Georg Nees (23 June 1926 – 3 January 2016) was a German academic who was a pioneer of computer art and generative graphics.
Nees was active as an industrial mechanic and software engineer at Siemens AG in Erlangen when he began programming artistic graphics, sculptures and films in 1964. After these were introduced in Bense’s colloquium, an exhibition took place in the Stuttgart Studiengalerie in January of 1965. Nees began studies in philosophy at the Universities of Erlangen-Nürnberg and Stuttgart the same year. He earned his doctorate in 1969 with a dissertation on "Generative Computer Graphics", which translated Max Bense’s foundational terms of philosophical aesthetics into a program code. In 1970, Nees held his first lectures on computer graphics at the University of Erlangen-Nuremberg. In 1977 he became honorary professor in Angewandte Informatik at the University of Erlangen and writer at SEMIOSIS, an international journal for semiotics and aesthetics.
From 1964 Nees was working with computer graphics, sculptures and film – both producing and theorizing about it. In 1965 Nees along with two other pioneers within the field of early computer art, Frieder Nake and A. Michael Noll, organised exhibitions of computer graphics calling it Computer Art:
- 1965.02.05 - 1965.02.19, Georg Nees, Studien-Galerie University of Stuttgart
- 1965.04.06 - 1965.04.24, A. Michael Noll & Bela Julesz, Howard Wise Gallery New York City
- 1965.11.05 - 1965.11.26, Frieder Nake & Georg Nees, Galerie Wendelin Niedlich Stuttgart
Nees participated in various biennials and art festivals, including the Biennale film/art festival in Venice in 1969 and 1970; the Biennale in Nürnberg in 1969 and 1971; Prinzip Zufall in Ludwigshafen in 1992; and Digital Konkret 1 in Bonn 1995.
