Snecma
In 1905 Louis Seguin created the company Gnome. Production of the first rotary engine for airplanes, the Gnome Omega, started in 1909. This company merged with the Le Rhône, a company created in 1912 by Louis Verdet, to form the Gnome et Rhône engine company. Gnome & Rhône was nationalized in 1945, creating Snecma. In 2000, this company gave its name to the “Snecma Group”, and carried out a number of acquisitions to form a larger group with an array of complementary businesses.
