Facts:
Leonardo Da Vinci may well have been 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, but either he lost interest in building them or was never able to convince one of his wealthy friends to finance construction of his designs. As a result, almost none of da Vinci's inventions were built during his lifetime. And, because he never published his diagrams, nobody else knew about them until his notebooks were discovered long after his death.
That's a pity, because 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.
His most famous inventions:
Da Vinci is most famous now for his inventions: his bicycle, airplane, helicopter, and parachute were all some 500 years ahead of their time. However, he also showed remarkable insight in the world of science. The only remains of this work are his notebooks, now among the most valuable documents in the world. The thousands of surviving pages reveal the most eclectic of minds. He wrote and drew about subjects like geology, anatomy, flight, gravity and optics, often going from subject to subject on a single page in his left-handed mirror writing.
This is his Parachute that he invented.
This is Leonardo Da Vinci.
