I would have liked to be a Member of the Society of Fellows at Harvard, but that didn't work, they didn't accept me. And then there was another thing that Viki tried and that didn't work either. I forget what that was. So then, he tried the Institute for Advanced Study and there I was accepted. But then I delayed writing up the dissertation. I should have written it up by June 1950, which would be two academic years of work, because I'd done most of the work, I just had to write up the dissertation. But I've always had this terrible, terrible problem since I was a little boy of writing things up. And I delayed and Viki left for France where he was a visiting professor that year, and, I stayed around MIT. And then something else happened that was bad. The assistantship had been replaced by an AEC scholarship, the Atomic Energy Commission scholarship. I got one the very first year they were offered, and that covered everything, so I didn't need to be an assistant any more. The scholarship was very good. But, then, it was discovered that one of these scholarships had gone to a Communist. To the Senate the idea of associating AEC, Atomic Energy Commission, with Communism was just too much to bear. So they passed the O'Mahoney amendment, named after Senator O'Mahoney of Wyoming, I believe, which required a full AEC clearance for anyone who had an AEC scholarship. Well, that of course stopped the payments on my scholarship until I could get an AEC clearance, which dragged on and on and on and on. So, I had no money and I hadn't finished the dissertation and I was paralysed. I just somehow couldn't work on it. And I sat around reading 'The Tibetan Book Of The Dead' in Evans-Wentz's translation in twelve volumes from the graduate house library, and things like that. And living clandestinely in the graduate house as the guest of my former room-mates and other people. I made some wonderful friends that way, actually. These new, there were some new room-mates whom I got to know - two European graduate students. This is 1951? This was, no, this was 1950. So you'd basically done your dissertation in two years? In two years. So I should have... And in 1951 ...graduated in June 1950... 1950, but you stayed and then went... ...at the age of twenty. Twenty, exactly? But I stayed on over the summer and into the fall, living in this hand-to-mouth way. And then my friends started to lend me money because I didn't have any cash. So I formed this investment syndicate, people investing in me, and I was able to eat that way. And I lived rent-free as a clandestine room mate, an extra room mate and so on and so on. Finally, New Years Eve came, and I just felt I just couldn't go on this way any more. The Institute for Advanced Study kept calling and saying, "When are you coming? What's going on here? Are you a ringer? Do you really exist?" And, so finally on New Years Eve I drank quite a lot and started to write the dissertation, and within a few days I had it written and I had the exam and got the PhD in January 1951. And then I went to Washington, I was invited to Washington for a clearance interview, and we thrashed out what was worrying them about my former left-wing ideas and contacts - which were minimal - and everything was all right. I got the clearance, they paid me my back-pay. I had pay now from the Institute for Advanced Study where I went promptly. So I had money; I was able to pay back all my friends, which I'm not sure they expected; and I was able to buy a car. So I was at the Institute for Advanced Study; I had my PhD, I had a car, I had enough money to live on, I'd paid back my debts - everything was very good.
