Kornbluth was born in 1959 to mother "Bunny" and father Paul, the oldest of four children. Raised in New York City, he briefly attended Princeton University but dropped out, never completing his undergraduate degree. He worked as a copyeditor in New York before moving to San Francisco in 1987. He is married to wife Sara, with whom he has a son.
Kornbluth's live and filmed works are almost entirely solo monologues based closely on events and people his life, his upbringing, and his career. As such he is among a small group of artists that include Eric Bogosian, Lily Tomlin, and Spalding Gray.
Most of Kornbluth's monologues relate to personal and societal ethics, self-fulfillment, and the role of the individual in society, drawing a connection between his own personal foibles and larger issues of citizenship. Playing a hapless, sincere, and sometimes buffoonish everyman caught up in world events, he demonstrates the relevance of these concepts to daily life. His live performances, occasionally include a question-and-answer session with academic lawyers or other experts and scholars. Despite the serious messages and somewhat dry themes his works are all lighthearted and highly humorous.
