Saying Goodbye to Jeanne

In 2013, shortly after a round of promotion for the Y&R 40th anniversary, Cooper became ill due to an infection. She died on May 8, 2013, in a Los Angeles hospital. In addition to the infection, Cooper had been a heavy smoker most of her adult life and suffered from chronic obstructive pulmonary disease. Her final Y&R scene was taped March 26, 2013 (the exact date of Y&R's 40th anniversary) and aired on May 3, 2013. “Mom passed this morning”, her son, Corbin Bernsen, revealed on Twitter the day of her death. “She was in peace and without fear.

Cooper had to take a medical leave in October 2011 and her part on the soap was temporarily recast with veteran actress Michael Learned. However, the next month, Cooper confirmed she was returning to the set. She returned as part of the show on December 23, 2011. She taped her last scene on the show in March 2013 on the same day as the Young and the Restless 40th anniversary and this scene aired on May 3, 2013, five days before her death.
A tribute episode of The Young and the Restless in honor of Jeanne Cooper, made up of clips, cast memories and interviews, was shown on May 28, 2013 on CBS. Her character, Katherine, died offscreen a few months later after a trip around the world.
