Sir Terence Mervyn Rattigan (10 June 1911 – 30 November 1977) was a British dramatist and screenwriter. He was one of England's most popular mid-20th-century dramatists. His plays are typically set in an upper-middle-class background. He wrote The Winslow Boy (1946), The Browning Version (1948), The Deep Blue Sea (1952) and Separate Tables (1954), among many others.
A troubled gay man who saw himself as an outsider, Rattigan wrote a number of plays which centred on issues of sexual frustration, failed relationships, or a world of repression and reticence.
