Why Famous: Prolific inventor whose discoveries changed the modern way of life. His inventions included the phonograph, the electric light bulb, the electric power industry, and motion pictures. His passion for direct current (DC) over Westinghouse's alternating current (AC) resulted in the shameful electrocution of both an elephant and a man.
