Guillaume Du Fay was a composer and music theorist of early Renaissance music, who is variously described as French or Franco-Flemish. Considered the leading European composer of his time, his music was widely performed and reproduced. Du Fay was well-associated with composers of the Burgundian School, particularly his colleague Gilles Binchois, but was never a regular member of the Burgundian chapel himself. August 21, 1397 – November 27, 1474; died at 77. Alive at the same time as Leonardo da Vinci, Christopher Columbus, Joan of Arc, Jan Hus, and François Villon. Wiki link
