The one thing I’ll always hold my head up high about is that 32 years later, it’s been quite a ride – it’s been a pretty pure ride, a pretty honest ride, a pretty straight ride – we haven’t done things for ulterior motives or tried to do things for commercial gains or for this or for that, so I feel pretty proud of all of it.

Yes, I do, and I like to be seen by fans like this. Being a legend for my fans and my family is something I can be proud of, as I had the opportunity to play in World Cups myself, so I knew what the squad were feeling. I have the third highest appearances for Argentina, for whom many very talented footballers have played, so it’s an honour. To me, representing my home country anywhere in the world has been the best feeling.

Oh, hands down, I’m most proud of the people that I’ve trained and the people that have come from my work — I mean from my lab. I think that when I look at these younger people who are now working in their own right, running research laboratories, doing great work, teaching their students, making new discoveries, that’s what I’m proudest of. That legacy of science that stemmed from — originally — just me opening up my shop at Yale University back in 1994.

Mr. Rogers lives on. There’s so many legions of people that grew up with him, and they’re still in a way growing up with him. He, of course, was a minister. ... And the children of the show, in the neighborhood, are his ministry. And what a beautiful thing that is. So I, to this day, when someone says, “What are you most proud to have accomplished?” I am so proud to have been a part of that.

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.

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.

Sherry offered me a list of research options: the one project that intrigued me the most consisted of finding out the environmental fate of certain very inert industrial chemicals – the chlorofluorocarbons (CFCs) – which had been accumulating in the atmosphere and which at that time were thought to have no significant effects on the environment. This project offered me the opportunity to learn a new field – atmospheric chemistry – about which I knew very little; trying to solve a challenging problem appeared to be an excellent way to plunge into a new research area.

I then converted a bathroom, seldom used by the family, into a laboratory and spent hours playing with chemistry sets. With the help of an aunt, Esther Molina, who was a chemist, I continued with more challenging experiments along the lines of those carried out by freshman chemistry students in college.

I had a number of very good teachers in high school, in fact. Some mathematics teachers that perhaps allowed me the freedom to go beyond the normal routine of the class and to explore some more advanced areas. The same thing happened in college. I was able to communicate with a few of my teachers and professors, and go beyond the normal expectations. And then, as I mentioned before, Professor Pimentel, my mentor for graduate studies, was really influential in terms of the influence that he had for me.

I did. As a kid, I liked music. I still like it a lot of course. I used to play the violin. I did contemplate, well, maybe that’s an option. I could become a musician. Somehow my parents got some advice that unless I was willing to spend eight or 10 hours a day just playing the violin that I should just give it up. To me, that was very bad advice because you could of course, get very involved in music without being a musician. Fortunately, even though I gave up eventually playing the violin myself, I never gave up my fondness for music. But if I had a chance again, I would not give it up. I would just do it as a hobby. I think that was just because I did not get the correct advice.
