Sir Peter Shaffer, in full Sir Peter Levin Shaffer (born May 15, 1926, London, Eng.), British playwright of considerable range who moved easily from farce to the portrayal of human anguish. Educated at St. Paul’s and Trinity College, Cambridge, Shaffer first worked for a music publisher and then as a book reviewer. His first play, Five-Finger Exercise (1960), is a tautly constructed domestic drama that almost overnight established his reputation as a playwright. It was followed by The Private Ear, The Public Eye (both 1962), and The Royal Hunt of the Sun (1964), a portrayal of the conflict between the Spanish and the Inca—“hope and hopelessness, faithlessness and faith.” In 1965 Shaffer’s adroit farce Black Comedy was performed. Equus (1973; filmed 1977), dealing with a mentally disturbed stableboy’s obsession with horses, and Amadeus (1979; filmed 1984), about the rivalry between Mozart and his fellow composer Antonio Salieri, were successes with both critics and the public. Later plays include the biblical epic Yonadab (1985), Lettice and Lovage (1987), and The Gift of the Gorgon (1992). Shaffer was knighted in 2001 and sadly passed away in 2016.
