who invented the submarine in the industrial revolution
David Bushnell Bushnell is credited with creating the first submarine ever used in combat, while studying at Yale in 1775. He called it the Turtle because of its look in the water. His idea of using water as ballast for submerging and raising his submarine is still in use, as is the screw propeller, which was used in the Turtle.
Second Industrial Revolution The Second Industrial Revolution, also known as the Technological Revolution,[1] was a phase of rapid industrialization in the final third of the 19th century and the beginning of the 20th. The First Industrial Revolution, which ended in the early to mid 1800s, was punctuated by a slowdown in macroinventions[clarification needed] before the Second Industrial Revolution in 1870. Though a number of its characteristic events can be traced to earlier innovations in manufacturing, such as the establishment of a machine tool industry, the development of methods for manufacturing interchangeable parts and the invention of the Bessemer Process to produce steel, the Second Industrial Revolution is generally dated between 1870 and 1914 (the start of World War I).[2]
