Richard Lewis, an acclaimed comedian known for exploring his neuroses in frantic, stream-of-consciousness diatribes while dressed in all-black, leading to his nickname The Prince of Pain, has died. He was 76.

Lewis, who revealed he had been diagnosed with Parkinson’s disease in 2023, died at his home in Los Angeles on Tuesday night after suffering a heart attack, according to his publicist Jeff Abraham.

A regular performer in clubs and on late-night TV for decades, Lewis also played Marty Gold, the romantic co-lead opposite Jamie Lee Curtis, in Anything But Love and the reliably neurotic Prince John in Mel Brooks’ Robin Hood: Men In Tights. He reintroduced himself to a new generation opposite Larry David in Curb Your Enthusiasm.

“I’m paranoid about everything in my life. Even at home. On my stationary bike, I have a rear-view mirror, which I’m not thrilled about,” he once joked onstage.

To Jimmy Kimmel he said: “This morning, I tried to go to bed. I couldn’t sleep. I counted sheep but I only had six of them and they all had hip replacements.”

Comedy Central named Lewis one of the top 50 stand-up comedians of all time and he earned a berth in GQ magazine’s list of the 20th Century’s Most Influential Humorists. He lent his humour for charity causes, including Comic Relief and Comedy Gives Back.

“Watching his stand-up is like sitting in on a very funny and often dark therapy session,” the Los Angeles Times said in 2014.

The Philadelphia’s City Paper called him “the Jimi Hendrix of monologists.” Mel Brooks once said he “may just be the Franz Kafka of modern-day comedy.”
