From 1975 to 1985, Isa Genzken (1948, Bad Oldesloe, Germany) used the computer to design a series of sculptures known as Ellipsoids and Hyperbolos. The artist explains that she wanted to use the ‘arts of calculation’ to create ‘mathematically correct’ works. She produced a series of computer-generated drawings of geometric shapes with the technical support of Ralph Krotz, a physics student at the University of Cologne. These were printed at 1:1 scale using a plotter and given to a cabinet maker who produced the sculptures in wood. She first exhibited the drawings alongside these works in 1979. The application of scientific principles and industrial methods of fabrication within these works can be seen to borrow from conceptual and minimalist art traditions.
