As individuals, the heads of our Federal regulatory commissions seldom stand before the public, and yet there are no officials of more importance to American industry. Protected in their tenure and clothed with broad discretion under statutory authority, these officials wield power that may mean the life or death of railroads, public utilities, water power companies, and a great host of industries engaged in interstate and foreign commerce. E. Pendleton Herring’s book discloses the salient facts about those who have served on the most important administrative commissions, such as the Interstate Commerce Commission, the Federal Reserve Board, the United States Tariff Commission, the Federal Trade Commission, and the Securities and Exchange Commission. The Civil Service Commission is the only one omitted. The book is thus of immediate service not only to students of government but to all higher executives in American business.
