The one-time single mom on welfare is the brains behind Harry Potter, one of the most successful book franchises in history. The sixth installment, Harry Potter and the Half-Blood Prince, was the fastest-selling book in history, according to Guiness World Records. The film series--from which Rowling enjoys a cut of royalties and merchandising--has also proven astoundingly successful, with the total gross for the four films already released topping $3.5 billion. Rowling is the only career author on Forbes' Billionaires list.
