The Academy of Motion Picture Arts and Sciences has apologised to Sacheen Littlefeather.
She is a Native-American activist who endured abuse when she took a stand in the 1970s against anti-Indigenous racism in the United States film industry.
The US film academy said in a statement on Monday that it will host Littlefeather, now 75, for an evening of conversation and healing on September 17.
Littlefeather received a formal letter of apology from the head of the academy in June.
It was nearly 50 years after taking the stage at the 1973 Oscar awards ceremony.
She became the target of racist abuse after she announced that actor Marlon Brando would not accept an award for his performance in “The Godfather” in protest of the poor treatment that Native Americans received in the film industry.
