In many of her accounts of her marriage, the grieving widow in her early 30s appears to bear little resemblance to the woman who married Aristotle Onassis, the Greek shipping magnate, four years later, or who, after his death, embarked upon a career as a book editor in New York and later told a friend she had come to realize she could not expect to live primarily through a husband. Doris Kearns Goodwin, the historian and wife of Richard Goodwin, a Kennedy aide, said in an interview on Friday, “It’s certainly not the Jackie that we knew later on.”
But, she added, “By then, she’s a different woman.”
Mrs. Kennedy might have been intentionally projecting the image expected of women at the time. She also knew that she was speaking for the historical record, since the conversations were part of a larger oral history of the Kennedy presidency. But her self-confidence seems to have grown in the White House. For the first time, she became one of her husband’s most visible assets. Her televised tour of the White House restoration that she had initiated was watched by 56 million viewers.
