Duke met with the real life Helen Keller in 1961. The actress was just 15 at the time. In the photo, Duke is seen kneeling down next to Keller and grasping her hand.
The two sat down together before Duke went on to portray Keller in the film adaption of the play.

In the film, Duke played a young Keller, who was struggling to communicate after being left deaf and blind following a fever as a baby. As a last resort before institutionalizing Keller for her violent outbreaks, her parents hired half-blind Annie Sullivan.
Duke died on Tuesday, after a battle with sepsis that was a result of a ruptured intestine.
Duke’s son Sean Astin has said that his mother was “at peace” when she died.
