There are two famous Invisible Man books. One is a novel by Ralph Ellison which deals with questions of African-American civil rights and identities in twentieth century America, and the other is a science fiction novella by H.G. Wells in which a man becomes irreversibly invisible.
In the H.G. Wells novel, as Richard describes, the apparent 'gift' of invisibility soon becomes a curse, driving Griffin, the invisible man, insane. The book was adapted into a film in 1933.
