Kristoff St. John, the actor best-known for portraying Neil Winters on CBS’ long-running daytime soap “The Young and the Restless,” has died. He was 52.

His attorney Mark Geragos confirmed the news to Variety. Geragos also posted on Twitter, saying, “Few men had the unique strength, courage & sensitivity that @kristoffstjohn1 lived every single minute of every day. He impacted everyone he met and millions who he inspired and in turn admired him. On behalf of @MiaStJohnBoxer & @TheStJohnFamily thank you for all of your love.”

The Daytime Emmy Awards also noted St. John’s death via Twitter. “It is with unbelievable sadness that we say goodbye to our friend, #DaytimeEmmys winner @kristoffstjohn1. @YandR_CBS RIP.”

CBS and Sony Pictures Television, producer of “Young & the Restless,” called St. John’s death “heartbreaking” in a statement.

“He was a very talented actor and an even better person. For those of us who were fortunate enough to work with him on ‘The Young and the Restless’ for the last 27 years, he was a beloved friend whose smile and infectious laugh made every day on set a joy and made audiences love him,” CBS and SPT said. “On behalf of the Y&R cast and crew, CBS and Sony Pictures Television, we offer our heartfelt sympathy to his family and loved ones, especially his two daughters, Paris and Lola.”

St. John received numerous awards, including nine Daytime Emmys, over the 25 years he worked on “The Young and the Restless.” His first major role on a soap opera was on NBC’s “Generations.” The show was canceled in 1991.

St. John’s work on “Young and the Restless” was hailed by fans as he established one of the show’s first major African-American characters. He played a Stanford University graduate and business executive who had many ups and downs in his personal life.

.@YRInsider has been my guilty pleasure for 20 years. This is just heartbreaking. Kristoff St. John’s character was so revolutionary because he & @victoriarowell represented the only black family on Y&R, the no. 1 soap. Kristoff is appreciated and will be sorely missed. https://t.co/dEeC4Ef5y9 — Jemele Hill (@jemelehill) February 4, 2019
