The Nobel Prize is fine, but the drugs I've developed are rewards in themselves.

Nobody . . . took me seriously. They wondered why in the world I wanted to be a chemist when no women were doing that. The world was not waiting for me.

Don't be afraid of hard work. Nothing worthwhile comes easily. Don't let others discourage you or tell you that you can't do it. In my day I was told women didn't go into chemistry. I saw no reason why we couldn't.

I think it's a very valuable thing for a doctor to learn how to do research, to learn how to approach research, something there isn't time to teach them in medical school. They don't really learn how to approach a problem, and yet diagnosis is a problem; and I think that year spent in research is extremely valuable to them.

I had fallen in love with a young man... and we were planning to get married. And then he died of subacute bacterial endocarditis... Two years later with the advent of penicillin, he would have been saved. It reinforced in my mind the importance of scientific discovery...

That was the turning point. It was as though the signal was there, 'This is the disease you're going to have to work against.' I never really stopped to think about anything else. It was that sudden.
