Pat Hitchcock, the daughter of the legendary director Alfred Hitchcock, passed away on Tuesday at her home in Thousand Oaks, California. She was 93 years-old.

Born in 1928 as the only child of Alfred and his infamously loyal wife, Alma Reville, Pat would appear in various films directed by her father, including 1950’s Stage Fright and the 1951 classic Strangers on a Train. Audiences today, however, would likely best remember Pat for her role in 1960’s Psycho, when she gave Janet Leigh’s wound-tight character a tranquilizer.

“I would have loved it if he had believed in nepotism so that I could have done more pictures with him, but he only cast people if he thought they were absolutely right for the part,” Pat later said of her father, according to Yahoo News.

“He never fit a story to a star or to an actor. Often I tried to hint to his assistant, but I never got very far,” she added. “She’d bring my name up, he’d say, ‘She isn’t right for it,’ and that would be the end of that.”

Through the years, Pat often credited her mother for her father’s success in films.

“My mother was the one who really was in on everything from the very beginning. When he would find a story that he was anxious to do, he would have her read it,” Pat said in the documentary “The Making Of Psycho‘ in 1997, according to Page Six.

“If she didn’t think it would make a picture, he didn’t touch it,” she added. “Then she would be the first one to read the treatment and the screenplay, and she was even in on a lot of the casting, too. When she died, Charles Champlin of the Los Angeles Times said: ‘The Hitchcock touch had four hands, and two of them were Alma’s.’”

Throughout the 1950s, Pat appeared in nearly a dozen episodes of “Alfred Hitchcock Presents.” She also had roles on Broadway and in “Playhouse 90,” as well as many other classic 1950s television shows.

Pat married Joseph E. O’Connell, Jr., in 1952, and she mostly retired from acting to raise their three daughters, Mary Alma Stone, Teresa “Tere” Carrubba and Kathleen “Katie” Fiala. O’Connell died in 1994, but their three daughters survive Pat.
