The British mathematician and writer William Bourne proposed one of the earliest designs for a submarine in 1578.

His concept featured a boat with a wooden frame covered in waterproof leather. The design intended for the vessel to be submerged by using hand vises to contract the sides, thereby reducing its volume. While Bourne provided the first serious discussion of such a craft, he did not construct it; the first successful submarine was later built by the Dutch inventor Cornelis Drebbel in the early 17th century.1
