Poitier became the first Black man to win the Academy Award for best actor in 1963, rising to the top of his career and blazing a trail for Black artists who followed.

Since his death earlier this month, Poitier has been celebrated by fellow performers and for his contributions on screen and remembered by friends and family for his graciousness, advocacy work and goodness off screen.

“We know how graceful and wise he was. How powerful his strength of character and moral fortitude. But what I really want people to know is how GOOD he was,” his daughter, Sydney Poitier wrote in a powerful tribute on Instagram last week.

“I know people know he was good, but I don’t think they know the depth of his goodness. That it permeated every cell of his being,” she wrote. “It’s his goodness that changed the world, and it will live on forever.”
