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 remember Nazi election propaganda posters showing a hateful Jewish face with crooked nose.

I survived only a year in Berkeley, partly because I declined to sign the anticommunist loyalty oath.

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.

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.
