Leonardo da Vinci was an Italian artist, architect and scientist. He was born in 1452 at Vinci and died in 1519. Leonardo da Vinci was born the illegitimate son of a Florentine notary and a peasant girl. Despite his notorious birth, he showed promise as a child and in 1470 was sent to study art at the studio if Andrea del Verrocchio. In 1482 he settled in Milan under the patronage of Duke Ludovico Sforza, for whom he painted the 1498 'Last Supper' on a wall of the refectory of the convent of Santa Maria delle Grazie. After 1500 he entered service with Cesare Borgia, Duke of Romagna as an architect and engineer. Leonardo da Vinci recorded scientific studies in mirror writing in unpublished note books which have subsequently been discovered and designed the first helicopter (on paper) as well as recording anatomical details after carrying out dissections.
