Harold Bloom, the prodigious literary critic who championed and defended the Western canon in an outpouring of influential books that appeared not only on college syllabuses but also — unusual for an academic — on best-seller lists, died on Monday at a hospital in New Haven . He was 89.

His death was confirmed by his wife, Jeanne Bloom, who said he taught his last class at Yale University on Thursday.

Professor Bloom was frequently called the most notorious literary critic in America . From a vaunted perch at Yale, he flew in the face of almost every trend in the literary criticism of his day. Chiefly he argued for the literary superiority of the Western giants like Shakespeare, Chaucer and Kafka — all of them white and male, his own critics pointed out — over writers favored by what he called “the School of Resentment,” by which he meant multiculturalists, feminists, Marxists, neoconservatives and others whom he saw as betraying literature’s essential purpose.

“He is, by any reckoning, one of the most stimulating literary presences of the last half-century — and the most protean,” Sam Tanenhaus wrote in 2011 in The New York Times Book Review, of which he was the editor at the time, “a singular breed of scholar-teacher-critic-prose-poet-pamphleteer.”
