Georg Nees (23 June 1926 – 3 January 2016) was a German academic who was a pioneer of computer art and generative graphics.

He studied mathematics, physics and philosophy in Erlangen and Stuttgart and was scientific advisor at the SEMIOSIS, International Journal of semiotics and aesthetics.

In 1969, his thesis was published as a book entitled "Generative Computergraphik" and also included examples of program code and graphics produced thereby.

[8][9] The exhibition, titled computer graphik took place at the public premises of the "Study Gallery of Stuttgart College".

[11] In the catalog of the Biennale 1969 Nuremberg, Nees describes how the computer program controlled the milling machine so that instead of a workpiece, a sculpture was created.

Frieder Nake explains how this graphic was created: ″In fact, the picture does consist of one continuous path of arcs.

… The length and radius of the individual arcs are randomly chosen within the limits defined by the programmer … The picture in it present form is due to a fairly serious programming error … It was designed to be less complex and it had to be ended manually because of the error.″[17] Nees worked with the Siemens System 2002[18] to create aesthetic graphics, such as the graphic ″gravel ″ (Schotter) in 1968.

[20] When writing the program Nees introduced commands for random numbers, which produced from a designated point on the resulting chaos.

Robert J. Krawczyk wrote in his text A Shattered Perfection: Crafting a Virtual Sculpture: ″Georg Nees’s Gravel Stones … What attracted me to this piece was the simplicity of the concept and the overall interpretation of transforming order into disorder.

[29][30] In 1985, Alex Kempkens asked Nees whether he wished to participate in the exhibition Bilder Images Digital in the ″Gallery of the Artist″[31] in Munich, which was planned for October 1986.

[34] Nees wrote in the exhibition catalog: My own computer graphics in the spring of 1986, I understand as studies on ambience, as they could be synthesized by perhaps a future Reagiblen machines.

A mental concept which one can only consider cautiously and which however can call in question all the hitherto binding definitions of the inviolability of the human creative capacity.

Looking at the multi-patterned constructions in Nees' graphics, with their floating ellipsoids, crystalloid spheres and bizarre forms, one cannot help but acknowledge and appreciate their atmospheric and inspiration-inducing effects.
