Adler, Larry (1914-2001), an American harmonica player, is considered the greatest player in the history of the instrument. Adler gained acclaim for his virtuoso playing in pop music, jazz, and classical music. Such composers as Ralph Vaughan Williams of the United Kingdom and Joaquin Rodrigo of Spain wrote music especially for him. In a career that lasted more than 70 years, Adler also worked as a composer and teacher.
