Just days after his 65th birthday, groundbreaking comedian Richard Pryor died Saturday of a heart attack.

Pryor, who had been ill with multiple sclerosis, died at Encino Hospital near Los Angeles at 7:58 a.m. PT. Jennifer Lee Pryor tried to revive him at their home before paramedics arrived and took him to the hospital, she said.

"He enjoyed life right up until the end," she said, adding that Pryor had been laughing a lot and was in good spirits in the two weeks preceding his death. "At the end there was a smile on his face."
