Peter Sydney Ernest Lawford (born Peter Sydney Ernest Aylen; 7 September 1923 – 24 December 1984) was an English-born American actor.
He was a member of the "Rat Pack" and brother-in-law to President John F. Kennedy, and more noted in later years for his off-screen activities as a celebrity than for his acting. From the 1940s to the 1960s, he had a strong presence in popular culture and starred in a number of highly acclaimed films.
