Irwin Allen Ginsberg (June 3, 1926 – April 5, 1997) was an American poet and writer. As a student at Columbia University in the 1940s, he began friendships with William S. Burroughs and Jack Kerouac, forming the core of the Beat Generation. He vigorously opposed militarism, economic materialism, and sexual repression, and he embodied various aspects of this counterculture with his views on drugs, sex, multiculturalism, hostility to bureaucracy, and openness to Eastern religions.

Most of Ginsberg's very early poetry was written in formal rhyme and meter like that of his father, and of his idol William Blake. His admiration for the writing of Jack Kerouac inspired him to take poetry more seriously. In 1955, upon the advice of a psychiatrist, Ginsberg dropped out of the working world to devote his entire life to poetry. Soon after, he wrote Howl, the poem that brought him and his Beat Generation contemporaries to national attention and allowed him to live as a professional poet for the rest of his life.
