A.A..MILNE
Alan Alexander Milne was born in London on January 18th,1882. His father was the headmaster of a small preparatory school.Milne went to Westminster School at the age of 11 and then went on to Cambridge to become a mathematician.But he became editor of the university's journal " Granta" in witch he published some of his light humorous poems.Then he went to London.By and by London magazines began to publish his witty works,and in 1905 he published his first book ,a shilling paper-back collection of humorous essays.Aged only 24 he was given a post of assistant editor of the famous magazine "Punch" , at the salary of 5 pounds a week.In 1913 he married Dorothy De Selincourt. The Milnes' only child was born on August 21st,1920. Mrs. Milne presented her husband with a lovely ,fair-haired and adorable son,Christopher Robin.The Milnes bought him teddy bear for his first birthday.The teddy bear was soon named Winnie, after a real-life bear that lived at London Zoo.A.A.Milne wrote a lot of poems for Christopher Robin and about him.Some of the poems became very popular songs.In 1925 the Milnes bought a farm in Sussex, it was ne'er into the Ashdown Forest where Chistopher Robin and his teddy,now known by the name of "Winnie-the-Pooh" or "Pooh-bear",used to play.Each daily adventure in the Forest gave A.A.Milne more material for his now famous book "Winnie-the-Pooh" published in 1926.A.A.Milne's secret for success was that he could get inside the mind of a child.He used his story-telling talents to describe how one little boy so loved his teddy bear that the toy animal came alive.The four Pooh books are still as popular today as they were many years ago.Christopher Milne spent six years in the Army during the war.Then he ran a bookshop in Dartmouth until he retired to live in the countryside.
