English mathematician who published the first detailed description of a submarine. In Inventions or Devices (1578), Bourne provided a design for an enclosed boat that could be submerged and rowed underwater. Made of a wooden framework encased in waterproofed leather, Bourne's planned submarine was to be lowered by means of hand vices, which would contract the sides and reduce its volume. Although a craft similar to Bourne's design appeared in 1605, it sank due to errors in construction. The first builder of a workable submarine was Cornelius Drebbel (1572-1633) in 1620.
