A pretty great gay free verse poet and
beatnik. His most famed work is Howl, a three part poem (with a poetic
footnote) that was
Ginsberg's response to the social climate in America, in addition to parts of his life. Became very involved in spirituality, becoming a Buddhist in the 1960s. He wrote tons of poems, which I definitely recommend you read. Though later on his stuff got weirder.
Allen Ginsberg was an excellent
poet, but in his later years he wrote some pretty weird
poems, like, "Sphincter" (which,
albeit it being strange is funny).
