Allen Ginsberg was a prominent Beat poet known for his poem "Howl". He came from a family of poets but left academia, being openly homosexual and anti-establishment. Ginsberg befriended other Beat writers like William Burroughs and Jack Kerouac in New York City and San Francisco. He wrote "Howl" in 1955, employing long lines and repetition like Walt Whitman and William Blake to protest post-war America through mystical visions and the rhythm of breath and sound.
