Well, naturally, my grandfather. He was a Hasid, meaning a member of the Hasidic community, and I loved him, I adored him. So thanks to him, I became a Hasid too. And my mother — who actually continued his tradition — she’s the one who brought me to Hasidic Masters. And all the stories I tell now — I’ve written so many books with Hasidic tales — these are not mine, these are theirs, my mother’s and my grandfather’s. My father taught me how to reason, how to reach my mind. My soul belonged to my grandfather and my mother. They enriched me, of course. They influenced me profoundly, to this day. When I write, I have the feeling, literally, physically, that one of them is behind my back, looking over my shoulder and reading what I’m writing. I’m terribly afraid of their judgment.

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.

One was Roscoe Gilkey Dickinson. He had got his doctorate in physical chemistry — x-ray crystallography — in 1920. He was the first person to get a Ph.D. from California Institute of Technology. And he was continuing with x-ray crystallography, determining the structure of inorganic crystals. After I had accepted appointment as a graduate student at California Institute of Technology, A.A. Noyes, the head of the division of chemistry and chemical engineering, wrote to say that he had decided I should work with Roscoe Dickinson on determining the structure of crystals. This was really extremely fortunate for me, in my opinion. I don’t think that there was any field that was more suited to my interests, and I don’t really know why Dr. Noyes selected me out of eight or ten new graduate students to do x-ray crystallography. Dickinson had a remarkable mind. He was a very careful investigator and thinker, a very logical thinker. When he was teaching me x-ray crystallography, he also taught me to ask at each stage in the argument, “What assumptions are being made? How reliable is the conclusion that you draw? What chance is there that one of the assumptions you have made is not correct?” “You should recognize,” he said to me, “that there is in almost every investigation a lack of complete rigor. You should understand just how reliable the arguments are that you are presenting.

No. Although I have to qualify that. Though he was, by jazz standards, a very square composer, he was, by musical theater standards, a not square composer, and he taught me to be less square. I tend to be square.

It comes out of an intuition, or a learned intuition, I guess. You study a long time ’til you can do it. But it’s from looking around you, it’s from understanding what’s happening in the culture, what’s happening in the world.
