So I returned to South Africa in December of that year – it's '54 – with the idea that I would start to work on the genetics of cofactor requirement in order to prepare the way for a full gene protein analysis, and that is something that I could do in South Africa. And so I was extremely depressed when I left America, because at that time I thought: I'll never see it again. You know, that was the end of the… the end of everything. But of course there were already conversations, when I came back to South Africa on the way I went to England, and there I talked to Francis, and there… there we had this discussion on degenerate coding and templates, and there we had the idea that I would come to join them in the Cavendish because we were talking the same language. However, I had to go back to serve my bondage, and all the wheels would be done to try and bring me back as… as soon as possible.
