Anna Marie "Patty" Duke (December 14, 1946 – March 29, 2016) was an American actress of stage, film, and television.
Born Anna Marie Duke on 14 December 1946, she was one of
three children and had a difficult childhood, with her mother
putting two
talent agents in charge of her care when she was just 8 years old. She quickly
found success working in both film and television before getting her big break
at the age of 13 when she originated the role of Keller on Broadway opposite
Anne Bancroft, who played Keller's teacher Annie Sullivan.

The play ran for two years before being made into a film, in which Bancroft starred and also received an Academy Award. Duke became the youngest actor to ever receive an Oscar when she picked up the award for Best Supporting Actress.

In the show, which ran for 104 episodes from 1963 to 1966, Duke did double duty as two identical but very different cousins, one American and the other English. She was the youngest actor to have a TV series bearing her name.
While most people think of her as an actor, she also had
a recording career that began in 1965 with a top 10 hit on the Billboard Hot
100: "Don't Just Stand There" peaked at No. 8 in August of that year.
The single was released just as the second season of The Patty Duke Show was
signing off for the summer. Signed to
the United
Artists label, Duke recorded several albums, but only one appeared
on the Billboard 200.

Duke originated the role of Keller in The Miracle Worker
onstage in her Broadway debut, before making the film adaptation. For the part,
Duke is said to have rehearsed with a blindfold for roughly a year. She
revisited the material in 1979 for a TV version of the play, for which she won
an Emmy playing Keller’s teacher – the role originally played on Broadway by
Anne Bancroft.
In 1982, the actor was diagnosed with bipolar disorder.
Soon after, she became an advocate for mental health issues, working
extensively with the National Institute of Mental Health and the
National
Alliance on Mental Illness.

She documented her struggle in her 1987 autobiography,
Call Me Anna: The Autobiography of Patty Duke. In the book, Duke also alleged
that her managers, when she was a child star, had sexually abused her and
squandered her earnings. As a result, she said, she began drinking and abusing
prescription drugs as a teenager.
Over the course of her life, she was married four times
and raised three sons, two of whom – Sean and Mackenzie Astin – also became
actors.
Duke remained active in TV throughout the 1990s and
2000s. She appeared in a slew of TV movies and toplined several short-lived
series including ABC’s 1985 effort “Hail to the Chief,” in which she played the
first female president; “Karen’s Song,” an early Fox network series in 1987;
and NBC’s “Amazing Grace,” which aired in 1995. Her recent TV appearances
included guest shots on “Glee,” “Drop Dead Diva,” “Hawaii 5-0” and “Liv and
Maddie.” On August 17, 2004, Duke received a star on the Hollywood Walk of Fame
for her contributions to the motion picture industry.
She died on the morning of March 29, 2016 in Coeur d'Alene, Idaho of sepsis from a
ruptured intestine at the age of 69.
