Naphtali "Tuli" Kupferberg (September 28, 1923 – July 12, 2010) was an American counterculture poet, author, singer, cartoonist, publisher, and co-founder of the rock band The Fugs.

[2] Kupferberg reportedly appears in Ginsberg's poem Howl as the person "who jumped off the Brooklyn Bridge and walked away unknown and forgotten into the ghostly daze of Chinatown soup alleyways & firetrucks, not even one free beer."

[7] He appeared as a machine-gun-toting soldier policing Manhattan in W.R.: Mysteries of the Organism, a 1971 film about the revolutionary psychiatrist Wilhelm Reich by Dušan Makavejev.

An anti-police-brutality skit from his Revolting Theatre[8] appeared in the 1971 underground film Dynamite Chicken directed by Ernest Pintoff, and featuring Richard Pryor.

[9] Kupferberg suffered a stroke in April 2009 at his home in New York City, which left him severely visually impaired and in need of regular nursing care.
