Walt Whitman (1819 –1892) was an American poet, essayist and journalist. A humanist, he was a part of the transition between transcendentalism and realism, incorporating both views in his works. Whitman is among the most influential poets in the American canon, often called the father of free verse. His work was very controversial in its time, particularly his poetry collection Leaves of Grass, which was described as obscene for its overt sexuality.

Whitman's sexuality is often discussed alongside his poetry. Though biographers continue to debate his sexuality, he is usually described as either homosexual or bisexual in his feelings and attractions. Whitman was a religious skeptic: though he accepted all churches, he believed in none. God, to Whitman, was both immanent and transcendent and the human soul was immortal and in a state of progressive development.

A cultural icon, Brando is most famous for his Academy Award-winning performances as Terry Malloy in On the Waterfront (1954) and Vito Corleone in The Godfather (1972), as well as influential performances in A Streetcar Named Desire (1951), Viva Zapata! (1952), Julius Caesar (1953), The Wild One (1953), Reflections in a Golden Eye (1967), Last Tango in Paris(1972) and Apocalypse Now (1979). Brando was also an activist, supporting many causes, notably the African-American Civil Rights Movement and various Native American Movements. In his 1976 biography “The Only Contender,” Brando, who was married three times, openly admitted his homosexuality. He was quoted as saying, "Like a large number of men, I, too, have had homosexual experiences, and I am not ashamed."
