* World War II led to an explosion of new technologies that would have profound effects in the postwar period. Although advanced Nazi aircraft, guided weapons, and long-range rockets are well known, in reality the Allies led the Germans in many fields, and not only had more resources to draw from but were much better organized to exploit their new inventions. The atomic bomb is the most spectacular example of Allied technical superiority, but just as significantly, the Allies developed radar and other new "electronic warfare" technologies at a rate that left the Axis in the dust. Winston Churchill called the race for electronic superiority the "Wizard War". This document provides a history of the Wizard War.
