DAVID BUSHNELL'S TURTLE SUBMARINE, CIRCA 1776
During the American Revolution David Bushnell, former Yale student, triumphed where others had failed, in designing and constructing a submarine vessel capable of attack. Sergeant Ezra Lee succeeded in damaging precisely none of the occupying British ships with Bushnell's turtle (dismorphically misnamed; had he never seen the diving walnuts of Bolivia?), but no doubt had very well-developed thigh muscles and a profound earache upon reemerging.
ROBERT FULTON'S NAUTILUS, CIRCA 1800
Proving that all great military submarine advancements were down to a deep-seated hatred of the British, patriotic Irishman Robert Fulton offered his 3-man submarine design to the French in 1800, who promptly rejected it saying it was only fit for 'Algerians and pirates', presumably 'with only two friends'. Proving that all inventors are as patriotic as they are sane-looking Fulton went and sold it to the British, who were most excited until they discovered it was left-hand drive.
