German composer, pianist, and educator, also known as Georg Frauenfelder, who composed music for the Luftwaffe and for other military groups during World War II. Josef Matthias Hauer dedicated his book Twelve-Tone Technique (1925) to Heiss, who later claimed to have collaborated with Hauer on its contents. He introduced twelve-tone music at Darmstadt in 1946 and composed electronic music at the Studio for Electronic Music (WDR) in Cologne in 1956, where his Elektronische Komposition I was performed and broadcast in a concert of the Musik der Zeit series on 30 May 1956. He then founded a studio of his own in Darmstadt. He died in Darmstadt on 6 December 1966, aged 68.
