In 1920, the aeronautical engineer Emile Dewoitine created a design office called "La Société des Avions Dewoitine".
The following year he designed a monoplane, the D.1, which was revolutionary at the time, with a combination of steel and aluminum construction, a monolongeron wing structure, and a hard-wearing skin. A visionary, he decided to manufacture the D.1 in his own workshop, which he set up in Les Minimes, the CAED (Constructions Aéronautiques Emile Dewoitine). Marcel Doret, who was hired as a test pilot by Dewoitine in 1923, broke three world records in December 1924.
Strengthened by his success, Emile Dewoitine surrounded himself with a competent and loyal team, led by his charismatic chief pilot Marcel Doret. His name quickly became synonymous with quality, and the number of prototypes grew, both military and civilian, transport, record or racing aircraft.
Emile Dewoitine was the father of the most beautiful and efficient machines of his time, such as the D.33 "Trait d'Union", the first plane in France to fly 10,000 km in a closed circuit without refueling, or the majestic D.338 airliner that flew the Air France colors from Paris to Hanoi, Dakar or Hong Kong...
Emile Dewoitine also marked aeronautical history by creating a great line of terribly powerful and racy fighter planes. By dint of constant innovation and improvement, this lineage led in 1936 to the creation of the Dewoitine D.520, then reputed to be the best fighter that France was able to field during the Battle of France.
