My father was a great educator for me. He taught me so many things. He named me Carlos after a brother he lost — a very brilliant young man who died at 21 in Mexico. He had written very good poems. He was an intellectual. I think my father wanted to see his brother in me, so he put books into my hands at a very early age. He fostered my literary and artistic inclinations. So he was my best teacher.

They were local. They tended to be the math teacher at junior high school, Jack Druckman, the math teacher in high school, Irene Finkel, who ran and supported the math team. They tended to be very local heroes. I was never one at those times for distant heroes and truly heroic legendary heroes. They were the local teachers who really made a huge difference in my life.

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.

One in particular, Mrs. Gordon. I hated her. I took AP English. The AP courses were just starting in the ’50s. And you could take a maximum of two. I took Chemistry and AP English. Today, the kids come into Duke, they have ten, 12, 15 AP courses. They start taking AP courses in their first year of high school. It’s absolutely amazing. Mrs. Gordon taught AP English. And she took a disliking to me for some reason early on, and she didn’t like the way I wrote, so she gave me very bad grades on all my essays. She pounded into me about how to write clear, effective, succinct English. And I learned those lessons well. But what I remember — and I pay her a tremendous tribute for that because there’s no more important skill, certainly for a scientist, but really for almost any profession, than to be able to express yourself clearly and succinctly. And I think she really taught me that.

That's all I was: a teacher. That's all I was as a basketball coach, just a teacher.

They become almost like your children. Next to your own flesh and blood, you get very close to them. Their joys are your joys, their sorrows are your sorrows and that goes on forever. It doesn't end when they leave your supervision. That's with you forever.
