David bushnell submarine biography of abraham maslow

David Bushnell is credited as the inventor of the submarine, which was first used to launch explosives against British ships during the American Revolution Under a different identity, the New England native settled in Georgia after the war and spent the rest of his life there. Accounts describe him as reticent, quiet, distant, and exceedingly private.

When his father died, Bushnell sold his inheritance and moved to town, where he could prepare for higher education. While a student, Bushnell experimented with exploding timed gunpowder charges under water. During his final year at Yale, he spent his last penny constructing a manned submarine capable of employing weapons.

Built entirely of oak beams, the elliptical craft resembled two conjoined turtle shells.

While Lee was not able to attach the explosive to the ship, he was able to detonate the charge. After two more unsuccessful attempts, Bushnell determined that better-trained operators were required and turned his attention to using mines to strike the enemy. The captain of the HMS Cerebus avoided destruction by simply cutting the rope carrying the mines, but they did destroy a nearby schooner.

Bushnell reworked his design and tried again later in the year. This time, he devised a mine suspended by wooden kegs that would detonate on contact.
