Dr. Agar

A revenge-mad scientist who attempts to wreak vengeance on the wealthy men who refused to finance his experiments with shrinking gas by placing his victims inside a gigantic room designed to trick them into believing that they have been reduced to the size of Pygmies so that he can extort large sums of money from them in return for restoring them to normal. Batman and Robin apprehend Dr. Agar in September 1947.
