Hughes brought a varied and colorful background to his writing. Before he was 12 years old he had lived in six different American cities. When his first book was published, he had already been a truck farmer, cook, waiter, college graduate, sailor, and doorman at a nightclub in Paris, and had visited Mexico, West Africa, the Azores, the Canary Islands, Holland, France, and Italy. As David Littlejohn observed in his Black on White: A Critical Survey of Writing by American Negroes: "On the whole, Hughes’ creative life [was] as full, as varied, and as original as Picasso’s, a joyful, honest monument of a career. There [was] no noticeable sham in it, no pretension, no self-deceit; but a great, great deal of delight and smiling irresistible wit. If he seems for the moment upstaged by angrier men, by more complex artists, if ‘different views engage’ us, necessarily, at this trying stage of the race war, he may well outlive them all, and still be there when it’s over. … Hughes’ [greatness] seems to derive from his anonymous unity with his people. He seems to speak for millions, which is a tricky thing to do.
