In addition to the research, I enjoyed learning French and assimilating the culture of another country.

One of the greatest joys in my life was giving a lecture in French at the College de France.

On even the worst days, when nothing was working at the lab, I knew that at home I would find warmth, peace, companionship, and encouragement. As a consequence, the next day would surely be better.

Our whole family assembles in Chicago at Christmas and usually in Aspen in the summer.

People don't realize how many aspects of our lives are touched in one way or another by not just the discoveries, the technological breakthroughs, but the process of science.

I crave and seek a natural explanation of all phenomena upon this earth, but the word 'natural' to me implies more than mere chemistry and physics. The birth of a baby and the blooming of a flower are natural events, but the laboratory methods forever fail to give us the key to the secret of either.

My first undertaking in the way of scientific experiment was in the field of economics and psychology.

Sometimes we fall in love with somebody who will probably never love us, for reasons having nothing to do with us but with their own mindset, their chemistry.
