description Andrew Jackson Beard Overview

Andrew Jackson Beard was an American inventor and farmer born into slavery who made significant contributions to railroad safety. He is best known for patenting the "Jenny Coupler," an automatic railroad-car coupler, in 1897. Motivated by the dangerous nature of manually linking train cars—an occupation in which he suffered a severe leg injury—his mechanism allowed cars to connect automatically, vastly reducing the risk of amputations and fatalities for rail workers.
