Gloria Katz, the famed Hollywood screenwriter, has died at the age of 76.

Katz passed away Sunday in Los Angeles following a long battle with ovarian cancer, according to reports.

The day of her death fell on her 49th wedding anniversary to husband Willard Miller Huyck, Jr. Together, the couple wrote a series of scripts but most notable the 1973 film, American Graffiti, which was nominated for an Academy Award. George Lucas wanted her husband “to write about cruising for American Graffiti, and I sort of came with the package,” she once said in and interview.

Katz and Huyck are famed for her work alongside Lucas and wrote the scripts for the first Star Wars film in 1977. On top of that, Katz wrote a string of scripts for the likes of Steven Spielberg’s Indiana Jones and the Temple of Doom, her husband’s film Howard the Duck and more.

When discussing the star Wars script she sent back to Lucas, Katz explained that he had “a lot of reservations” about his script for his follow-up, Star Wars. “He said, ‘Polish it — write anything you want and then I’ll go over it and see what I need,'” she added. “George didn’t want anyone to know we worked on the script, so we were in a cone of silence.”

Katz is survived by her daughter, Rebecca.
