Simon Lake

Simon Lake (September 4, 1866 – June 23, 1945) was a Quaker American mechanical engineer and naval architect who obtained over two hundred patents for advances in naval design and competed with John Philip Holland to build the first submarines for the United States Navy.

Protector was the first submarine to have diving planes mounted forward of the conning tower and a flat keel.

Lake, lacking Holland's financial backing, was unable to continue building submarines in the United States.

In 1912, he founded the Lake Torpedo Boat Company in Bridgeport, Connecticut, which built 26 submarines for the United States Navy during and after World War I.

Lake's first submarine for the U.S. Navy, USS G-1 (SS-19½), set a depth record of 256 feet (78 metres) in November 1912.

[4] Lake redesigned the former USS O-12 (SS-73) as the Arctic exploration submarine Nautilus, used by Sir Hubert Wilkins in a 1931 expedition.

He also advised the United States Navy on submarine technology and maritime salvage during World War II.
