A couple of years ago my dad emailed me and my brother: I very well understand that I am quite an ordinary person, similar to billions of others who lived on this planet before me and some more billions who will follow. As such there is no need for me or for anyone else to write my (hi)story. But just in case you want to know about me some time later… I do not know many such things about my father. Hence these details. I might have told you some of these in bits and pieces but never systematically.
