Sir Arthur Wynne Morgan Bryant, (18 February 1899 – 22 January 1985) was an English historian, columnist for "The Illustrated London News" and man of affairs. His books included studies of Samuel Pepys, accounts of English eighteenth- and nineteenth-century history, and a life of George V. Whilst his scholarly reputation has declined somewhat since his death, he continues to be read and to be the subject of detailed historical studies. He moved in high government circles, where his works were influential, being the favourite historian of three prime ministers: Winston Churchill, Clement Attlee, and Harold Wilson.
