Peter Lawford
Peter Sydney Ernest Lawford (né Aylen; 7 September 1923 – 24 December 1984) was an English-American actor. He was a member of the "Rat Pack" and the brother-in-law of U.S. president John F. Kennedy and senators Robert F. Kennedy and Edward Kennedy. From the 1940s to the 1960s, he was a well-known celebrity and starred in a number of highly acclaimed films. In later years, he was noted more for his off-screen activities as a celebrity than for his acting; it was said that he became "famous for being famous".
