Angela Margaret Cartwright was born September 9, 1952, in Altrincham, Cheshire, England, but Hollywood claimed her early. Her family relocated to Los Angeles when she was barely a year old, and by three she was already sharing scenes with Paul Newman in Somebody Up There Likes Me and appearing with Rock Hudson and Sidney Poitier in Something of Value. From the beginning she had a calm, luminous presence—a child actor who didn’t perform so much as inhabit the moment.
Television embraced her early. Cartwright became a familiar face in living rooms across America as Linda Williams on The Danny Thomas Show, a role she played for seven seasons. It wasn’t a flighty child-star arrangement either; she and Danny Thomas formed a bond that lasted long after the cameras shut down. Their relationship became a sort of showbiz family tie, one that continued until Thomas’ death in 1991.
Her biggest cinematic credit came with The Sound of Music, where she played Brigitta von Trapp in the 1965 blockbuster that became, for a time, the highest-grossing film ever made. Cartwright’s Brigitta was bright, impish, and observant—a perfect fit for an actress who always seemed to be quietly watching the world.
That same year she stepped into another pop-culture landmark: Lost in Space. As Penny Robinson from 1965 to 1968, Cartwright played the brainy, adventurous middle child caught in the Robinsons’ interstellar chaos. Penny became one of the series’ most beloved characters—plucky, empathetic, and grounded in a crew of eccentrics. Cartwright’s chemistry with Billy Mumy, who played Will Robinson, remains a nostalgic touchstone for fans of 1960s sci-fi.
She continued acting through the 1970s and 1980s, appearing in Beyond the Poseidon Adventure, My Three Sons, Adam-12, The Love Boat, Scout’s Honor, and High School U.S.A. Later she paid affectionate tribute to her sci-fi roots with cameo appearances in both the 1998 Lost in Space film and the 2018 Netflix reboot, where she played Dr. Smith’s mother.
But performance is only half of Angela Cartwright’s creative life. For more than 30 years she has cultivated a parallel career as a photographer, developing a distinctive artistic voice. Her studio in Studio City exhibits work that blends whimsy, texture, and a quietly searching sensibility—the same qualities she often brought to her acting.
Cartwright married Steve Gullion in 1976, and together they raised two children. A practicing Catholic, she has attended Mass at St. Charles Borromeo with her sister, actress Veronica Cartwright—another veteran performer with whom she shares both a childhood and a legacy in Hollywood.
Angela Cartwright’s career spans film, television, photography, and decades of pop-culture history. Yet her work remains linked by a single thread: a sense of curiosity and warmth that has never dimmed, from Brigitta and Penny to her present life behind the lens.
