My boss, the publisher of David Magazine, has this wonderful way of working. If I happen to be traveling somewhere, he knows something about the history and sends me on an adventure to write a story for an upcoming issue. This time, I was in Portugal, so he sent me in search of Portuguese Jewish history. The result is at the link below. Enjoy!
