As far as i know the modern form of null move was invented by the Russian Caissa team (Donskoy, Alazarov, Adelson-Velskiy etc) in the early 1970s. These guys were not commercial. By the late 1970s several British programmers had heard about it and it was probably Don Beal (who is not commercial as far as i know) who made it well known, sometime in the 1980s.
