What role did Jeanne Cooper play on The Young and the Restless?

Late actress Jeanne Cooper's Katherine Chancellor was a significant character on The Young and the Restless. Acccording to CNN Entertainment report dated May 9, 2013, several co-stars appreciated the actress' work after her demise.
Kate Linder, who plays Esther Valentine on The Young and the Restless, stated that Cooper was her “mentor and an amazing actress and friend.” Meanwhile, show creator Lauralee Bell shared a statement:
"Jeanne was the matriarch of the show in every sense of the word."
According to the same media outlet, Katherine was reportedly introduced in an effort to increase the show's struggling ratings. When co-creator William Bell's plan was proven to be successful, Jeanne Cooper was signed to a contract. With time, Cooper became one of the longest-running cast members in the show, ending her nearly 40-year tenure on May 3, 2013, five days before her death.
Throughout Katherine's tenure on the show, her storylines focused on her chaotic relationship with Jill Abbott. Their rivalry was one of the longest-running feuds in the history of American soap operas. It was fueled by Jill's affair with Katherine's husband, Phillip Chancellor II.
When Katherine attempted to win him back, it led to his death. After Phillip's demise, the two women fought over Jill and Phillip's son, Phillip III, as well as several other figures, including Rex Sterling.
A major plot twist in 2003 that shook things up in Genoa City, revealed that Katherine and Jill were mother and daughter. However, this plot was undone in 2009 by head writer Maria Arena Bell, when it was depicted that Tucker McCall was Katherine's child.
