Joanne Rowling (/ˈroʊlɪŋ/ ROH-ling; born 31 July 1965), known by her pen name J. K. Rowling, is a British author and philanthropist. She is the author of Harry Potter, a seven-volume fantasy novel series published from 1997 to 2007. The series has sold over 600 million copies, been translated into 84 languages, and spawned a global media franchise including films and video games. The Casual Vacancy (2012) was her first novel for adults. She writes Cormoran Strike, an ongoing crime fiction series, under the alias Robert Galbraith.
Born in Yate, Gloucestershire, Rowling was working as a researcher and bilingual secretary for Amnesty International in 1990 when she conceived the idea for the Harry Potter series. The seven-year period that followed saw the death of her mother, the birth of her first child, divorce from her first husband, and relative poverty until the first novel in the series, Harry Potter and the Philosopher's Stone, was published in 1997. Six sequels followed, concluding with Harry Potter and the Deathly Hallows (2007). By 2008, Forbes had named her the world's highest-paid author.
