I was born in Stockholm on the 9th of October, 1938. Studied philosophy, mathematics and physics at Stockholm University. In 1968 I took my doctor's degree at Stockholm University in elementary particle physics.
After that I devoted myself to light and colour, not only from a physical but also from a perceptual, phenomenological, aesthetical as well as a philosohical point of view. Of course, in that connection I run into Goethe's Theory of Colour and his criticism against the Newtonian theory of colour. I edited and commented a Swedish edition of his "Entwurf einer Farbenlehre" (1976) and after that I have been extensively lecturing on colour -- much inspired by Goethe's view -- as well as written a number of articles and books on colour theory (in Swedish).
My research work, starting with computational theories for colour vision, as in the report "Colour and Physics" (1973), has since mainly dealt with the assessment of colour rendering properties of artificial light sources, in collaboration with groups at Fysisk institutt in Oslo and at the School of Architecture, KTH, Stockholm.
