J.K. Rowling is a British author, screenwriter and film producer, best known for writing the Harry Potter book series. The books gained worldwide popularity, receiving multiple awards and selling over 600 million copies, making it the best-selling literary series in history. Warner Bros. adapted the books for the film industry, achieving great success.

Rowling has also written several books for an adult audience: Sudden Death (2012), and The Cuckoo’s Calling (2013), under the pseudonym Robert Galbraith, one among others in the Cormoran Strike series of crime fiction.
Born in Yate, England, Rowling had the idea to write the series while on a train going from Manchester to London in 1990. Over a period of seven years, Rowling experienced the death of her mother, the birth of her first daughter, her divorce from her first husband and a personal financial crisis.
She finished the first of the seven books in the Harry Potter series, Harry Potter and the Philosopher’s Stone, in 1997 and the last one, Harry Potter and the Deathly Hallows, in 2007.
After the success of Harry Potter, Rowling bounced back financially and went from poverty to multimillion-dollar wealth in five years. She is the best-selling British author, with over £238 million in book sales.
