The comedians

The Catskill Mountains resort circuit (roughly the 1920s through the 1960s heyday) where Jewish New York summered and a generation of comedians learned the trade doing multiple shows nightly for the toughest easy audience in history. Its alumni and heirs — from Sid Caesar and Mel Brooks through Joan Rivers, Jackie Mason, Jerry Lewis, and beyond — carried the timing and the stance into television and film, which is how a regional resort style became the backbone of American comedy.

For the classic register: Mel Brooks (the 2000 Year Old Man with Carl Reiner is a masterclass in the argued-with-history voice) and Joan Rivers for velocity and nerve. For the observational turn the tradition took on television: Seinfeld. For the anxious interior monologue: the early stand-up of Woody Allen, whose complicated later biography readers can weigh for themselves. Each is a different branch of the same tree.

Structurally, yes — the self-aware narrator, the neurotic monologue, the answered-with-a-question rhythm, and the writers-room culture that Jewish comics and writers built at mid-century remain load-bearing across the industry. The tradition's children include people of every background now, which is what successful traditions do: they stop being property and become grammar.
