John Simon, one of the nation’s most erudite, vitriolic and vilified culture critics, who illuminated and savaged a remarkable range of plays, films, literature and art works and their creators for more than a half-century, died on Sunday in Valhalla, N.Y. He was 94.

His death, at Westchester Medical Center, was confirmed by his wife, Patricia Simon .

In an era of vast cultural changes, Mr. Simon marshaled wide learning, insights and acid wit for largely negative reviews and essays that appeared in New York magazine for nearly 37 years, until his dismissal in 2005, and in The Hudson Review, The New York Times, Esquire, National Review, The New Leader and other publications.

In a style that danced with literary allusions and arch rhetoric — and composed with pen and ink (he hated computers) — he produced thousands of critiques and a dozen books, mostly anthologies of his own work. While English was not his native language, he also wrote incisive essays on American usage, notably in the 1980 book “Paradigms Lost: Reflections on Literacy and Its Decline.”

Born in Yugoslavia and educated at Harvard, Mr. Simon was an imperious arbiter who, unlike daily press critics, foraged widely over fields of culture and entertainment at will, devouring the Lilliputians with relish. He regarded television as trash and most Hollywood films as superficial. His formula for an ultimate triumph on Broadway: “A loud, vulgar musical about Jewish Negroes.”
