Jacqueline Bouvier Rennedy OnassIis was one of the most private women in the world, yet when she went to work as an editor in the last two decades of her life, she revealed(展现) herself as she did nowhere else.
After the death of her second husband, Greek shipping magnate (巨头 ) Aristotle  Onassis, Jacqueline's close friend and former While House social secretary Letitia Baldrige made a suggestion that she consider a career(职业) in publishing. After consideration, Jacqueline accepted it. Perhaps she hoped to find there some ideas about how to live her own life .She became not less but more interested in reading. For the last 20 years of her life, Jacqueline worked as a publisher's editor, first at Viking, then at Doubleday, pursuing (迫求 ) a late-life career longer than her two marriages combined. During her time in publishing, she was responsible for managing and editing more than 100 successfully marketed books. Among the first books were in the Russian Style and Inventive Paris Clothes. She also succeeded in persuading TV hosts Bill Moyers and Joseph Campbell to transform their popular television conversations into a book, The Power of Myth. The book went on to become an international best-seller. She dealt, too, with Michael Jackson as he prepared his autobiography(自传)，Moonwalk.
Jacqueline may have been hired for her name and for her social relations , but she soon proved her worth. Her choices, suggestions and widespread social relations were of benefit both to the publishing firms and to Jacqueline herself. In the books she selected for publication, she built on a lifetime of spending time by herself as a reader and left a record of the growth of her mind. Her books are the autobiography she never wrote, Her role as First Lady, in the end, was overshadowed by her performance as an editor. However, few knew that she had achieved so much.
