LEONARDO

Leonardo da Vinci is a well known 15th and 16th century artist.  You may not know that he was also an architect and engineer and may also have been the best inventor of all time.  He drew his inventions and they were found among his art works.  Most were way ahead of their time and, since he didn't share them with others, were not implemented until much later.  Here are a few items with which he is credited with inventing:  ball bearings, parachute, ornithopter, machine gun, diving suit, armored tank, self-propelled cart, sanitary city, helicopter and robotic knight.  He was way, way ahead of his time.  Be ahead of your time.
