After the Fellowship I spent a year with Selfridge, or maybe two.

[Q] Yes, at Lincoln?

At Lincoln, and then I got a letter from the math department saying: 'Why don’t you be a professor here?' So then I moved to MIT and I taught calculus for a year or two.  And I found that rather tedious, teaching these things, because I would prepare the lectures and then, you know, you had to give two courses every two days, and so I’d spend half the time in between figuring out what I did wrong, and the other half planning the next one and… that went on a couple of years. I had this big group growing and functioning, and then one day I ran into Peter Elias, who was head of the EE department, temporarily. He said: 'How are things going?' And I said: 'Oh, it's… I’m not having enough time to do research'. And he said: 'Well, why don’t you move over to the EE [Department of Electrical Engineering] department, because we have lots of money, unlike the math department, so we only have to teach two courses instead of four'. And then it turned out that for some reason… then I got some money from ARPA – some extra money – and then it turned out I only had to teach two courses every other term. And then one of those disappeared, so now I was teaching one… one course half the year.
