I did have — definitely — one heroic figure who impressed me very much indeed, and that was the great Antarctic explorer, Shackleton. Shackleton I always admired because he was a tough man and a very good leader. And whenever he was in difficult circumstances, which he frequently was, he seemed to have the great ability to inspire his men and lead his party safely out of those conditions. So certainly Shackleton, I would have said, more than anything, was a role model for me.

My parents were both physicians. The family physician type, not fancy researchers or anything like that. I picked up a sense of this idea that you do serve, you serve people actually. It’s an interesting thing. I don’t think they ever said that in any explicit term, but you could just see in terms of how — individual patients weren’t discussed — but just certain things were discussed, and you could see that that was important that you were doing something bigger than yourself. You were doing something for society. For some reason I was able to pick up on that, so I think that influenced. Especially my mother, who was a physician, who spent a lot of her hours in the office talking to her patients, and she would say talking was so important for many of her patients. Sometimes there weren’t even obvious things that a physician could do something about, but she said it meant a lot to them.

He was a little guy who was a great football player at Georgia Tech, and he just was indefatigable. He just would never, ever say die. He absolutely proved to me that persistence was a very big part of making it in life. I never forgot that lesson.

Yes, there were. In kindergarten, there was a teacher named Miss Shackleford, as I always called her. I honestly cannot remember her first name, although I saw her years later. She took a special interest in me very early, which made me feel very special. Maybe I can really do things with these words, and so on, and ended up combining my kindergarten and first grade into one year. Which I don’t really advocate, because you end up being smaller, a year younger than the people you’re competing with. But anyway, she got me off to a good start.

Yes, that’s right. I saw what I could succeed in. I never considered myself very bright, and I always thought of myself as mathematically mediocre. So I figured that probably, like your college runner who has difficulty breaking a ten-second hundred — well, breaking an 11-second, shall we say, 100-meter — realizes that their best shot is to rely less on strength and speed and more on self-discipline, planning, and long hard work. Yes. That’s the way I do science.
