- Thomas Seavey Hall (born Thomas Shepard Hall / April 1, 1827 – December 1, 1880) was an American textile businessman. He invented accident prevention signal devices for the American railroad and transportation systems. His most popular "banjo signal" was used on many New England railroad systems for decades and increased speed and safety. Hall patented many of his signal devices, and other railroads later developed signals based on his systems. Hall was inducted into National Inventors Hall of Fame in 2007 for his improvements in electrical signals for the American railroad system. (en)
