 Recently, research by Howard Mancing, a Cervantes scholar and Professor of Spanish Literature at Purdue University, uncovered an earlier use of the line "To dream the impossible dream, to fight the unbeatable foe," which was made famous in Wasserman's "Man of La Mancha".The lines were actually invented for publicity matter that accompanied an earlier stage adaptation of "Don Quixote" by the American playwright Paul Kester, first performed in 1908.The phrase "To each his Dulcinea", featured in Wasserman's play, was also first used in the Kester play.
