Every week she was billed above the then-young John Travolta as one of the co-stars of the 1970s hit “Welcome Back, Kotter.”

Actress Marcia Strassman, 66, who played Gabriel Kaplan’s wife, Julie, on the show, has died, reports the Associated Press.

Strassman died on Friday at her Sherman Oaks, Calif., home after a seven-year battle with breast cancer, her sister said. Doctors had given her two-and-a-half years, but “she lasted much longer,” her sister, Julie Strassman, said. “She was very courageous.”

The actress portrayed nurse Margie Cutler on the first season of “MASH” before she joined “Kotter.” In the Disney movie “Honey I Shrunk the Kids” and its sequel, “Honey I Blew Up the Kid,” she played Rick Moranis’ wife.

Strassman was a member of the Screen Actors Guild national board and was involved in social causes such as fundraising for breast cancer research, her sister said.
