The music of the “I Have a Dream” speech is a replication of the music which comes out of the mouths of the African American preacher. Preacher, singer, blues singer, jazz singer, rap person, it is so catching, so hypnotic, so wonderful that, as a poet, I continue to try to catch it, to catch the music.

That’s an easy question. It was, of course, George Balanchine. He came from Russia via Europe and settled in America in 1933. He started a little company which was not very successful, so he had to start over and over again. Ultimately, he founded the New York City Ballet. I happened to be born at the right time, came to the right place, and had the fortune to audition for him, and work with him, because he is the genius of the century of ballet. I learned how to dance with him.

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.

It was a very important finding for us because we were involved in nucleic acids. There weren’t many people interested in nucleic acids. There weren’t many people who believed that was the way to find drugs. But when we found out the structure, and we began to understand what kind of bases could be incorporated, and which ones couldn’t, and where they could be incorporated, it put a whole new dimension on it. So it had a very significant effect.

It can be combining something disparate. With Greenberg , for example, I had the idea with the character and I wanted to make a movie in L.A. and about L.A. Then I put the two things together and that was the movie. With Francis Ha I wanted to do things in black and white, in New York, and with Greta Gerwig. These are the more conscious things.
