Robert
Fulton worked on developing
a practical submarine before turning his
attention to building the first
commercially viable steamboat. The result
of this latter work was the Clermont,
which was successfully tested on August
17, 1807. |

John
Philip Holland launched his
first successful submarine in 1881. The
company he founded ultimately became the
Electric Boat Company, which has
subsequently built the vast majority of
the U.S. Navy's submarines, as well as
submarines for many other nations. |
