Angela Cartwright (Brigitta/Penny)
Angela Cartwright is an English-born American actress. She was Brigitta von Trapp in The Sound of Music (1965), but she was also Penny Robinson in Lost in Space (1965-1968). She appeared in episodes of My Three Sons, Adam-12, and The Love-Boat. She took on the role of Theresa Mazzetti in Beyond the Poseidon Adventure (1979).

After all that, Cartwright married Steve Gullion in 1976 and had two children. She also became a photographer, with her art on display in Studio City, California. She explained, “Photography has been a passion of mine since I was 15. After my kids were born I found myself incorporating my photography into different art endeavors and from there it just blossomed.”
Cartwright also has her own line of jewelry and clothing. As a throw-back to that long-past sitcom, she made a cameo appearance as a reporter on Lost in Space, the 1998 movie remake.
