Joanne "Jo" Murray (née Rowling; born 31 July 1965), better known under the pen name J. K. Rowling (pronounced /ˈroʊlɪŋ/, ROE-ling), is a British author best known as the creator of the Harry Potter fantasy series, the idea for which was conceived whilst on a train trip from Manchester to London in 1990. The Potter books have gained worldwide attention, won multiple awards, sold more than 400 million copies, and been the basis for a popular series of films. Aside from writing the Potter novels, Rowling is perhaps equally famous for her "rags to riches" life story, in which she progressed from living on welfare to multi-millionaire status within five years. The 2008 Sunday Times Rich List estimated Rowling's fortune at £560 million ($798 million), ranking her as the twelfth richest woman in Britain. Forbes ranked Rowling as the forty-eighth most powerful celebrity of 2007, and Time magazine named her as a runner-up for its 2007 Person of the Year, noting the social, moral, and political inspiration she has given her fandom. She has become a notable philanthropist, supporting such charities as Comic Relief, One Parent Families, Multiple Sclerosis Society of Great Britain, and the Children's High Level Group.
