Raymond John Leppard was a British-American conductor, harpsichordist, composer and editor. In the 1960s, he played a prime role in the rebirth of interest in Baroque music; in particular, he was one of the first major conductors to perform Baroque opera, reviving works by Claudio Monteverdi, Francesco Cavalli and Jean-Philippe Rameau. He conducted operas at major international opera houses and festivals, including the Glyndebourne Festival where he led the world premiere of Nicholas Maw's The Rising of the Moon, the Metropolitan Opera and the Royal Opera House. He composed film scores such as Lord of the Flies and Alfred the Great.
