James Clark McReynolds (1862–1946) was a U.S. Supreme Court Justice renowned for his firm opposition to President Franklin D. Roosevelt’s New Deal programs, aligning with the conservative "Four Horsemen" bloc. His 26-year tenure on the Court saw him author 506 majority opinions and 157 dissents, 93 of which contested New Deal legislation. Known for his strict adherence to laissez-faire economics, McReynolds’s decisions in cases like Meyer v.
Nebraska and Pierce v. Society of Sisters emphasized individual freedoms and states’ rights, while his dissents in Steward Machine Co. v. Davis and Schechter Poultry Corp. v. United States highlighted his resistance to federal economic control. His legacy remains controversial, reflecting both his constitutional rigor and documented prejudice.
