Today in Labor History May 31, 1819: Poet Walt Whitman was born. Whitman published his first and most famous collection of poems, Leaves of Grass, in 1855, using his own money. It was criticized as obscene for its sensuality. During the Civil War, he volunteered in hospitals caring for the wounded. Many believe Whitman was gay or bisexual, based on his writings, though it is disputed by some historians. Oscar Wilde met Whitman in the United States in 1882 and told the homosexual-rights activist George Cecil Ives that Whitman's sexual orientation was beyond question—"I have the kiss of Walt Whitman still on my lips." Whitman is considered by many to be Americas first and greatest poet. He inspired many who came after him, including Ezra Pound, Langston Hughes, Kerouac, Ginsberg, Ferlinghetti, Gary Snyder and June Jordan.
