Bushnell graduated from Yale in 1775, at the outbreak of the American Revolution, and went on to build the “Turtle,” a turtle-shaped submarine which was propelled underwater by an operator who turned its propeller by hand. The “Turtle” was armed with a torpedo and several attempts were made using the Turtle against British warships. Bushnell is known as the “father of submarine warfare.”
