Joanne Rowling, also known as J.K. Rowling is the author of the Harry Potter series, one of the most successful book series ever in the history of humankind. The reason for she writing as J.K. Rowling is because her publishing company feared that teenagers wouldn´t buy books written by a woman, so they suggested she used her two initial name letters. Joanne didn´t have a second name, so she borrowed the letter K from Kathleen, her dad´s mother name.

She had the idea of writing Harry Potter when she was traveling in a train from Manchester to London. She tells she had never been so excited to write than when she had the aforementioned idea. As soon as she reached her apartment, she started writing.

Before publishing her first Harry Potter book, she moved to Oporto, Portugal to work as an English teacher in an Academy. She then married Jorge Arantes in 1992. Two years later she put a restraining order on his spouse. In 1995, the divorce was approved.
