[ 1620 ] Dutch physician Cornelis Jacobszoon Drebbel builds the first submarine made of wood reinforced with iron and covered with leather. Like Bourne’s earlier design, it is oared from the inside by a 12-man crew. The sub is operated successfully in the Thames River at depths of up to 4.6 m (15 ft) for three hours. Between 1620 and 1624 Drebbel builds two larger submarines. The third model has 6 oars and can carry 16 passengers. King James I even takes part in a test dive and thus becomes the first monarch to travel underwater.
