Critic Orville Prescott of The New York Times called the novel "the most impressive work of fiction by an American Negro which I have ever read", and felt it marked "the appearance of a richly talented writer".[16] Novelist Saul Bellow in his review found it "a book of the very first order, a superb book...it is tragi-comic, poetic, the tone of the very strongest sort of creative intelligence".[17] George Mayberry of The New Republic said Ellison "is a master at catching the shape, flavor and sound of the common vagaries of human character and experience".[18]
Anthony Burgess described the novel as "a masterpiece".[19]
In 2003, a sculpture titled "Invisible Man: A Memorial to Ralph Ellison" by Elizabeth Catlett, was unveiled at Riverside Park at 150th Street in Manhattan, opposite from where Ellison lived and three blocks from the Trinity Church Cemetery and Mausoleum, where he is interred in a crypt. The 15-foot-high, 10-foot-wide bronze monolith features a hollow silhouette of a man and two granite panels that are inscribed with Ellison quotations.[20]
