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.
He was born in Kilburn, London, and attended 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.
He married Dorothy "Daphne" de Sélincourt in 1913, and their only son, Christopher Robin Milne, was born in 1920. In 1925, A. A. Milne bought a country home, Cotchford Farm, in Hartfield, East Sussex. During World War II, A. A. Milne was Captain of the Home Guard in Hartfield & Forest Row, insisting on being plain 'Mr. Milne' to the members of his platoon. He retired to the farm after a stroke and brain surgery in 1952 left him an invalid and by August 1953 "he seemed very old and disenchanted".
He was 74 years old when he passed away in 1956.
