Pelley was a successful writer and journalist who became a maniacal anti-communist and anti-Semite after spending some time in Russia during the formation of the Soviet Union. In the 1930s, he developed a fiery hate for President Franklin D. Roosevelt because of his destructive socialist initiatives, like offering millions of people aid to keep them from starving to death during the Dust Bowl. Thanks, Roosevelt.
But instead of trying to assassinate the president (which would have gone well with his three-names vibe), Pelley got into politics to counteract this growing communist influence in the United States. He started a fascist organization/cult called the Silver Legion, which is as close to the Legion of Doom as America has yet come. The Silver Legion was inspired by Hitler's Brownshirt militia, and dressed like space-age Mormon missionaries with scarlet Ls on their chests. Really. As their leader, Pelley also began publishing a newsletter which quickly became known as "the most racist publication in the United States" -- which was quite a feat for the 1930s.
