Lauren Ann Chapin (May 23, 1945 â February 24, 2026) was a five time Jr. Emmy award winning American actress who played the role of the youngest child "Kathy Anderson" (nicknamed "Kitten") on the television show Father Knows Best between 1954 and 1960. She appeared in 196 episodes of the 203 in the series. Two of her older brothers were also child stars, Billy and Michael Chapin.
Chapin was born in Los Angeles to a banker father, William Chapin, and a mother, Marguerite (Barringer) Chapin, who was a classically trained pianist.
Chapin made her first TV appearance on the show "Lux Video Theater" in 1952. Two years later, she auditioned for "Father Knows Best" and won the part -- she felt she beat out other girls because she resembled one of the real-life daughters of the show's star, Robert Young.
Chapin also had roles in A Star Is Born (1954), The Bob Hope Show (1954), The Ed Sullivan Show (1958), The Amorous Adventures of Don Quixote and Sancho Panza (1976), Scout's Honor (1980), the 36th Primetime Emmy Awards (1984), and School Bus Diaries (2016). She also appeared in two "Father Knows Best" reunions in 1977.
Chapin also taught natural childbirth and worked for a brokerage firm. She later owned two beauty pageant enterprises. She also was a licensed and ordained evangelist and advocate for Israel.
In 1989, Chapin wrote a well-received autobiography, Father Does Know Best: The Lauren Chapin Story.
In 1999, Chapin was the subject of the documentary "Lauren Chapin: The E! True Hollywood Story."
In the late 1980s while living in Texas with her son and daughter, Chapin managed actress Jennifer Love Hewitt, who was a friend of her daughter, Summer Healy Chapin. Chapin brought both girls to Los Angeles, where they were signed by an agency. Chapin had second thoughts and withdrew her daughter. However, that move launched Hewitt's career.
Chapin died from cancer in Miami, Florida, on February 24, 2026, at the age of 80.
