De Haviland was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware in north London. Operations were later moved to Hatfield in Hertfordshire. Known for its innovation, de Havilland was responsible for a number of important aircraft, including the Moth biplane which revolutionised aviation in the 1920s; the 1930s Fox Moth, a commercial light passenger aircraft; the wooden World War II Mosquito multirole aircraft; and the pioneering passenger jet airliner Comet. In 1960 it became part of Hawker Siddeley Group and later merged into the BAE Systems.
