She died of natural causes at the Motion Picture & Television Fund campus in Woodland Hills, California. Keith Gerchak, her power of attorney, confirmed her death.
McGuire worked for about seven decades. She began on the Broadway stage in the 1950s. She toured in some of the best known musicals of her time. Then she built a long career in television. Many viewers knew her as the mother of Maggie Seaver and the grandmother of four children on one of the most popular family comedies of the 1980s. She had no surviving family members.
Early years and a start on stage
McGuire was born in Bridgeport, Connecticut. She chose performing as her trade and stayed with it for most of her life.
McGuire made her Broadway debut in 1955. She played Rebecca in the musical ‘Plain and Fancy.’ The show was set among the Amish of Pennsylvania. It gave her a first credit on the biggest stage in American theater.
She returned to Broadway twice more in the decade. In 1956 she appeared in ‘Happy Hunting.’ In 1958 she appeared in ‘Oh Captain!’ Those productions put her in rooms with major names. Her castmates and colleagues included Ethel Merman, Barbara Cook, Bea Arthur and Tony Randall.
McGuire also worked on the road. She appeared in touring productions of ‘Auntie Mame,’ ‘Gypsy’ and ‘Oliver!’ Touring is tough work. A company packs up, moves to a new city and performs again within days. A performer learns quickly to hold a crowd, night after night.
Moving to television
McGuire’s television career began in 1973. Her first credit was an episode of ‘The Doris Day Show.’
Over the next several decades she became a familiar face in guest casts. Her list of credits is long. It includes ‘Little House on the Prairie,’ ‘Hart to Hart,’ ‘Charlie’s Angels,’ ‘Columbo,’ ‘MacGyver’ and ‘Moonlighting.’ She appeared in ‘Murphy Brown,’ ‘Murder One’ and ‘7th Heaven.’ She also took roles in ‘Star Trek: Deep Space Nine,’ ‘ER’ and ‘CSI: Miami.’
She had multi-episode runs on two major dramas. One was ‘Hill Street Blues.’ The other was ‘Falcon Crest.’ Most of her other roles lasted a single episode. Those small parts are the daily work of a character actor. They rarely bring fame. They do bring steady employment, and McGuire kept at it for years.
Kate Malone on ‘Growing Pains’
Her best known role came from ‘Growing Pains.’ The series aired on ABC from 1985 to 1992. Neal Marlens created it. The show ran for seven seasons and 166 episodes.
The story centered on the Seaver family. Jason Seaver, a psychiatrist played by Alan Thicke, worked from home. That allowed his wife Maggie, played by Joanna Kerns, to return to her career as a reporter. They raised four children. Kirk Cameron played Mike. Tracey Gold played Carol. Jeremy Miller played Ben. Ashley Johnson played Chrissy.
McGuire played Kate Malone, Maggie’s mother. That made her the grandmother of all four Seaver children.
Kate was a recurring character, not a lead. McGuire appeared in 12 episodes across the run of the series. She first showed up in the first season episode ‘Be a Man.’ She came back in the final season for ‘Home Malone.’ Her appearances were spread over the entire life of the show, and that gave Kate a lasting place in the family.
The series became a fixture of its decade. Families gathered to watch it on weeknights. The theme song, ‘As Long as We Got Each Other,’ stayed in the memory of a generation. A young Leonardo DiCaprio joined the cast in its later years. Through all of it, McGuire gave the Seavers a link to an older generation.
The show has not faded. Episodes are available to stream for free on YouTube. New viewers can still meet Kate Malone there.
Work on film
McGuire also took parts on the big screen. She appeared in ‘Coma,’ the 1978 thriller directed by Michael Crichton. She also appeared in ‘Cheech & Chong’s Up in Smoke,’ the 1978 comedy that launched a string of films for the duo.
The two titles could hardly be more different. One was a tense medical mystery. The other was a loose stoner comedy. McGuire’s presence in both shows the range a working actress needed in those years.
Service to her community
McGuire did not stop giving once her acting slowed. In later life she volunteered at the Coalition for Economic Survival legal clinic in Los Angeles. She worked as a receptionist and as an advocate. The clinic helps low-income tenants who face eviction.
That work puts a person in front of families at a frightening moment. Losing a home is a crisis. A friendly voice at the front desk can make the first step easier. McGuire offered that voice well into her senior years.
Life at the Motion Picture & Television Fund
Since 2017, McGuire had lived at the Motion Picture & Television Fund Home in Woodland Hills. It is a retirement community built for people from the entertainment industry. Many residents there spent their careers on stage, on set and behind the camera.
McGuire stayed active there. In her 90s she hosted GabFest, a segment on ‘NBC Nightly News with Lester Holt.’ The segment put the spotlight on her fellow residents and their stories. She had spent a lifetime in front of audiences. Now she used that skill to help others take their turn.
She was also still working in a sense. A woman who first stepped onto a Broadway stage in 1955 was hosting a talk show decades later. Few performers can say their career ran that long.
Her passing
McGuire died on Thursday, October 8, at the Motion Picture & Television Fund’s Wasserman Campus in Woodland Hills. The cause was natural. She was 100 years old.
Her representative and Gerchak confirmed her death. News reached the public ten days later, on Sunday, October 18. Trade publications and entertainment outlets noted her passing that day and the next.
She had no survivors. No spouse, children or siblings were named in the reports. Information about a memorial service has not been made public.
Her work remains on screen for anyone who wants to find it. Her years on Broadway remain in cast lists and theater history. And, her generosity remains with the people she helped. Betty McGuire was 100 years old, and she used nearly all of them well.
