German-Dutch composer and early pioneer in computer music.

He studied church music in Braunschweig, composition, piano, analysis and acoustics in Detmold, music representation techniques in Cologne and computer technique in Bonn. He attended and later lectured at the “Darmstädter Ferienkurse” (Darmstadt music summer schools). From 1954 to 1964 Koenig worked in the electronic studio of West German Radio (WDR) producing his electronic compositions Klangfiguren, Essay and Terminus 1 and wrote orchestral and chamber music. Furthermore he assisted other composers, including M. Kagel, F. Evangelisti, Gy. Ligeti, H. Brün and K. Stockhausen (with the realization of Kontakte and Gesang der Jünglinge).

In 1964 Koenig moved to the Netherlands, where he was, until 1986, director and later chairman of the Institute of Sonology at the University of Utrecht. Here he developed his computer composition programs Project 1 (1964) and Project 2 (1966), designed to formalise the composition of musical structure-variants. Both programs had a significant impact on the further development of algorithmic composition systems.
