Katherine Boyer Waterston is a British-American actress renowned for her versatile performances across film, television, and theater.
Born on March 3, 1980, in Westminster, London, she holds dual citizenship in the United Kingdom and the United States.
Her parents are American: her father, Sam Waterston, is an acclaimed actor best known for his long-running role as Jack McCoy on the television series Law & Order, and her mother, Lynn Louisa Woodruff, is a former fashion model.
Although born in London due to her parents’ work commitments at the time, Katherine was primarily raised in Connecticut, where she grew up in an artistic household that frequently exposed her to film and television sets through her father’s career.
She attended the Loomis Chaffee School, graduating in 1998, before pursuing formal training at New York University’s Tisch School of the Arts, where she earned a Bachelor of Fine Arts in acting.
Despite initially considering a double major in theater and photography, she focused solely on acting to fully develop her skills.
Siblings
Katherine’s older sister, Elisabeth Waterston, born in 1977, is an actress who has appeared in numerous television shows and films, including roles in Boardwalk Empire and the 2003 film The Rules of Attraction.
Elisabeth has built a steady career in both stage and screen work, often collaborating within the family circle.
Katherine’s younger brother, Graham Waterston, born in 1983, works primarily behind the camera as a director, producer, writer, and crew member on various television and film projects, choosing a less spotlight-focused role compared to his sisters.
Additionally, Katherine has an older half-brother, James Waterston, born in 1969 from her father’s first marriage to Barbara Rutledge Johns, which ended in 1975.
James is also an actor, gaining early recognition for his role as Gerard Pitts in the 1989 film Dead Poets Society and appearing in television series such as The Good Wife and The Blacklist.
