Leonardo da Vinci 1452 - 1519 · Florence and Milan, Italy
Leonardo da Vinci was an Italian artist, scientist, and inventor. He was born in 1452 in the small town of Vinci, near Florence, in what is now Italy. His name means 'Leonardo from Vinci'. He was the son of a young woman named Caterina, who was probably a peasant or servant, and a wealthy notary named Ser Piero. His parents never married. Leonardo grew up in his father's family but was treated as a separate, somewhat outside figure. He showed great talent young. As a teenager he was apprenticed to the artist Andrea del Verrocchio in Florence. He learned painting, sculpture, and many practical crafts. Around the age of 30, he moved to Milan to work for the Duke, Ludovico Sforza. He stayed in Milan for nearly 20 years. He painted, designed weapons, planned buildings, and filled notebooks with ideas. When French armies invaded Milan, Leonardo moved on. He worked in Florence, Rome, and other Italian cities. He served various rulers, including Cesare Borgia and the Medici. In 1516, the king of France, Francis I, invited him to come and live in France. Leonardo accepted. He spent his last three years in a small castle near the king's palace at Amboise. He died there in 1519, aged 67. He never married and had no children. He was probably gay, though the evidence is indirect. He was vegetarian, unusual for his time. He left thousands of notebook pages full of drawings and ideas, most of which were not read for centuries.
