What Jan Koenderink wrote below, is also true for me! 😎
Now and then I become so much interested in a person’s work that I really want to know more. I then read all I can dig up – the science, the reactions of contemporaries, and the bits and pieces that might give me glimpses of personal life. The last occasion this happened to me concerned Ostwald. It turned out to be an often surprising, thus very entertaining, and also rewarding exercise.
