Barbara Taylor Bradford, best-selling novelist known for "A Woman of Substance," dies at 91

Barbara Taylor Bradford, a British journalist who became a publishing sensation in her 40s with the saga "A Woman of Substance" and wrote more than a dozen other novels that sold tens of millions of copies, has died. She was 91.

Bradford died Sunday at her home in New York City, a spokesperson said Monday. An obituary was also posted to her website.

Starting with "A Woman of Substance," published in 1979, Bradford averaged nearly a book a year as one of the world's most popular and wealthiest writers, her net worth estimated at more than $200 million and her fame so high that her image appeared on a postage stamp in 1999. In 2007, Queen Elizabeth II awarded her an OBE (The Most Excellent Order of the British Empire).
