Alan Alexander Milne ( /ˈmɪln/) (18 January 1882 –31 January 1956) was an English author, best known for his books about the teddy bear Winnie-the-Pooh and for various children's poems. Milne was a noted writer, primarily as a playwright, before the huge success of Pooh overshadowed all his previous work. Milne was almost always credited as A. A. Milne.
A. A. Milne was born in Kilburn, London, to parents John Vine Milne and Sarah Maria (née Heginbotham) and grew up at Henley House School, 6/7 Mortimer Road (now Crescent), Kilburn, a small public 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. While there, 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.
Milne joined the British Army in World War I and served as an officer in the Royal Warwickshire Regiment and later, after a debilitating illness, the Royal Corps of Signals. He was discharged on February 14, 1919.
