Raspy-voiced and brassy, Rivers was always self-deprecating, foul-mouthed and politically incorrect. A master of reinvention, she endured in show business because of her tenacious work ethic — which she credited to her “immigrant mentality.”

Comedians typically push the edge of the envelope, but Rivers proved time and again that she didn’t even see the envelope. To her fans, she was as shocking as she was endearing.

“The way she is funny, she tells the truth according to herself,” the late film critic Roger Ebert wrote in 2010. “She hates some people. She has political opinions. Her observations are so merciless and her timing so precise that even if you like that person, you laugh. She is a sadist of comedy, unafraid to be cruel — even too cruel.”
