He produced the two most famous paintings in history, The Last Supper and the Mona Lisa. But Da Vinci was just as much a man of science and technology. With an obsessive passion, he pursued innovative studies of anatomy, fossils, the heart, flying machines, botany, and weaponry. His ability to stand at the crossroads of the humanities and the sciences, made iconic by his drawing of Vitruvian Man, made him history's most creative genius. A NY Times bestseller and the new biography from the author of "Steve Jobs".
