Alan Alexander Milne 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 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 recruited into Military Intelligence to write propaganda articles for MI 7b between 1916 and 1918. He was discharged on 14 February 1919, and settled in Mallord Street, Chelsea.
