Lawrance Aero Engine Company
Lawrance Aero Engine Company was an American aircraft engine manufacturer. Founded by engine pioneer Charles Lawrance, it designed one of the first successful air-cooled radial engines. It existed for only 5 years, being acquired by Wright Aeronautical, a much larger company better able to mass-produce Lawrance's radial engines. History The Lawrance Aero Engine Company was founded in 1917. After the end of World War I, the Lawrance engineers worked with both the Army and the Navy in developing their L-1 into a nine-cylinder radial engine, which became the 200 hp Lawrance J-1. It was the best American air-cooled engine at the time, and passed its 50-hour test in 1922.Janes Fighting Aircraft of World War I by Michael John Haddrick Taylor (Random House Group Ltd. 20 Vauxhall Bridge Road, London SW1V 2SA, 2001, ), page 290 The United States Navy was very enthusiastic about air-cooled radials, but was concerned that Lawrance couldn't produce enough engines for its needs.

Charles Lanier Lawrance (September 30, 1882 – June 24, 1950) was an American aeronautical engineer and an early proponent of air-cooled aircraft engines. Early life Lawrance was born on September 30, 1882 in Lenox, Massachusetts, the son of Francis Cooper Lawrance Jr. (1858–1904) and his first wife, Sarah Eggleston Lanier (1862–1893). After his mother's death in 1893, his father remarried to Susan Ridgeway Willing, a sister of Ava Lowle Willing (who married John Jacob Astor IV). They had a daughter, a half-sister to Lawrance, Frances Alice Willing Lawrance, who married Prince Andrzej Poniatowski of the House of Poniatowski in 1919. From his parents marriage, Lawrance had a younger sister, Kitty Lanier Lawrance, who was raised by their paternal grandfather, as their parents died when she was still young. In 1915, Kitty married W. Averell Harriman, the Governor of New York (they divorced in 1928). Lawrance's maternal grandfather was banker Charles D. Lanier, a close friend ...

Wright Aeronautical
Wright Aeronautical (1919–1929) was an American aircraft manufacturer headquartered in Paterson, New Jersey. It was the successor corporation to Wright-Martin. It built aircraft and was a supplier of aircraft engines to other builders in the golden age of aviation. Wright engines were used by Amelia Earhart and Charles Lindbergh. In 1929, the company merged with Curtiss Aeroplane and Motor Corporation to form Curtiss-Wright. History In 1916, the Wright brothers' original aviation firm, the Wright Company, merged with Glenn L. Martin's firm, the Glenn L. Martin Company of California, to form the Wright-Martin Aircraft Corporation. In September 1917, Martin resigned from Wright-Martin and re-formed an independent Glenn L. Martin Company of Ohio (later of Maryland). After World War I in 1919, Wright-Martin was renamed Wright Aeronautical. It moved to Paterson, New Jersey in 1919. In February 1919, an airplane with a Wright engine broke the world's speed record at 163 2� ...
