On June 6, brothers Louis and Laurent Seguin found the "Société des Moteurs Gnome" in the Paris suburb of Gennevilliers.
In just a few short years, their Gnome rotary engines would become the standard for aeroplanes around the world. These engines were a revolution at the time, in terms of weight savings, engine cooling and operational reliability, because of the "flywheel" effect of the cylinder block rotating at high speed.
Marc Birkigt creates the Hispano-Suiza works in France to produce automobiles (after the original company was founded in Spain in 1904).
Louis Verdet founds the Société des Moteurs Le Rhône, which quickly becomes Gnome's main competitor.
On September 23, Roland Garros makes the first flight across with Mediterranean on a Morane-Saulnier H monoplane powered by a Gnome Sigma rotary engine.
Hispano-Suiza starts to manufacture aircraft engines, which will become market leaders starting in 1916.
Gnome takes over Le Rhône, becoming the Société des Moteurs Gnome et Rhône. By the end of the 1920s, this company will be one of the world's leading makers of aircraft engines.
Creation of the company Labinal.
Marcel Môme creates the Société d'Applications Générale d'Electricité et de Mécanique (SAGEM), whose primary business is the production of power supplies for telephone switching centers.
SFMA is renamed Messier.
Joseph Szydlowski founds the company Turbomeca, specialized in the manufacture of compressors for aircraft engines.
Sagem takes control of the Société d'Application Téléphonique, which would later become the Société Anonyme de Télécommunications (SAT).
France creates SEPR (Société d'Etudes pour la Propulsion par Réaction), specialized in research on rocket propulsion for aircraft.
Gnome & Rhône is nationalized, taking the name of SNECMA (Société Nationale d'Etude et de Construction de Moteurs d'Aviation) and grouping most French aero-engine manufacturers, whose history dated back to the beginning of the century (Renault, Lorraine, Régnier, etc.).
In June, the first inertial reference system designed by Sagem takes flight on a Nord 2501 missile at the Brétigny-sur-Orge flight test center. The system weighs 500 kg!
Hispano-Suiza joins the Snecma group.
SEPR is merged with Snecma's space and missiles division, creating the company SEP (Société Européenne de Propulsion).
Snecma and General Electric create CFM International, an equally-owned company in charge of the design, development, sale and support of CFM56 engines. Today, this is the world's best-selling engine for mainline commercial jets with over 100 seats.
Following a series of mergers and consolidations started in 1971 between Snecma, Hispano-Suiza, Messier and Bugatti, creation of the company Messier-Hispano-Bugatti to group all landing gear business. Hispano-Suiza continues to develop its aircraft equipment business, and builds its first thrust reversers.
Sagem acquires Morpho, a specialist in fingerprint-based biometric recognition systems.
Creation of landing gear specialist Messier-Dowty.
