Oscar and Emmy-winning actress Patty Duke has died at the age of 69, TheWrap has learned.
The cause of death was sepsis from a ruptured intestine.
"She was a wife, a mother, a grandmother, a friend, a mental health advocate and a cultural icon. She will be greatly missed," said her manager in a statement.
Duke started her career as a child actress on daytime soap opera "The Brighter Day," and she won an Oscar for Best Supporting Actress for "The Miracle Worker" when she was just 16, becoming the youngest Oscar winner at the time.
