Then you have the clients. The care and feeding of clients is really one of the main obstacles, because you always have a client with some preconceived idea of what a house looks like, and all you want him to do is leave a check and go to Europe for a couple of years. Or leave two checks. But alas, life isn’t simple. If it were, more people would be better architects.

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.

At Pixar when we were making Toy Story, there came a time when we were forced to admit that the story wasn't great. It just wasn't great. We stopped production for five months.... We paid them all to twiddle their thumbs while the team perfected the story into what became Toy Story. And if they hadn't had the courage to stop, there would have never been a Toy Story the way it is, and there probably would have never been a Pixar.

But, of course, we had one problem that the modern mountaineer doesn’t have. That is, this psychological barrier. We really didn’t know whether it was humanly possible to reach the top of Mt. Everest. And even using oxygen as we were, if we did get to the top, we weren’t at all sure whether we wouldn’t drop dead or something of that nature. All the physiologists had warned us that the altitude at the summit of Everest was a very marginal altitude and might be extremely dangerous. So, one had this feeling in your mind all the time that maybe you were pushing things a bit beyond what humans were meant to do and you couldn’t ignore that feeling. But, because of strong motivation, you keep plugging on and you seem to be going okay and nothing seems to be going wrong, so you persist. And we persisted, of course, and ultimately, set foot on the summit.

Professor Randall was a great advisor and a great mentor. He taught me, I think, in the best possible way. He was not a brilliant lecturer. His courses were fairly pedestrian. I didn’t think his seminars were particularly interesting. But working with him on a one-to-one basis as his assistant, I think that’s the way one has to learn to be a historian. That is, he was writing, and if he needed some particular reference, I had to go find it and get it. If he was writing, he wanted everything checked meticulously over and over again. So I had to take the manuscript over to the library and check it all out. So that by working closely with him, I got to see, first of all, a lot of the library and its extensive holdings, but I got, even more important, to understand what a scholar is about. It is about care. It is about “pains-taking.” It is about judgment as well as it’s about very skillful writing. He was an excellent writer as well. So in that sense, Professor Randall and Mrs. Randall shaped my future career.
