Heretic, Rebel, a Thing to Flout: Langston Hughes—The Prophetic Poetic Voice of the Black Experience. For many folks Langston Hughes is THE great African American Poet. Certainly he was a break out star who won wide audiences among both Blacks and Whites with gritty yet lyrical poems that unflinchingly cast a light on the Black experience—and his personal experience—in America. In doing so he opened the doors for others. Hughes was born in Joplin, Missouri on February 1, 1902.
William Carlos Williams - he was one of the principal poets of the Imagist movement. Williams sought to invent an entirely fresh—and singularly American—poetic, whose subject matter was centered on the everyday circumstances of life and the lives of common people. http://www.poets.org/poetsorg/poet/william-carlos-williams
