:Thanks Tritomex for initiating a discussion about this. Unfortunately, it was not me who introduced the above statement and I do not have access to the aforementioned book (nor to the other reference: "Dangerous Diplomacy: The Story of Carl Lutz" by Theo Tschuy). We may try to look up the user(s) who introduced that information (it should be in the history) and ask him (them). I will also try to look up some sources about this, if I find some time for that.
