1 Gnome
2 Le Rhne
The Gnome rotary engine took the aviation world by storm in 1909 with its light weight (60 kg) and power (34 hp).  Le Rhne produced its first rotary engine in 1910.  These two companies merged in 1915 and improved the rotary engine through World War I.

After the War Gnome-Rhne re-focused its efforts on radial engines, at first by license building Bristol products.  Gnome-Rhne formed the basis of SNECMA after World War II.
