I seem to have bragged before about studying with Paul Halmos:

He seemed a bit formal and intimidating at first, but he turned out to be a warm, considerate person. He and his wife had me and several other students over to their house for dinner a couple of times, and he enjoyed talking with us about whatever youthful nerdish topics we were interested in.

I was about twenty years old then. I just realized that he was in his early sixties, a couple of years younger than I am now.

Thanks! Seems like a lovely teacher and person.

Also, interesting to read about the Moore method (I found vid the Algolia link). If I'll ever do some teaching stuff, I'll try Halmos' flavor of that method :-)
