Learned Hand
Chief Judge, U.S. Court of Appeals for the Second Circuit
1872 - 1961
Most influential federal judge never to serve on the Supreme Court, creator of the Hand Formula for negligence and a champion of free expression.
Biography
Learned Hand served as a federal judge for over fifty years, including as Chief Judge of the U.S. Court of Appeals for the Second Circuit, often called the most important federal appellate court below the Supreme Court. Despite never being elevated to the Supreme Court—a distinction widely regarded as an oversight—Hand wielded enormous influence over American law.
Hand's most enduring contribution is the Hand Formula, articulated in United States v. Carroll Towing Co. (1947), which defined negligence in terms of a cost-benefit analysis: a party is negligent if the burden of adequate precautions (B) is less than the probability of harm (P) multiplied by the gravity of the resulting injury (L). This formula became the foundation of the economic analysis of tort law.
Beyond torts, Hand made significant contributions to patent law, antitrust law, and free speech. His Spirit of Liberty speech (1944), delivered at a wartime citizenship ceremony in Central Park, is one of the most quoted addresses in American legal history. Hand was also a key figure in the development of copyright law and statutory interpretation.
