Kramer & Loebl and Elektro Praga logos

Elektro Praga. In 2868 Gustav Kramer and Adalbert Löbl started production of refined glass and crystal lamps and chandeliers in Jablonec nad Nisou (Gablonz in the Austro-Hungarian Empire).
In 1908 they started production of accessories related to electric lighting, as sockets, plugs and switches. It proved to be a profitable market. Glass production was scaled down and ended in 1924. The company was renamed Kramer und Löbl, Fabrik elektrotechnischer Artikel (top left logo). In 1931 Kramer and Löbl introduced the Bakelite molding process in Czechoslovakia. The company became the dominant manufacturer of electrical accessories and exported products to many countries all over the world.
After annexation of Czechoslovakia in 1939 by Nazi Germany, the company was confiscated. From 1940 production was fully focused on war industry. After World War II, industry was nationalized in Czechoslovakia. Electro-technical companies were merged and renamed to Elektro-Praga. The plant in Jablonec nad Nisou had the monopoly for manufacturing electrical accessories. In 1989 state owned enterprises were privatized. In 1993 Elektro-Praga in Jablonec nad Nisou became part of the Asea Brown Boveri (ABB) concern.

Legrand. In 1865 Henri Barjaud de Lafond and Léonard Clidasson started a table porcelain workshop in Limoges. In 1904 the company was taken over by Frédéric Legrand, Charles Alary and Jean Joquel. In 1919 the product range was enlarge with manufacturing switches made of boxwood and porcelain. The addition proved to be successful; the company was renamed Legrand et Cie, Manufacture de Porcelaines et d'Appareillage électrique.
In 1949 a fire destroyed most of the porcelain production facilities. After that the directors, Jean Verspieren and Edouard Decoster decided to abandon tableware production and to focus on electrical wiring and installation equipment only. To build a strong global position many companies have been taken over, as: Pial, Brazil (1977), Pass & Seymour, USA (1984), Btichino, Italy and Latin America (1989), TCL, China (2005), HPM, Australia (2007) and many others.

According to the Maure 1932 catalog they were the first company in France producing Bakelite electrical equipment. In 1931 Germain and his brother Etienne founded the company Thermor, specialized in producing electrical household equipment. Thermor merged with Sauter in 1965 and became a part of the French Groupe Atlantic, which is still active in renewable energy applications.
The electrical accessories part of Maure was acquired by Legrand in 1951. The trademark Maure disappeared in 1988.
Schneider Electric logo

Schneider Electric. In 1836 the brothers Adolphe and Eugène Schneider acquired a foundry in Le Creusot (Burgundy region). Two years later they created the steel industry Schneider & Cie. After Wold War I the company had to reconvert to civil production. Projects related to electrification was one of the options. Comparable decisions had to made after WW II. Steel industry was still the prime option. The severe economic crisis in the mid 1970s forced the company to reconsider its strategy. The acquisition of a main interest in Merlin-Gerin (electrical distribution equipment) has influenced the decision to abandon steel industry in favour of  electrical industry. From the 1980s many acquisition followed and Schneider Electric is now a multinational corporation specialized in energy management and automation.
Soremec-Cehess logo

Societé Soremec - Cehess, in Rungis (near Paris). When and by whom the company has been founded is unknown.

The Swiss Schurter Group acquired the company in 1985.
