And so in 1941 I got my MD degree. But by then, of course, it was almost impossible to conduct any sort of research because we couldn't get the chemicals, we couldn't feed the animals and so on, so I was left to... doing library research. But in the meantime there was a problem of getting a job, making a living. '41... I was an MD so what was I going to do? And so I went to see my professor, Bouckaert and I said to him, well, I don't want to become a physician, I want to do research, so I'd like to try and find a job to do research. He said, well, that's quite impossible and I think that's very stupid of you because you will never get a professorship at this university because you are not the son of a professor, you're not the nephew of a bishop and therefore there is no way for you to get a job. I said, but I don't really need to have a job at this university, there are other universities in the world, the war will be over one day and I'm a citizen of the world. Well, that's the way I felt when I was young, with the kind of background I had. And he said, yes well in any case, you can't do that now and I think you should not forget that you have an MD degree and that is probably the way you will be able to earn your living. And so I suggest that you try and take a job at the hospital as an assistant in one of... Well, two jobs were available for... two assistantships were available, one in internal medicine.
