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.
Born in Pleasantville, New Jersey on September 4, 1866. Lake joined his father's foundry business after attending public schools in New Jersey and Pennsylvania. Lake had a strong interest in undersea travel.
He built his first submarine, Argonaut Junior, in 1894 in response to an 1893 request from the Navy for a submarine torpedo boat. In 1898 he followed up with the 36-foot Argonaut 1, which he sailed from Norfolk, Virginia for a thousand miles to Sandy Hook, New Jersey, arriving in November, 1898.  As a result of lessons learned on that journey, he rebuilt it into the 60-foot Argonaut 2.
Neither Argonaut nor Lake's following submarine, Protector, built in 1901, were accepted by the Navy. Protector was the first submarine to have diving planes mounted forward of the conning tower and a flat keel. Four diving planes allowed Protector to maintain depth without changing ballast levels. Protector also had a lock-out chamber for divers to leave the submarine. Lake, lacking Holland's financial backing, was unable to continue building submarines in the United States. He sold Protector to Imperial Russia in 1904 and spent the next seven years in Europe designing submarines for the Austro-Hungarian Navy, the Kaiserliche Marine, and Imperial Russian Navy (Osetr class submarines and Kaiman class submarines).
He lived in Milford, Connecticut from 1907 until his death in 1945. A grammar school named in his honor closed in June 2010. In 1912, he founded the Lake Torpedo Boat Company in Bridgeport, Connecticut, which built 24 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 (78m) in November 1912.
In 1922 the United States and other countries signed treaties limiting the size of their navies. This led to financial difficulties which forced the Lake Torpedo Boat company to close in the mid-1920s. Following the company's closure, Lake continued designing maritime salvage systems including obtaining permission to partially salvage the Lusitania off the south Irish coast and then later a failed attempt to salvage gold from HMS Hussar, a British frigate that sank in 1780 in New York's East River with his submarine, the Explorer. He advised the United States Navy on submarine technology and maritime salvage during World War II.
He died on June 23, 1945.
By his death, Lake had witnessed the submarine's arrival as a front-line weapon in the US Navy.
In 1989 Simon Lake was inducted into the Toms River Schools Hall of Fame.
