Henri Cobioni quit motorcycle racing in September 1909 and built this little monoplane at his home in Moutier/Münster, Switzerland. He had to collect money for the engine, which was installed in about March 1910. Flight testing took place at the “Allmend” of Thun, where Cobioni could make a few hops, but finally crashed the machine in June 1910. After that he entered the Caproni school and qualified for the Swiss FAI-brevet No.15 in August 1911. The construction of this first monoplane is credited to Eng. Emilio Lazzaroni from Milano, who together with Cobioni patented the machine and founded the company “La Société Jurassiene d’Aviation”, which was quickly dissolved after the Cobioni’s crash.
