Leonardo da Vinci made sketches of a submarine at the beginning of XVI century and William Bourne, a British mathematician, drew plans for a submarine in 1578. But it was only in 1620 that Cornelius van Drebbel, a Dutch inventor, managed to build a submarine. He took the first trip with 12 oarsmen in the Thames River – staying submerged for 3 hours. Drebbel’s submarine was protected with greased leather and powered by rowers pulling on oars that protruded through flexible leather seals in the hull. Snorkel air tubes reached above the surface with floats, which allowed the boat to be submerged for several hours.
