There was no physician in my family. There were a number of chemists and engineers among my German family. Some of my cousins occupied rather important positions in the chemical industry in Germany, in the IG-Farbenindustrie, the Bayer Nobel factories in Germany. So, I... I had contacts with that side but not, not in my Belgian family, not that I can think of at all. No, they were all rather... rather... either... either, you know, interested in the humanities or even in culture. I had an aunt who was a very good marine painter, sister of my father. Her husband was a composer who had been the director of the conservatory, the music school in Antwerp who played the organ in the cathedral and composed, even, an opera that was played every year in the Antwerp opera. Another uncle was a sculptor and so on, so we were rather a cultured family but not at all interested in science. My father's main interest was the French language. He was a stickler for grammatical precision, for good structure and so on, he was very strict also about manners and things of that kind but science, no, nobody talked about science.
