Discovering the Crypto-Jews of Portugal

After five centuries of hiding.

In 1917, a Jewish mining engineer named Samuel Schwartz arrived in northeastern Portugal to work. His local contacts warned him against doing business with the residents of certain villages, as they were Jews and therefore swindlers. A native of Poland, Schwartz was unsurprised by this sort of prejudice, but didn’t expect to find coreligionists in a place where the practice of Judaism had been illegal for five centuries. Henry Abramson tells the story of what Schwartz found. (Video, 7 minutes.)
