UPDATED: The actress, best known as Katherine Chancellor, won a Daytime Emmy in 2008 following a Lifetime Achievement Award honor in 2004.

The Young and the Restless star Jeanne Cooper, who played Katherine Chancellor on the daytime soap for four decades, died in her sleep Wednesday morning at 84.

"Mom passed this morning. She was in peace and without fear. U all have been incredible in your love. In her name share it 2 day with others," Cooper's son, actor Corbin Bernsen, wrote on Twitter on Wednesday.

Bernsen shared in a lengthier message posted on his Facebook that he "was going to visit this afternoon, thought I had time. Reminder to self -- time is a precious thing. I too am at peace however. I said my goodbyes several times over during the last few weeks." He shared that his sister was by his mother's side when she died.

In an earlier update, Bernsen called his mother "a beacon whose bright light will not easily fade away" and "a boxer who will not easily give up."

“Jeanne Cooper was a legend in daytime and a beloved member of our Y&R family,” said Steve Mosko, president of Sony Pictures TV, which produces Young and the Restless. “She touched the lives of millions, who watched her every day over the past 40 years. We send our sincerest condolences to her family as we also celebrate her wonderful life.”

Cooper received 10 Daytime Emmy Award nominations, winning a Daytime Emmy in 2008 and a Lifetime Achievement Award in 2004. She was honored with a star on the Walk of Fame in 1993 and was nominated for two Primetime Emmys, including one for playing Bernsen's mother in L.A. Law.

Prior to Young and the Restless, Cooper's career began in the 1950s with the film The Redhead From Wyoming, before appearing later in TV series like Ironside and Perry Mason.
