J.K. ROWLING

Joanne Rowling (whose pen name is J.K. Rowling) is an English author from the 1990s to the present. She is best known as the author of the wildly popular Harry Potter series of books, including: Harry Potter and the Philosopher's Stone (released in the U.S. as "Harry Potter and the Sorcerer's Stone"), Harry Potter and the Chamber of Secrets, Harry Potter and the Prisoner of Azkaban, Harry Potter and the Goblet of Fire, Harry Potter and the Order of the Phoenix, Harry Potter and the Half Blood Prince, and Harry Potter and the Deathly Hallows, all of which have subsequently been turned into movie adaptations! She was the world's first billionaire author, but lost her billionaire status after giving away much of her earnings to charity (she does still remain as one of the wealthiest people in the world!).
