Broadway actor Kyle Jean-Baptiste died Friday night at 21, and as news of his death spread in the theater community, Ansel Elgort, Jean-Baptiste’s former classmate, remembered him in a series of tweets.

Elgort wrote that he and Jean-Baptiste acted in a high school production of Hairspray while attending New York City’s famed performing arts high school, LaGuardia. “What I remember most above his talent was his warmth,” Elgort wrote.

Other stars like Kristen Chenowith, Jesse Tyler Ferguson, and Josh Groban also shared their condolences on Twitter.

Lin-Manuel Miranda, whose play Hamilton opened on Broadway this month, remembered Jean-Baptiste, and tweeted that he would postpone Saturday’s #Ham4Ham show — a regular five-minute performance from Hamilton that’s posted on YouTube for non-New Yorkers to experience the show — in the actor’s honor. Jean-Baptiste, who made history this month when he became the youngest and first black actor to portray Jean Valjean in Les Miserables, had performed with Miranda for the experience.
