(CNN) -- Jeanne Cooper, who played Katherine Chancellor, the "Dame of Genoa City," on "The Young and the Restless," has died. She was 84. 

Her death was confirmed by her son, actor Corbin Bernsen, on his Twitter account. 

"Mom passed this morning," Bernsen posted. "She was in peace and without fear." 

Cooper had been suffering from an undisclosed illness. The cause of death was not given. 

Cooper was already a well-established TV actress when she took the role of Chancellor in 1973. "The Young and the Restless" was struggling in the ratings and its creator, William J. Bell, wanted to spice things up. 

"Jeanne was the matriarch of the show in every sense of the word," said Lauralee Bell, Christine/Cricket on "The Young and the Restless" and William Bell's daughter. 

"When you did work you were proud of, you'd hope for approval or a 'good job' from Jeanne as a child would from a parent. When things got too tense, she'd break the tension with her amazing wit. She would teach the younger actors without ever talking down to them. In fact, she would raise them up," said Bell. "She always had my back and my parents (and our whole family) always had hers." 

Kate Linder, another member of "The Young and the Restless" cast, said Cooper was her "mentor and an amazing actress and friend." Linder, Esther Valentine on the show, said, "When Jeanne welcomed you into her life, you knew it and it was a fantastic feeling. This is truly the end of an era, not just for fans of 'The Young and the Restless' but for all of the people she touched throughout her long and distinguished career and life."  QUESTIONS:
