"Da Vinci. The mad man designed a tank in the 1500s.
However, he designed the gearbox backwards to make any real version’s wheels lock up and fail. He also designed a 12-barrel gun carriage, which is basically the machine gun on steroids, the early parachute, the double hull, the use of concentrated solar power, and a calculator. The man was several centuries ahead of his time."
