At Asilomar, where I gave a talk — and again the recording of the talk exists there — I had in fact suggested something called the Book of Man. You have to realise that at that time we still did not know that genes contained introns. And what I'd thought was we would take all the genes and we would glue them down on a page of nitrocellulose and this would be the Book of Man and you could turn to page 48, line 23, word four, and there you'd have the gene for serum albumin written there. And so the concept that one could just get the genes by working with DNA was of course very much alive and of course being in Cambridge where Fred Sanger was sequencing DNA, realised that this is on the threshold of the new genetics. And the new genetics is then what I became extremely interested in.
