The story of the Mosquito begins with the founding of Geoffrey de Havilland’s aircraft company which bore his namesake, de Havilland. Around 1908, de Havilland designed his first aeronautical engine, which he then used to power his first aircraft — a small biplane. In 1920, when the aircraft company he worked for — Airco — shut down, he was able to create his own company, de Havilland Aircraft Company Limited, more commonly known as de Havilland.
