An unknown story of an unlikely hero - the US consul who best analyzed the threat posed by Nazi Germany and predicted the horrors to come.

In 1929, Raymond Geist went to Berlin as a consul, and he handled visas for emigrants to the US. Geist expedited the exit of Albert Einstein just before Hitler came to power. Once the Nazis began to oppress Jews and others, Geist's role became vitally important. It was Geist who extricated Sigmund Freud from Vienna and Geist who understood the scale and urgency of the humanitarian crisis.

Even while hiding his homosexual relationship with a German, Geist fearlessly challenged the Nazi police state whenever it abused Americans in Germany or threatened US interests. He made greater use of a restrictive US immigration quota and secured visas for hundreds of unaccompanied children. All the while, he maintained a working relationship with high Nazi officials such as Himmler, Heydrich, and Göring.

While US ambassadors and consuls general cycled in and out, the indispensable Geist remained in Berlin for a decade. An invaluable analyst and problem solver, he was the first American official to warn that what lay ahead for Germany's Jews was what later would become known as the Holocaust.
