In the evenings I studied chemistry at the University of Chicago, the weekends I helped in the family store.

I joined the Army and was sent to the MIT radiation laboratory after a few months of introduction to electromagnetic wave theory in a special course, given for Army personnel at the University of Chicago.

I studied chemical engineering. I was a good student, but these were the hard times of the depression, my scholarship came to an end, and it was necessary to work to supplement the family income.

If you've never met a student from the University of Chicago, I'll describe him to you. If you give him a glass of water, he says, "This is a glass of water. But is it a glass of water? And if it is a glass of water, why is it a glass of water?" And eventually he dies of thirst.

In 1933, the Nazis came to power and the more systematic persecution of the Jews followed quickly. Laws were enacted which excluded Jewish children from higher education in public schools.

I feel I learned as much from fellow students as from the professors.
