William Babington Maxwell (1866–1938) was a British novelist. Born on June 4, 1866, he was the third surviving child and second eldest son of novelist Mary Elizabeth Braddon. Though nearly 50 years old at the outbreak of the First World War, he was accepted as a lieutenant in the Royal Fusiliers and served in France until 1917. He wrote The Last Man In, a drama, produced 14 March 1910, at the Royalty Theatre, Glasgow, by the Scottish Repertory Company; and, with George Paston (i. e., Emily Morse Symonds), a farce, The Naked Truth, which was first played at Wyndham's Theatre, London, in April, 1910, and in which Charles Hawtrey played Bernard Darrell.
