The Dublin-born actress received an Academy Award nomination for her performance as Isabella Linton in "Wuthering Heights" in 1939, appearing with Laurence Olivier and Merle Oberon in director William Wyler's screen version of the Emily Bronte novel.
That same year she also starred with Bette Davis, George Brent and Humphrey Bogart in the popular Hollywood tearjerker "Dark Victory."
Shirley Jones, who co-starred with Fitzgerald in the 1970s made-for-TV movie "Yesterday's Child" called Fitzgerald a consummate actress.
Fitzgerald received a Tony nomination in 1982, for directing "Mass Appeal," a play about the conflicts between an older and younger priest.
Among her New York stage appearances were roles in several Eugene O'Neill revivals, most notably as Mary Tyrone in a 1971 off-Broadway production of "Long Day's Journey into Night," which starred Robert Ryan. In 1977, she starred with Jason Robards in a revival of O'Neill's "A Touch of the Poet."
Fitzgerald's first marriage to Edward Lindsay-Hogg ended in divorce. She later married businessman Stuart Scheftel, who died in 1994. Fitzgerald is survived by a son, director Michael Lindsay-Hogg of Los Angeles, and a daughter Susan Scheftel of New York.
