Whatever the case, in '47 my uncle thought of it, not because it was, how to say, intellectually challenging but because it was mathematically difficult, and because Julia and Fatou had stopped at the point and couldn't go any further. He gave me the original reprints of Fatou and Julia to read, and I still own the one of Fatou which was an off-print with renumbered pages, one to whatever, two hundred and seventy-five, a combination of three papers, a little book which is a very valuable item, which Fatou had given to him one time. I don't know what happened to the Julia reprint, so I used the Julia collected works as a reference. For me reading the Fatou-Julia was very easy because in a way I was a trained mathematician - I was so under-trained in terms of going to school, and anyhow the school then was very old-fashioned and Paul Levy was so old-fashioned, and I had been reading Paul Levy, so reading Julia and Fatou was not a pain. For many other people it became very difficult. They wrote beautiful sentences in French, where it was not clear, separate. which were the conditions, which were the conclusions. Sometimes it would say it could not be wrong data - and in fact sometimes the argument would be simple and sometimes very difficult. This was mathematics before the great formalisation of later periods. They also sometimes made mistakes, which were forgiven by their time but not forgiven later in their work. Whatever the case, in 1947 or so I read these papers, I studied them and first of all I did not appreciate the contact with anything physical, which for me was so important, and I did not at all appreciate why these things were particularly interesting. And Julia by that time - Fatou already had been long dead, Julia was still alive, he lived to be very old - was he was very much outside of the great men of the times. He was viewed as being old-fashioned, someone who had done something important in the past but well forgotten. So that's chapter one.
