| Jul 1, 2021 at 14:48 | comment | added | John Coleman | Ideas from clone theory go back to Post's classification of clones on 2-element sets back in the 1940s. It is an anachronism to describe this as clone theory in the modern sense, but it pushes back some of the ideas to well before Cohn. | |

This kind of history will never get written up. Your best bet is to have a private conversation with the senior people that you know. | |
