Determined by high school to be a journalist, Ephron graduated from the single-sex Wellesley College in 1962, moved to New York and started out as a "mail girl" and fact checker at Newsweek. A newspaper strike at the end of the year gave her a chance. Victor Navasky, the future editor of The Nation, was then running a satirical magazine called the Monacle. He was working on a parody of the New York Post, "The New York Pest," and asked Ephron for a spoof of Post columnist Leonard Lyons.
She succeeded so well that the newspaper's publisher, Dorothy Schiff, reasoned that anyone who could make fun of the Post could also write for it. Ephron was asked to try out as a reporter. Within a week, she had a permanent job and remained there five years. The Post, she later wrote, was a "terrible paper," and she envied her peers at The New York Times and elsewhere who had more time to work on stories and had better access to people they wanted to interview.
"But the point is this. I was better off ..." she wrote in the introduction to the essay collection "Wallflower at the Orgy, published in 1970. "I learned to go through the clips, find the names of people from the subject's past, hunt them up in old telephone books, track them down, and pull out anecdotes they knew. What I'm saying may seem obvious; but one of the things that stuns me is how seldom reporters do this."
Ephron began writing for Esquire and The New York Times and developed a national following as a throwback to the prime of Dorothy Parker and S.J. Perelman and a worthy peer of such new and hip journalists as Gay Talese and Tom Wolfe. She covered political conventions, the feminist movement and Wellesley, which she labeled a factory for "docile" women. Part of her gift was her fresh takes on such traditional subjects for women as food and fashion, like in the essay "The Food Establishment: Life in the Land of the Rising Souffle (Or Is It the Rising Meringue?)"
"The typical member of the Food Establishment," she wrote, "is given to telling you, apropos of nothing, how many souffles he has been known to make in a short period of time. ... He gossips a good deal about his colleagues, about what they are cooking, writing, and eating; and whom they are talking to, about everything, in fact, except the one thing everyone else in the universe gossips about — who is sleeping with whom."
By the 1970s, she had met Bernstein, who teamed with fellow Washington Post reporter Bob Woodward on prize-winning coverage of the Watergate scandal that brought down President Nixon. They married in 1976, and had two children, but love soon turned to hate — and matured into art. Ephron was pregnant with their second child when she learned Bernstein was having an affair, a betrayal that had its rewards, once she stopped crying.
She wrote "Heartburn," later a film starring Streep and Jack Nicholson and directed by Nichols, with whom she collaborated often. The book was so close to her life that Bernstein threatened to sue. Decades later, the memory of the book's birth was easily summoned.
"Yes, totally, completely, absolutely, sitting at the legendary and long-gone Smith Corona electric typewriter that I once had," she told The Associated Press in 2010. "I was working on a screenplay and wrote the first 10 pages of a novel, and I knew the title, knew there were going to be recipes in it. This I remember, exactly where I was, working and knowing, 'Oh, I see, enough time has passed that I'm ready to do this.'"
Another perk from her time with Bernstein: She sussed out that "Deep Throat," the unnamed and unknown Watergate source, was in fact FBI official Mark Felt. She would allege that she told countless people about Felt, who did not acknowledge his role until years later.
Her screenwriting credits included "Heartburn," the nuclear power drama "Silkwood" and the romantic comedy "When Harry Met Sally ..." She twice directed the team of Ryan and Hanks, in "Sleepless in Seattle" and "You've Got Mail," and also worked with John Travolta (in the fantasy "Michael"), Steve Martin ("Mixed Nuts") and Nicole Kidman ("Bewitched").
