In 1913, the noted German actor and director Paul Wegener was making a film in Prague when he heard the legend of Rabbi Loew, who created a golem to protect the inhabitants of the Prague ghetto from persecution.

According to Jewish legend, only the very wisest and very holiest rabbis had the power to make golems, animated servants of clay. Strictly speaking, the golem is not in the same class with Frankenstein’s monster, because the golem is neither alive nor dead. He is, rather, the ancestor of all robots.
