37. John Sherman
John Sherman was the brother of General William Tecumseh Sherman and a noted politician from Ohio who served in the House of Representatives, the Senate, and as Secretary of the Treasury. He was instrumental in the reform of coinage as well as civil service reform and upon his return to the Senate he supported the Interstate Commerce Act, which helped restrict extortionate rates charged by some railroads due to a lack of competition. His most famous achievement was the Sherman Antitrust Act, which serves to maintain competition in the marketplace for the protection of consumers, and which remains in effect in the 21st century.
