She portrayed lookalike cousins on the sitcom The Patty Duke Show, was  known for Valley of the Dolls, and played leading roles in the musicals Oklahoma! and Wicked. Duke was also an activist for bipolar disorder, with which she has diagnosed in 1982. One of Duke's three children is actor Sean Astin (Lord of the Rings). Duke's family has issued the following statement, saying, "This morning, our beloved wife, mother, matriarch and the exquisite artist, humanitarian, and champion for mental health, Anna Patty Duke Pearce, closed her eyes, quieted her pain and ascended to a beautiful place. We celebrate the infinite love and compassion she shared through her work and throughout her life."
