Among his long list of accolades, Poitier became the first African American actor to be nominated for an Academy Award for best actor (for "The Defiant Ones" in 1958) and six years later became the first Black man to win an Academy Award, this time for "Lilies of the Field."
Poitier was honored many times while he was alive: The American Film Institute included him on its 1999 list of greatest male Hollywood stars, Queen Elizabeth II knighted him in 1974 and President Barack Obama awarded him the Presidential Medal of Freedom in 2009.
After his death many stars are continuing their praise by remembering and paying homage to the "landmark actor" and "man among men." In a statement Friday, President Joe Biden honored Poitier as a "once-in-a-generation actor and advocate whose work carried so much dignity, power, and grace that it changed the world on and off the big screen."
"With unflinching grandeur and poise — his singular warmth, depth, and stature on-screen — Sidney helped open the hearts of millions and changed the way America saw itself," the president added. "He blazed a path for our Nation to follow, and a legacy that touches every part of our society today."
Biden continued: "Jill and I send our love and prayers to Sidney’s wife, Joanna, his daughters, and his grandchildren and great-grandchildren. May God bless Sidney Poitier."
Denzel Washington remembered Poitier as a friend who helped set the stage for him and many others.
"It was a privilege to call Sidney Poitier my friend. He was a gentle man and opened doors for all of us that had been closed for years," Washington said in a statement to USA TODAY Friday. "God bless him and his family."
Oprah Winfrey posted a touching photo of her and Portier embracing one another while smiling on Instagram.
"For me, the greatest of the 'Great Trees' has fallen: Sidney Poitier," Winfrey wrote. "My honor to have loved him as a mentor. Friend. Brother. Confidant. Wisdom teacher. The utmost, highest regard and praise for his most magnificent, gracious, eloquent life."
"The dignity, normalcy, strength, excellence and sheer electricity you brought to your roles showed us that we, as Black folks, mattered," Davis wrote. "You told us,'If your dreams do not scare you, they're not big enough!' I put this quote on my daughter's wall. Rest well Mr. Poitier. Thank you! Thank you for leaving a legacy. May flights of angels sing thee to thy rest."
"To wake up this morning to a call that Sidney Poitier has passed away... all I can tell you is that my heart broke in another place. The grace and class that this man has shown throughout his entire life, the example he set for me, not only as a black man but as a human being will never be forgotten," Perry wrote.
Around this time last year Cicely Tyson was releasing her book and promoting it. I had no idea she would pass away shortly thereafter. Now, to wake up this morning to a call that Sidney Poitier has passed away... continued: https://t.co/WWbsTgh1U0pic.twitter.com/jgezv2ktGD
The 52-year-old screenwriter, actor and producer added details a "life changing" memory of him spending time with both Poitier and the late actress Cicely Tyson.
"I’ll never forget inviting him and Cicely to fly to South Africa with me. Selfishly, I wanted to hold them both captive for the hours long trip as I literally sat at their feet and listened to their wisdom and experiences," he wrote. "All I can say is thank you for your life, thank you for your example, and thank you for your incredible gift. But most of all, thank you for being willing to share YOU to make us all better."
Former President Barack Obama shared a photo of him, Michelle Obama and Portier in the White House.
"Through his groundbreaking roles and singular talent, Sidney Poitier epitomized dignity and grace, revealing the power of movies to bring us closer together. He also opened doors for a generation of actors," Obama wrote. "Michelle and I send our love to his family and legion of fans."
Don Cheadle said Friday he was "gutted" by Poitier's death.
"Lost another royal. Sir Poitier had no peer, and we’ll never see his like again. He was the standard bearer for generations of actors/directors who came after him," Cheadle said in a statement to USA TODAY Friday, recalling the last time he saw Poitier "was at a golf course in L.A. I saw him across the room and walked toward him with my hand out to shake his. Ignoring my hand, he opened both of his arms wide and embraced me warmly.
"Then he let me go and held me at arm’s length staring me in my eyes and said in his signature cadence, 'I dig what you do, my man.' I almost fainted. He told me to keep it up and keep representing us. I told him I would do my best and that he was irreplaceable. We were so blessed to have him for as long as we did, and he will be sorely and surely missed."
Director Kenny Leon, who won a Tony for his 2014 rendition of the 1959 Broadway play "A Raisin in the Sun," in which Poitier was part of the original cast, remembered Poitier by thanking "God for sharing" the actor with the world.
"Rest in dear sweet peace sir Sidney Poitier..where would we be without your sacrifices? an artist among artist-a man among men," Leon wrote.
Whoopi Goldberg tweeted lyrics for the song that accompanied Poitier's 1967 film "To Sir, with Love," adding, "Sir Sidney Poitier R.I.P. He showed us how to reach for the stars."
Dionne Warwick recalled a time meeting Poitier when she was younger, which resulted in the late actor giving her a nickname.
"He once caught me following him. He said 'little girl what do you want' I muttered 'can I have your autograph,' " Warwick wrote. "From that day he always called me little girl and asked if I wanted his autograph. It was something we laughed about. He was my hero & great friend."Jada Pinkett Smith wrote: "Trailblazing is not easy and you did it with grace and tenacity. I am grateful. Rest in Love."
"We lost an elegant King today. Thank you Sidney Poitier. For not only opening the door, but for walking in this world with endless grace and excellence, so that today, still, we follow behind you, reaching toward the example that you set," Kerry Washington wrote.

George Takei remembered Poitier as a "trailblazer who will be mourned by so many for whom he opened the very doors of Hollywood."
Sidney Poitier, the first Black man to win an Oscar, has died at the age of 94. The star of “Guess Who’s Coming To Dinner” and “Lilies of the Field,” for which he won Best Actor, was a trailblazer who will be mourned by so many for whom he opened the very doors of Hollywood.
"Candyman" actor Colman Domingo wrote: "Until I can properly eulogize him later. Heart broken. I am because of him. He blazed a tremendous path for thespians such as me. I am forever grateful. Standing O for this giant."
Poitier's acting career began with the American Negro Theater and five years later, he was starring in his first feature film: "No Way Out," a hospital drama about a doctor (Poitier) confronted with racism by a white patient he is working to save. He went on to star in films such as "To Sir, with Love" and "In the Heat of the Night." Over the years, he built up a reputation for playing gentle, kind and smart characters.
