Sir Peter Ustinov (16 April 1921 – 28 March 2004) was an English actor, writer, dramatist, filmmaker, theatre and opera director, stage designer, screenwriter, comedian, humorist, newspaper and magazine columnist, radio broadcaster, and television presenter. He was a fixture on television talk shows and lecture circuits for much of his career. A respected intellectual and diplomat, he held various academic posts and served as a Goodwill Ambassador for UNICEF and President of the World Federalist Movement.
Ustinov was the winner of numerous awards over his life, including two Academy Awards for Best Supporting Actor, Emmy Awards, Golden Globes and BAFTA Awards for acting, and a Grammy Award for best recording for children, as well as the recipient of governmental honours from, amongst others, the United Kingdom, France, and Germany. He displayed a unique cultural versatility that has frequently earned him the accolade of a Renaissance man. Miklós Rózsa, composer of the music for Quo Vadis and of numerous concert works, dedicated his String Quartet No. 1, Op. 22 (1950) to Ustinov.
