The company became known simply as Donnet after designer Denhaut left it in 1919 (replaced by Maurice Percheron), but did not continue to build aircraft for long afterwards.
Jérôme Donnet purchased Automobiles Zedel of Pontarlier, Doubs, France in 1919,[1] and changed the name of the enterprise to Donnet-Zedel.
By the time of the 25th Paris Motor Show, in October 1931, substantial investment at Nanterre enabled the manufacturer to boast of having the most up-to-date automobile factory in France (...la plus récent des usines d'automobiles françaises...).
[3] At the 1931 motor show, Jérôme Donnet was keen to put behind him the economic troubles that accompanied the Great Depression, and he was promoting a front-wheel drive 11CV design which had been submitted to him by the (already high-profile) automotive engineer Jean-Albert Grégoire.
[5] The little car had never been sold in great volume by its previous manufacturer, and rebadged as a Donnet failed to improve its appeal.
