LOS ANGELES - Jeanne Cooper, the enduring soap opera star who played grande dame Katherine Chancellor for nearly four decades on "The Young and the Restless," has died.
She was 84.
Cooper died Wednesday morning in her sleep, her son the actor Corbin Bernsen wrote on Facebook. CBS says the family confirmed her death to the network.
She had been in a Los Angeles-area hospital, according to Bernsen's spokesman, Charles Sherman, who said the cause of death was not immediately available.
Bernsen wrote on his Twitter account in April that his mother faced an "uphill battle" for an undisclosed illness. In subsequent days he wrote of her gradual improvement and said she'd been taken off breathing equipment.
Cooper's role on "The Young and the Restless" earned her repeated Daytime Emmy Award nominations and a trophy for best actress in a drama series in 2008.
Her 30-year marriage to Harry Bernsen ended in divorce.
The couple have three children, Corbin, Caren and Collin, and eight grandchildren.
