Alan Alexander Milne was born in Kilburn, London to parents John Vine Milne, who was born in England, and Sarah Marie Milne (née Heginbotham). He grew up at Henley House School, 6/7 Mortimer Road (now Crescent), Kilburn, a small independent school run by his father. One of his teachers was H. G. Wells, who taught there in 1889–90. Milne attended Westminster School and Trinity College, Cambridge where he studied on a mathematics scholarship, graduating with a B.A. in Mathematics in 1903. He edited and wrote for "Granta", a student magazine. He collaborated with his brother Kenneth and their articles appeared over the initials AKM. Milne's work came to the attention of the leading British humour magazine "Punch", where Milne was to become a contributor and later an assistant editor. Considered a talented cricket fielder, Milne played for two amateur teams that were largely composed of British writers: the Allahakbarries and the Authors XI. His teammates included fellow writers J. M. Barrie, Arthur Conan Doyle and P. G. Wodehouse.
