In 1934, the American Jewish charities offered to find homes for 300 German refugee children. We were on the SS Washington, bound for New York, Christmas 1934.

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.

The pretention that some of us are better than others, I don't think is a very good thing. And who is contributing what to our progress in science is not so obvious and many who don't get that Nobel Prize are better than people... than some of us that do get the Nobel Prize. I think we should not be interested in prizes, we should be interested in learning about nature.

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

The problem of transmitting scientific knowledge is a very difficult business.

I reverted easily to my wild state, that is experimentation.

I had no new ideas on the physics we might learn, and I could not compete with the younger generation.
