John Nystrom’s “A New System of Arithmetic and Metrology, called the Tonal System”1 (1863) is a very early entry in the history of the application of the hexadecimal system. Nystrom’s plan included converting to a hex arithmetical system, and then expanded the idea to the calendar, musical notation, geography, time—an overall shift in metrology. His idea did not extend to calculators, and his name does not seem to be referenced by any of the modern compsci folks (with the major exception of Donald Knuth). Probably base-16 was not employed in programming until, I guess, around the early 1960’s. All that said, this is still a remarkable paper. ALSO: the paper is illustrated with a beautiful color-highlighted folding plate of divider-like instruments that translated hex to denary.
