Kees van Prooijen
Kees van Prooijen is a microtonal theorist who is noted for inventing the Kees height, the "expressibility" measure for the complexity of just intonation pitch classes, as well as discovering the Bohlen-Pierce scale in 1978, independently from Heinz Bohlen who discovered it in 1972 and from John R. Pierce who discovered it in 1984.
