Francesca Segal says her father died Sunday at his London home from a heart attack and a funeral was held Tuesday.
"Love Story," a novel about a young couple dealing with love and bereavement, was turned into a film in 1970. The movie was nominated for seven Oscars, including best writer, best picture, best director and best actor and actress. It won only for best music.
Segal was a fellow of Wolfson College at Oxford University.
He is survived by his wife, Karen James, and daughters Francesca and Miranda.
