So it’s right in the middle of the Society of Fellows’ three years that I switched from… from neurology to cognitive psychology. And then when the… that Fellowship is up, I’ve made friends with this wonderful Oliver Selfridge who… whose work I first discovered in the Rashevsky book, and it turned out that he was still around, rather same age as me, and had a laboratory at Lincoln and was working on moderately interesting questions like… at that time most communication was with Morse code, and in order to understand Morse code you had people who had to listen and type, and there was no machine that could transcribe hand-keyed Morse code, because in fact if you looked at the data, some of the dots were longer than some of the dashes. So it was all pretty hard problem, and Selfridge had a group that was doing about five things like that, because Lincoln lab was a military… military electronics laboratory that was mainly concerned with making automatic radar systems to catch Russian missiles going over the North Pole, and that sort of thing.

But his group was doing advanced cybernetics and what was just beginning to be called Artificial Intelligence at that time, and Oliver Selfridge was full of wonderful low level ideas about AI and… a very dramatically inventive guy, and very good at collecting people, so he had this group of wonderful young people and… working on… on radar related things.
