Irwin Allen Ginsberg (/ˈɡɪnzbərɡ/; June 3, 1926 – April 5, 1997) was an American poet and one of the leading figures of both the Beat Generation of the 1950s and the counterculture that soon would follow. He vigorously opposed militarism, economic materialism and sexual repression. Ginsberg is best known for his epic poem "Howl", in which he denounced what he saw as the destructive forces of capitalism and conformity in the United States.
In 1957, "Howl" attracted widespread publicity when it became the subject of an obscenity trial, as it depicted heterosexual and homosexual sex at a time when sodomy laws made homosexual acts a crime in every U.S. state. "Howl" reflected Ginsberg's own homosexuality and his relationships with a number of men, including Peter Orlovsky, his lifelong partner. Judge Clayton W. Horn ruled that "Howl" was not obscene, adding, "Would there be any freedom of press or speech if one must reduce his vocabulary to vapid innocuous euphemisms?"
