The Broadway community took to Twitter on Saturday to mourn the loss of a young talent.
"Shocked and saddened to have lost one of Broadway's youngest treasures," tweeted Tony Award-nominee Joshua Henry. Teal Wicks, starring in Finding Neverland, called him "a new friend and a shining star".
After making stage history as the first black Valjean, New York native Jean-Baptiste told Playbill: "I did not immediately think of it as making history. This was my dream since I was a little boy. This incredible team of creatives presented an opportunity to play a part I have dreamed of playing since I was introduced to theatre, and I am forever grateful.
"I felt a huge amount of responsibility to do right by them and to honour this iconic material."
In one of his last tweets, sent on Tuesday, Jean-Baptiste showed gratitude for his friends and fans: "I thank everyone who supported me and still does. I will never forget this experience. Onwards and upwards," he wrote. "Nothing but love."
