I haven’t grown up.

I really had no idea whatsoever. I feel that my life developed as I went along. I was never one of those people who, at an early age, had picked an objective and worked steadily towards it. All I knew was that I wanted to get involved in adventurous activity. I didn’t have any specific type of activity in mind, but I wanted to do things that were exciting and adventurous. I had a fairly diffused feeling as to what precisely it should be.

Archaeologist, pop star, store cashier.

A nurse, because my grandmother was a midwife. I was named after her but never got to meet her.

Certainly not. As a young child, I remember just dreaming about the Nobel Prize, but that was just a dream. It’s not something I would have ever thought was possible for me.

In terms of this issue of these industrial gases affecting the environment, at the beginning the road was not easy, because we were suggesting that society had to change, that industries had to do something different than they were doing at that time. And of course, initially we did not meet with a good reception to these ideas from industry. And even from the scientific community — even though our ideas were well received in the small group of specialists in what we were doing — it was not necessarily well received by the scientific community at large. So we really had to continue doing as good a science as we could, and at the same time trying to well communicate our conviction that it was something important, something that had to change in the way society was functioning.

Although my years at Irvine were very productive, I missed not doing experiments myself because of the many responsibilities associated with a faculty position: teaching courses, supervising graduate students, meetings, etc. After spending seven years at Irvine as Assistant and then Associate Professor, I decided to move to a non-academic position. I joined the Molecular Physics and Chemistry Section at the Jet Propulsion Laboratory in 1982. I had a smaller group – only a few postdoctoral fellows – but I also had the luxury of conducting experiments with my own hands, which I enjoyed very much.

As I was starting my academic career, it was almost considered to be a negative signal to your career to get involved in politics ... But to me that was a sign you were doing something useful.

It was probably a series of biographies of scientists like Pasteur, or even earlier ones — Leeuwenhoek inventing the microscope and Madame Curie. I forget how many others, but it was really just, for me, a fascination to learn about these great heroes. At that time, of course, they were totally inaccessible, almost non-human, to me. It became very interesting to me.

At first the research did not seem to be particularly interesting – I carried out a systematic search for processes that might destroy the CFCs in the lower atmosphere, but nothing appeared to affect them. We knew, however, that they would eventually drift to sufficiently high altitudes to be destroyed by solar radiation. The question was not only what destroys them, but more importantly, what the consequences are.
