Hitler's Secret Bankers was the first book to disclose the extensive collaboration among Swiss banks, the Swiss government, and the Third Reich before and during World War II. Switzerland, supposedly neutral in the war, seemed a safe haven to desperate Jews who entrusted their wealth to its banks, believing that even if they died their families would inherit it. For more than fifty years, this money has provided free working capital for the banks. In addition to the dispute over dormant accounts, Swiss banks provided the Nazi war machine with foreign currency, which paid for vital war materiel such as chrome and aluminum.
