James Mercer Langston Hughes (February 1,1902 – May 22,1967) was an American poet, social activist, novelist, playwright, and columnist.
He was one of the earliest innovators of the then-new literary art form called jazz poetry. Hughes is best known as a leader of the Harlem Renaissance in New York City. He famously wrote about the period that "the negro was in vogue", which was later paraphrased as "when Harlem was in vogue". He wrote novels, short stories and plays, as well as poetry, and is also known for his engagement with the world of jazz and the influence it had on his writing, as in his book-length poem Montage of a Dream Deferred (Holt, 1951). His life and work were enormously important in shaping the artistic contributions of the Harlem Renaissance of the 1920s.

Langston Hughes is particularly known for his insightful, colorful portrayals of black life in America from the twenties through the sixties.
The critic Donald B. Gibson noted in the introduction to Modern Black Poets: A Collection of Critical Essays (Prentice Hall, 1973) that Hughes “differed from most of his predecessors among black poets . . . in that he addressed his poetry to the people, specifically to black people. During the twenties when most American poets were turning inward, writing obscure and esoteric poetry to an ever decreasing audience of readers, Hughes was turning outward, using language and themes, attitudes and ideas familiar to anyone who had the ability simply to read . . . Until the time of his death, he spread his message humorously—though always seriously—to audiences throughout the country, having read his poetry to more people (possibly) than any other American poet.”
In addition to leaving us a large body of poetic work, Hughes wrote eleven plays and countless works of prose, including the well-known “Simple” books: Simple Speaks His Mind, (Simon & Schuster, 1950); Simple Stakes a Claim, (Rinehart, 1957); Simple Takes a Wife, (Simon & Schuster, 1953); and Simple’s Uncle Sam (Hill and Wang, 1965). He edited the anthologies The Poetry of the Negro and The Book of Negro Folklore, wrote an acclaimed autobiography, The Big Sea (Knopf, 1940), and cowrote the play Mule Bone (HarperCollins, 1991) with Zora Neale Hurston.
