Audio Clip — McCraw on Tedlow
That is to say if Richard Tedlow goes in to teach—and he’s maybe the best classroom performer in the history of the School—he has taught, first, marketing. He knows the curriculum. He knows something about finance. He’s the biographer of Andy Grove, so he knows something about technology. And he also knows the students. He spends—I think he’s got every class card of every student he ever taught in every class in the world.
So Richard is an extreme example of something that I did, and that Nancy did, so that for about ten years, the three of us would—two out of the three of us—would teach this course every year. And all three of us were star teachers, and we could draw 200 people. If we had been less good teachers, say B+ teachers, I think the number would have been 250, rather than 400.
