Candide is an operetta with music composed by Leonard Bernstein, based on the novella of the same name by Voltaire. The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel. The primary lyricist was the poet Richard Wilbur. Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, Leonard Bernstein, John Mauceri, and John Wells. Maurice Peress and Hershy Kay contributed orchestrations. Although unsuccessful at its premiere, Candide has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity. It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.
