Cornelius Henry DeLamater
Birth: Aug. 20, 1821
Dutchess County
New York, USA
Death: Feb. 7, 1889
New York
New York County (Manhattan)
New York, USA

Inventor, Industrialist. He constructed the world's first successful submarine torpedo boat. Co-designed the iron clad U.S.S. Monitor along with his Swedish friend Jon Ericsson. This vessel stopped the Merrimac at Hampton Roads, Virginia, on March 9, 1862, in history's first battle between ironclads. During the battle, DeLamater, who owned the Phoenix Company which constructed parts of the vessel, used his own civilian employees to operate the Monitor's boilers and turret machinery. These men later returned to their jobs at the company located in New York. After the war, he went on to invent and manufacture firefighting pumps, engines, industrial presses, mechanical refrigeration equipment, hydraulic stage machinery, and what every child remembers, the great cannon which shot the human cannonball during circus performances. It was actually a gigantic spring. (bio by: Paul S.) 
Son of William & Eliza Delamater, interred in Woodlawn, New York.
