The Liscannor Man who invented the Sub

I was looking at part of a programme about John P. Holland (1841-1914) the inventor of the submarine last evening. Holland joined the Christian Brothers in Limerick and taught in Limerick and many other of our centres in the country. He was a man of many talents but due to ill health, he left the Christian Brothers in 1873. While in the Brothers he kept up his interest in scientific experiments. He was also interested in flying and while in Cork with the Christian Brothers he drew up designs of an aeroplane. A man of many talents, he was also musically gifted.

He was fortunate that while in Cork he had an excellent science teacher in Brother Dominic Burke, a Limerickman. Brother Burke encouraged him in his designs for a submarine and as early as 1859 he completed his first drafts for a submarine design, a design he never radically changed. He was convinced that naval warfare of the future would be run by the country that used submarines to steal close to the iron-clad battleships and attack at close range. He went to the States in 1873 but when he submitted his design for a submarine to the U.S. Navy, it was rejected as “a fantastic scheme of a civilian landsman”.

Helped financially by the Irish Fenians Holland persisted and produced "The Fenian Ram". The Government did not buy the submarine until after a final test of effort no. 6. in 1900. Holland made some alterations and after a final test in March 1900 the U.S. Government bought the Holland No. 6 for a bargain on April 12, 1900.

ah hem.



The American Turtle) was the world's first submersible with a documented record of use in combat. It was built in Old Saybrook, Connecticut in 1775 by American Patriot David Bushnell as a means of attaching explosive charges British Royal Navy vessels occupying North American harbors during the American Revolutionary War.
I like it. I like it! The diagram.
and of course, there was the Hunley, which was in service in charleston, south carolina, on the side of the confederates, during the civil war.

http://en.wikipedia.org/wiki/H._L._Hunley_(submarine) i was lucky enough to be living in charleston when the Hunley was raised, and it was *quite* exciting to be able to see the replica (which was VERY small!) that they put up in front of the local museum.
The subtender, the USS Holland was named after him too..
Cornelius Drebble, A Dutchman, invented the submarine in the late 17th century, although the USian, David Bushnell's 'Turtle' was the first practical one
Fascinating! The American Turtle and the Confederate Hunley were "submersibles" and had most but not all of their mass below the surface of the water. The Holland was apparently the first to be able to fully submerge.
