When Daniel z”l was kidnapped, Prof. Pearl was desperately trying to get everything taken off the web about himself and their family so that the captures wouldn’t know that Daniel was Jewish, and his parents Israeli.
I had no idea about that, either. Professor Pearl has for so long been a leader in the probabilistic-reasoning field. I first began reading his work 20+ years ago, and was late to the game even then. It appears that he and the rest of his family have been embodying the values much of the rest of the world aspires to, or chooses, for whatever reason, to ignore.
