Born: April 4, 1826, Yehe Bodegne Died January 20, 1901. Bois-Colombes. Belgian electrical engineer. In 1856, he joined an electrical equipment factory in Paris, where he invented and improved various electrical devices. In 1869, he invented the direct current generator, and in 1871 presented a prototype (the Gram Dynamo) to the French Academy of Sciences. He later established a generator manufacturing factory. During a demonstration of the Gram Dynamo at the Vienna World's Fair in 1873, he famously discovered by chance that the generator could also function as an electric motor. He made a significant contribution to the subsequent development of the electrical industry. Grams |
