Heinrich Schütz was a German composer and organist, generally regarded as the most important German composer before Johann Sebastian Bach and often considered to be one of the most important composers of the 17th century. He wrote what is traditionally considered to be the first German opera, Dafne, performed at Torgau in 1627, the music of which has since been lost. He is commemorated as a musician in the Calendar of Saints of the Lutheran Church on 28 July with Johann Sebastian Bach and George Frideric Handel.
