Patty Duke

Anna Marie Duke (December 14, 1946 - March 29, 2016), known professionally as Patty Duke, was an American actress. Beginning her acting career in commercials and playing bit parts in television and movies, her breakthrough role was as Helen Keller in the Broadway version of "The Miracle Worker" (1959 - 1961). For the 1962 film adaptation, Duke reprised her role, which won the Academy Award for best supporting actress - at age 16, she was the youngest person ever to win an Oscar (a record later broken by Tatum O'Neal in 1973).
