This is the story of how a beloved German children's book illustrator, while serving in the army of Nazi Germany, saved the lives of hundreds of Jews from Adolf Hitler's death machine. It's ... a story that the artist, [Werner Klemke,] who died 20 years ago, never told. The story surfaced only when Dutch documentary filmmaker Annet Betsalel asked whether she could poke around in the long-shuttered archives of the Jewish community of Bussum, the Netherlands. What she found was the story of a network set up by a Jewish businessman, Sam van Perlstein, who knew in 1942 that Jews were living on borrowed time under Nazi occupation and that if they were going to survive they were going to need some help. Betsalel is turning [the story] into a documentary titled Rendezvous at Erasmus." To survive the Nazis, van Perlstein needed documents proving he was half Aryan, and he asked [a young German soldier named Johannes Gerhardt, his friend] for help. Gerhardt was a photographer and knew he could help with part of the project, but he'd need another friend to produce the documents themselves. He turned to another another German soldier, Klemke, who ... hated Nazis, and was an artist. The documents they created were perfect, and fooled everyone who needed to be fooled. They allowed van Perlstein to reclaim his import business and money that had been frozen. That money went to fund resistance to the Nazis, and a hideaway network. Over the next few years, [Klemke] produced documents that helped some people escape from the country, and allowed others to survive while they remained in hiding.
