The job in Wisconsin was the first genuine offer of an academic job in a university which I received.

I had some hesitations about philosophy because, if you worked out a philosophical theory, it was hard to know whether you were going to be able to prove it or whether other theories had just as good a claim on belief.

I don't think Post often came to Princeton during the '30s. I can't remember ever seeing him in Princeton.

I went to Princeton in the fall of 1930 as a half-time instructor.

It wasn't until my second year that I got to actually work with Church.

Here at Wisconsin we didn't get an undergraduate course in mathematical logic until the '60s.

I read one or two other books which gave me a background in mathematics other than logic.
