An insightful essay on what made Newhart’s work genius, by Jason Zinoman at The New York Times:

Before basically inventing the hit stand-up special, with the 1960 Grammy-winning album “The Button-Down Mind of Bob Newhart” — that doesn’t even count his pay-per-view event broadcast on Canadian television that some cite as the first filmed special — he was a soft-spoken accountant who had never done a set in a nightclub. That he made a classic with so little preparation is one of the great miracles in the history of comedy.

Newhart was a master of the slow build and used silence and his stammer as power tools.

Newhart went straight to the top. Unlike other comics, he didn’t have years of playing small gigs to refine his act before hitting it big. He went from nowhere to a #1 album and had to learn his craft in the spotlight.

Newhart repeats the hilarious story about how his wife met Don Rickles. The Newharts and Rickles became lifelong friends. Rickles was an insult comic who spewed racist jokes at a time when a person could do those things, and it was clear they were demonstrating how racism was stupid. But offstage, Don Rickles was, by all accounts, a kind and gracious man—the opposite of his onstage persona.

Newhart shrugs and does not explain how he and Rickles became close friends. But I think a big part of it is that they were both good men who played Rat Pack shows but were not interested in the boozing, philandering lifestyle. They were family men.
