John Philip Holland

Died 12 Aug 1914 at age 74 (born 29 Feb 1840).Irish inventor known as the “father of the modern submarine,”who designed and built the first underwater vessel accepted by the U.S. Navy. In 1873, he emigrated to the U.S. where, with financial support from the Irish Fenian Society (who hoped to use submarines against England), he built the Fenian Ram, a small sub that proved a limited success in a test run. In 1895, his J.P. Holland Torpedo Boat Company received a contract from the U.S. Navy to build a submarine, and in 1898 a successful Holland, the first truly practical submarine, was launched. The U.S. government ordered six more; similar orders came from England, Japan, and Russia. Holland's final years were marked by litigation with his financial backers.[EB gives birth date as 29 Feb. Some sources give 24 Feb.]
