Littlefeather passed away Sunday in the Northern California city of Novato after a years-long battle with breast cancer that had metastasized in recent years, according to The Hollywood Reporter.
It’s been nearly 50 years since Littlefeather — then 26 — took the stage in place of Marlon Brando, who won the Best Actor Oscar for “The Godfather”, and delivered a message on Brando’s behalf about the mistreatment and oppression of Native Americans.
On Sunday, The Academy of Motion Picture Arts and Sciences announced her passing, tweeting, “Sacheen Littlefeather, Native American civil rights activist who famously declined Marlon Brando’s 1973 Best Actor Academy Award, dies at 75.”
