On Friday, acclaimed African American actor Chadwick Boseman died at the age of 43, after battling colon cancer for the past four years.

Boseman was best known as the star of Black Panther, the 2018 Marvel superhero movie that grossed over $1.3 billion worldwide.

Boseman’s family shared the news on Twitter on Friday evening, revealing that the actor “died in his home, with his wife and family by his side.”

“It is with immeasurable grief that we confirm the passing of Chadwick Boseman. Chadwick was diagnosed with stage III colon cancer in 2016, and battled with it these last 4 years as it progressed to stage IV.”

During his career, Boseman became popular for portraying several prominent Black figures in major Hollywood films. He played the role of Jackie Robinson in 42, a biopic on the late Robinson, the first Black baseball player to break into the MLB.

Boseman’s other prominent roles include James Brown in the film Get On Up, and Thurgood Marshall in Marshall.

Boseman graduated from Howard University in 2000, and fellow Howard alum and current Democratic vice presidential nominee Kamala Harris sent her condolences on Friday.

Joining Harris were several other prominent Black figures, including Bernice King, the daughter of Dr. Martin Luther King Jr. and Coretta Scott King.

King shed light on the fact that few knew of Boseman’s battle with cancer until his death.

We never know what people are enduring. Humans…we are wonders.

Thank you, Chadwick, for gifting us with your greatness in the midst of a painful struggle. #ChadwickBoseman pic.twitter.com/YDLOLHxop6

Legendary songstress Toni Braxton shared a poignant moment from her relationship with Boseman.

Our makeup artists are friends and he used to get on the phone and ask me to sing “You Mean The World To Me” because it was his favorite song of mine and now this song will be forever dedicated to him. Rest In Power King. https://t.co/SnSn1UdhUB

And on Saturday morning, Barack and Michelle Obama shared their condolences.

Chadwick came to the White House to work with kids when he was playing Jackie Robinson. You could tell right away that he was blessed. To be young, gifted, and Black; to use that power to give them heroes to look up to; to do it all while in pain – what a use of his years. https://t.co/KazXV1e7l7

Only Chadwick could embody Jackie Robinson, Thurgood Marshall, and T’Challa. He, too, knew what it meant to persevere. To summon real strength. And he belongs right there with them as a hero—for Black kids and for all our kids. There’s no better gift to give our world. ❤ pic.twitter.com/t2tjZDMxNT
