LEONARDO DA VINCI, 14521519), Italian artist, architect, engineer and scientist .He can be considered the greatest inventor in history, yet he had very little effect on the technology of his time. Da Vinci drew sketches and diagrams of his inventions, which he preserved in his notebooks. He invented fire throwers and missiles, and made an early design for a machine gun. Hundreds of inventions were sketched out in his notebooks tanks, helicopters, bicycles, submarines, hang gliders, pulleys, cranes, bridges, and more.Da Vinci's designs were spectacularly ahead of his time. If they had been built, they might have revolutionized the history of technology, though many of them may have been impossible to build with the tools available in the 15th and 16th centuries. In recent years, however, engineers have begun to construct models of da Vinci's amazing machines and most of them actually work
