The "Brain Trust" or "Brains Trust" was the name given to a diverse group of economists, professors, and others who served as advisors to U.S. President Franklin D. Roosevelt during the early period of his tenure. These men played a key role in shaping the policies of the First New Deal. Although they never met together as a group, they each had Roosevelt's ear. Many newspaper editorials and editorial cartoons ridiculed them as impractical idealists. Wikipedia
