Lauren Chapin’s death hits family first and viewers who grew up with Kathy "Kitten" Anderson

Her son, Matthew Chapin, posted on Facebook on February 24 saying his mother had died after a long, hard-fought five‑year battle with cancer. He wrote that he was at a loss for words and asked people to keep his sister and family in their thoughts as they go through an incredibly difficult time. Fans responded with condolences on the same social thread, one message offering strength and hoping cherished memories bring some peace.

Event details and timing

Coverage published on February 25, 2026 notes that Chapin was 80 and that she died following the lengthy cancer fight her son described. Some accounts described the death as occurring on a Tuesday and linked the announcement to the Facebook post from Matthew Chapin the day before.

Where the role fit in her life and the show's run

Chapin is best known for portraying Kathleen "Kitten" Anderson on Father Knows Best for six seasons. She was hired for that role when she was 9 after earlier appearances, including a 1952 television episode and a 1954 film appearance. The series itself ran from October 1954 through May 1960, with two stints on one network sandwiching a run on another; reruns appeared in primetime for a couple of years on a third network and the show continued in syndication for decades. The cast reunited for two television specials in 1977. Chapin won the part partly because she resembled one of the family patriarch's daughters, and the role followed a radio version that had featured a different performer in the part.

Career highlights and a long acting hiatus

After Father Knows Best ended, Chapin appeared five months later on General Electric Theater alongside Steve Allen and Jayne Meadows; that appearance marked her final acting role for 16 years. She had been signed to a contract at a major studio and studied with noted choreographers and a famed mime early in her training. On screen, her TV siblings included the characters Betty "Princess" Anderson and James "Bud" Anderson Jr., with the family matriarch and patriarch played by established performers.

Personal struggles, recovery and later work

Chapin publicly described a difficult private life: she said her mother was an alcoholic and that her father molested her, that she attempted suicide as a child and identified as having a manic depressive personality. She dropped out of Pasadena High School as a junior, said she married at 16 and divorced at 18, and later had a marriage annulled after discovering the man was still married. She said another partner turned her into a call girl and introduced her to heroin, a life she said she lived for seven years until age 25, during which she endured eight miscarriages. She sued her mother to claim a portion of the money she had earned from the show. Chapin became sober in 1970, later worked as a minister and a talent manager, and published a memoir titled Father Does Know Best in 1989. She also spoke publicly in 1989 about the contrast between the protected TV character and her own hardships.

What's easy to miss is how thoroughly Chapin's public comeback — sobriety, ministry and management work — was framed by the very visible role that first made her a household face.

Here’s the part that matters for people following this story: Chapin’s life narrative is inseparable from the show that made her famous, and her death refocuses attention on both the era of early TV and the costs faced by many child performers.
