How important was Catharina M. Koopman to Simon Van Der Meer?

Answer 1

Here is some information on catharina m koopman from an interview with simon van der meer, the nobel peace prize winner in physics; "In the meantime, in 1966, while skiing with friends in the Swiss mountains, I met my wife-to-be Catharina M. Koopman and after a very brief interval we decided to marry. This was certainly one of the best decisions I ever made; my life has since been far more interesting and colourful. We have two children: Esther (1968) and Mathijs (1970)."
That was the only reference to his wife I was able to find that was in english. The rest were in german or dutch languange
