Who first discovered CMYK?

Question

It has been used for colour printing for many, many years, but who (and when) first discovered that a bright pink colour (magenta), a light blue (cyan), yellow and black can be mixed to create almost all colours? How did they discover this?(Or more correctly "CMY" - the Black (K) isn't strictly necessary)

Answer 1

I can't vouch for its veracity, but I did find this link:
