Andrew Sullivan was born in August 1963 in a small town in Southern England, South Godstone. He attended Reigate Grammar School, and Magdalen College, Oxford, where he took a First in Modern History and Modern Languages. He was also President of the Oxford Union in his Second Year at college, and spent his summer vacations as an actor in the National Youth Theatre of Great Britain. In 1984, he won a Harkness Fellowship to Harvard's John F. Kennedy School of Government, and earned a Masters degree in Public Administration in 1986.
In 1990, he returned to Washington, D.C., where he free-lanced for the Telegraph and started a monthly column for Esquire. He was soon back at The New Republic as deputy editor under Hendrik Hertzberg, and in June of 1991 was appointed acting editor, at the age of 27.
