W. Ross Ashby
in Black box
William Ross Ashby (1903–1972), British psychiatrist and a founder of cybernetics. Director of Research at Barnwood House Hospital in Gloucester when An Introduction to Cybernetics appeared, and later at the Biological Computer Laboratory at the University of Illinois. He is known for Design for a Brain (1952) and the Law of Requisite Variety; his work for this topic is the chapter that gave the black-box method its general statement.

Ideological and professional. Ashby was building cybernetics as one science across brain, organism, and machine, and the generality of the black-box method was central to that programme. The monograph had no commercial dimension.
In the chapter "The Black Box," Ashby took a problem from wartime electrical engineering — deduce a sealed unit's contents from what its inputs do to its outputs — and argued that it generalises to any system closed to inspection, the brain included. The symmetry the modern debate turns on is already his: he runs the method over a circuit and over a brain-damaged patient in the same pages. The term returns, with its secrecy sense foregrounded, in Pasquale's The Black Box Society; the method itself — inferring function from input and output without opening the case — is what Jonas and Kording later run on a chip whose wiring is fully known.
