I don’t know Don, I’m sure he’s a fine guy, but I’ve read about all these kinds of rules (EDIT: emerging) much earlier - as early as 1940s, with airplanes and cars and other machines in production and in front lines that people had to operate for long hours under strain and make as few mistakes as possible.
Even USSR, not the Rome of ergonomics, had GOSTs for average ratio of errors an operator makes on a certain machine, machines had to be inside those numbers in tests involving people, or they wouldn’t get adopted into wide usage.
Note how the criterion is defined. Not formalities like the shape of something or the layout conforming to some vague definition, but the results of an actual test on people. Of course, though, there were also a myriad GOSTs as to how the specific controls may look, a GOST for every detail one could use in a device.
