After the announcement late Friday that the “Black Panther” star Chadwick Boseman had died, tributes began pouring in on social media from prominent figures in entertainment, politics and beyond.
Mr. Boseman, 43, had portrayed pathbreaking Black Americans onscreen, including Jackie Robinson, James Brown and Thurgood Marshall. He died on Friday after a yearslong battle with colon cancer.
Within minutes, Martin Luther King III, a human-rights activist and the eldest son of the Rev. Dr. Martin Luther King Jr., said that the actor had “brought history to life on the silver screen” in his portrayals of Black leaders.
“As Black Panther, he was also a superhero to many,” Mr. King wrote. “And despite his 4 year long battle with cancer, he kept fighting and he kept inspiring. He will be missed.”
Former Vice President Joseph R. Biden Jr., the Democratic nominee for president, struck a similar note, saying that Mr. Boseman’s “true power” stretched far beyond Hollywood, and that he had “inspired generations and showed them they can be anything they want — even super heroes.”
St. Jude Children’s Research Hospital recalled Mr. Boseman visited young cancer patients on the Memphis campus two years ago.
He “brought with him not only toys for our patients but also joy, courage and inspiration,” the hospital wrote on Twitter.
“He was a gentle soul and a brilliant artist, who will stay with us for eternity through his iconic performances over his short yet illustrious career,” the actor Denzel Washington, who once financed Mr. Boseman’s studies at an elite theater program at the University of Oxford, said in a statement to The Hollywood Reporter. “God bless Chadwick Boseman.”
Mr. Boseman portrayed the baseball icon Jackie Robinson in “42,” in 2013, the soul singer James Brown in “Get On Up,” in 2014, and the Supreme Court justice Thurgood Marshall in “Marshall,” in 2017.
But he was best known for his role as T’Challa, king of the fictional African nation of Wakanda, in “Black Panther,” the 2018 Marvel superhero movie.
Mr. Boseman played T’Challa in three other Marvel films, including two of the “Avengers” movies. On Friday, many of his co-stars from those films tweeted about him in personal terms.
“You were always light and love to me,” wrote Don Cheadle, who played a superhero called War Machine.
“What a man, and what an immense talent,” wrote Mark Ruffalo, who played the Hulk. “Brother, you were one of the all time greats and your greatness was only beginning.”
Marvel’s rival DC Comics, the home of Batman, Superman and Wonder Woman, praised Mr. Boseman in a tweet with a photo of the actor in his “Black Panther” role. “To a hero who transcends universes,” the company said. “Wakanda Forever.”
As the night wore on, tributes to Mr. Boseman’s talents and character came from dozens of actors, directors, musicians, politicians and other celebrities. The list included Halle Berry, Mariah Carey, Ava DuVernay, Chosen Jacobs, Samuel L. Jackson, Representative Ilhan Omar, Sharon Stone and many more.
“Your light brightened our days,” the actor Forest Whitaker wrote just before midnight, Los Angeles time. “It will continue to brighten our hearts and minds. Let the heavens be blessed as you illuminate the sky.”
