born in 1949, I have lived since 1969 in Berlin/Germany, Diploma in Political Science and Ph.D. in Economics. Up to 1997 I spent about 2/3 of my professional life on research, writing books and teaching, and 1/3 of it producing art. In 1983/4 and 1987-1991 I lived in the USA (Harvard/MA and UNC/NC). 9 years ago I decided to make producing art my main activity and I started to market it. Around the same time I began using the computer as my main drawing tool. I use a PC and a graphic tablet and most of the time "Painter" (Fractal Design/Metacreations/Corel).
