About Frank J. Sprague
Frank Julian Sprague was an American inventor who contributed to the development of the electric motor, electric railways, and electric elevators. His contributions were especially important in promoting urban development by increasing the size cities could reasonably attain and by allowing greater concentration of business in commercial sections. He became known as the "father of electric traction". Demonstrating an aptitude for science and mathematics, Sprague secured an appointment to the U.S. Naval Academy in 1874 and, after graduation in 1878 and two years at sea, resigned to pursue his career in electrical engineering.
