Erwin Schrödinger's Color Theory

Dr. Keith Niall is First Secretary for The Technical Cooperation Program at the Embassy of Canada in Washington, DC. He graduated from McGill University (Montreal, Canada) with a doctorate in psychology. He pursued postdoctoral studies in the experimental psychology of vision at Queen's University (Kingston, Ontario, Canada) and the Defence and Civil Institute of Environmental Medicine (Toronto, Ontario). He has been a scientist with Defence Research and Development Canada in Toronto since 1988. He was an exchange scientist to the US Air Force Research Laboratory's flight simulation facility in Mesa, Arizona. He has published widely in the study of human vision and visual displays.

“Particularly impressive in all of Schrödinger’s writings presented here is the frank tentative and open approach that he takes. … The work is interesting and valuable to non-experts, such as some artists, who might find the mathematics hard going.” (Ernest Edmonds and Mike Leggett, Leonardo, .leonardo.info, May, 2019)“I find Niall’s translation to be a faithful representation of what I view as Schrödinger’s contributions to colorimetry (both fundamental and advanced). … I stand in awe of Niall’s compendium of translations, each done independently of the earlier ones. The arguments one can have about which translation is more ‘correct’ will be around for a long time and cannot be escaped. For the academician/color-theorist, this book is a must-read.” (Michael H. Brill, Color Research and Application, Vol. 43 (04), August, 2018)​
