Werner Egk (17 May 1901 – 10 July 1983), born Werner Joseph Mayer, was a German composer.
He was born in the Swabian town of Auchsesheim, today part of Donauwörth, Germany. His family, of Catholic peasant stock, moved to Augsburg when Egk was six. He studied at a Benedictine Gymnasium (academic high school) and entered the municipal conservatory. Egk demonstrated talents as a composer, graphic artist, and writer, and he moved first to Frankfurt to improve his piano talents and then, in 1921, to Munich. There, working as a theater composer and playing in the pit, he married Elizabeth Karl, a violinist. He derived his pen name "Egk" from his wife initials: Elisabeth, geborne Karl (Elisabeth, née Karl). His only son, Titus, was born in 1924.
Egk moved to Berlin in 1928, meeting composers Arnold Schoenberg and Hanns Eisler. He intended to become a cinema composer and accompanied silent films. When radio broadcasting became available to the public, Egk immediately realised its importance as a mass medium and developed operas and radio plays. He was introduced to Hans Fleisch, an important radio executive (also Paul Hindemith's brother-in-law and a Jew), by composer Kurt Weill. He received his first commission for broadcasting from Fleisch's company.
He returned to Munich in 1929 to work for the local radio station and settled in Lochham, a suburb. He became associated with musicians Fritz Büchtger , Karl Marx, and especially, Carl Orff, whom he had met in 1921. His music of the period shows a debt to the compositional style of Igor Stravinsky. He also became friends with new-music conductor Hermann Scherchen and the owners of the music publisher, Schott Music in Mainz. His career as a composer took off with the premiere of his radio opera, Columbus, in July 1933 (staged in April 1934).
