Emotional outpourings have appeared on Twitter and Facebook as friends and fans learned of Patrice O’Neal’s death Tuesday. The comedian, known for his sharp and often shocking social commentary, died following complications from a stroke at the age of 41.

Jonathan Brandstein, O’Neal’s manager, said he died in a New York-area hospital, reports the Associated Press:

“Many of us have lost a close and loved friend; all of us have lost a true comic genius,” Brandstein said in a statement.

A frequent guest on several TV and radio shows, including “The Opie and Anthony Show” and “Tough Crowd With Colin Quinn,” O’Neal recently helped grill Charlie Sheen during his roast on Comedy Central. Sheen was one of many who have expressed their grief on social media, the Associated Press reports:

Sheen said in a tweet Tuesday, “The entertainment world as well as the world at large lost a brilliant man.”

He added, “Patrice had that rare ‘light’ around him and inside of him. I only knew him for the few days leading up the Roast. Yet I will forever be inspired by his nobility, his grace and his epic talent. My tears today are for the tremendous loss to his true friends and loving family.”

Fahima Haque of the Root DC found several tweets from fellow comedians and entertainers:
