J.K. Rowling

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.
