Richard Pryor, the caustic yet perceptive actor-comedian who lived dangerously close to the edge both on stage and off, has died, his ex-wife said Saturday. He was 65.

Pryor died of a heart attack at his home in the San Fernando Valley sometime late Friday or early Saturday, Flyn Pryor said. He had been ill for years with multiple sclerosis, a degenerative disease of the nervous system.
