Audrey Kathleen Ruston Hepburn

In 1952, Hepburn was engaged to the young James Hanson, whom she had known since her London dancing days. She called it "love at first sight"; however, after having her wedding dress fitted and the date set, she decided the marriage would not work because the demands of their careers would keep them apart most of the time. She issued a statement about her decision, saying, "When I get married, I want to be really married." In the early 1950s, she also dated future Hair producer Michael Butler.
Hepburn and Gregory Peck bonded during the filming of Roman Holiday (1953) and there were rumours that they were romantically involved; both denied it. Hepburn, however, added, "Actually, you have to be a little bit in love with your leading man and vice versa. If you're going to portray love, you have to feel it. You can't do it any other way. But you don't carry it beyond the set." They did however become lifelong friends. During the filming of Sabrina (1954), Hepburn and the already-married William Holden became romantically involved. She hoped to marry him and have children, but she broke off the relationship when Holden revealed that he had undergone a vasectomy. Although a common perception that Bogart and Hepburn (both starred in Sabrina together) did not get along, Hepburn commented that, "Sometimes it's the so-called 'tough guys' that are the most tender hearted, as Bogey was with me."
At a cocktail party hosted by Gregory Peck, Hepburn met American actor Mel Ferrer. Ferrer recalled that, "We began talking about theatre; she knew all about the La Jolla Playhouse Summer Theatre, where Greg Peck and I had been co-producing plays. She also said she'd seen me three times in the movie Lili. Finally, she said she'd like to do a play with me, and she asked me to send her a likely play if I found one." Ferrer, vying for Hepburn to take the title role, sent her the script for the play Ondine. She agreed and rehearsals started in January 1954. Eight months later, on 25 September 1954, after meeting, working together, and falling in love, the pair were married in Bürgenstock while preparing to star together in the film War and Peace (1955).
Before having their only son, Hepburn had two miscarriages in March 1955 and in 1959. The latter occurred when filming The Unforgiven (1960) where breaking her back after falling off a horse and onto a rock resulted in hospital stay and miscarriage induced by physical and mental stress. Hepburn took a year off work in order to carry a child to term. Sean Hepburn Ferrer, their son, whose godfather was the novelist A. J. Cronin, who resided near Hepburn in Lucerne, was born on 17 July 1960.
