Leonardo da Vinci, perhaps the greatest man in history, invented thousands of things including the helicopter, tank and portable bridge. Leonardo was not only an inventor ,but a sculptor, an artist and an architect. He was born 1452 in the small town of Vinci ,in Tuscany. His father was a wealthy notary and his mother a peasant woman. In the mid 1460s the family moved to Florence here he was given the best education Florence could offer. He advanced rapidly socially and intellectually . He was very handsome and a fine musician.
About 1482 Leonardo entered the service of the duke of Milan. Due to a recommendation stating that he could build portable bridges and knew techniques in constructing canons, ships and catapults as well as other weapons. He served as principle engineer in the dukes military projects. In 1502 Leonardo entered the service of Cesare Borgia, duke of Romagna. He served as Cesares chief architect and engineer. Leonardo supervised work on the fortresses of the papal territories in central Italy. In 1506 Leonardo went to Milan again at the summons of its French governor Charles dAmboise.
For the next six years he divided his time between Milan and Florence. He still continued his engineering projects and worked on a figure for a monument to a commander of the French forces in the city. Although Leonardo produced a small number of paintings he was an influent artist. The Mona Lisa, his most famous work, is a great example of two techniques sfumato and chiaroscuro of which he was one of the first great masters. Because none of Leonardos sculptural projects were brought to completion, his approach to three dimensional art can nly be judged by his drawings.
As a scientist he towered over his generation. His scientific theories were based on careful observation and precise documentation. His theories are contained in many notebooks, most of which were written in mirror script. Leonardos findings were not discovered in his own lifetime. If they had been published they would have revolutionized the science of the 6th century. Leonardo anticipated many discoveries of modern times. For instance he learned the effect of the moon on the tides.
