Stanislaw Lem is not widely known in America, but he is one of the most influential and beloved science fiction authors of all time. His most popular topic was robots, his most famous work was "Solaris". (Oh, so you heard of this one?)

Lem was Polish: he was born in Lwow, in what was then Poland, and lived most of his life in Krakow. He wrote in Polish, is adored in Poland...

You know where this is going. Although Lem, like most of Poland, was raised Catholic, he was, in fact, ethnically Jewish. Being Catholic did help him survive the War, as did falsified papers that hid his Jewish ancestry. (This is the rare case where we don't frown at conversions.)

Heck, we're gonna go as far as assign Lem one of the highest Jew Scores for someone who wasn't technically Jewish. Although, a nerdy science fiction author, writing about robots and loneliness? Perhaps he was more Jewish than he let on...
