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 and was known as embodying various aspects of this counterculture, such as his views on drugs, hostility to bureaucracy and openness to Eastern religions. He was one of many influential American writers of his time known as the Beat Generation, which included famous writers such as Jack Kerouac and William S. Burroughs.
