"In 1903, George Bernard Shaw published his Man and Superman, a comedy based on the Don Juan legend and expanding upon Shaw's conception of social evolution; that is the earliest citation we have for the English compound superman. Shaw's use of the term is clearly in allusion to Nietzsche's conception, and immediately thereafter superman became the translation of choice for Ubermensch, gradually, however, acquiring the looser, more generalized denotation of "any man with extraordinary powers or abilities.""
