Thanks, seeing it in the article was a surprise to me. Many Germans and European Jews found their way to Brazil, Argentina and Chile after WWII, for different reasons, obviously.
Most of the Jewish population in Latin America (as is the case in North America) is Ashkenazic. Although Argentina, Brazil, and Cuba had sizeable waves of Russian, Polish, and German Jews in the second half of the 19th/early 20th century, you are very much correct in the large number of refugees from Hitler's Germany that found their way from Sinaloa to Santiago. My former professor found himself fleeing Austria to London and then to Mexico City after the Anschluss.
The exception in Latin America is Panama, where Sephardi Jews from Syria dominate the community. The came after WWII to set up textile firms in the Colon Free Zone. Many of these folks were my clients when I was a young commercial lender all those years ago.
