Leonardo da Vinci (April 15, 1452 May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. He has been described as the archetype of the "Renaissance man" and as a universal genius, a man both infinitely curious and infinitely inventive.
