Allgemeine Elektrizitäts-Gesellschaft Aktiengesellschaft (AEG) was a German producer of electrical equipment founded in 1883 by Emil Rathenau. The company was headquartered in Frankfurt am Main, Germany.
In 1907 architect Peter Behrens became an artistic adviser. Responsible for the design of all products, advertising and architecture, he has since become considered as the world's first corporate designer. Behren's philosophy was to create a building which is solid, strong and simple in its structure. It is perfect for doing its job of producing large, heavy machinery. The dimensions of the building were chosen to allow turbines to be transported above other machinery.
In the 1920s AEG became a global supplier of electrical know-how and equipment. In 1923, for example, it provided most of the essential materials and a team of engineers to oversee the electrification of British-ruled Palestine. British firms, at the time, could not compete with the prices of AEG.
The activity of the company soon extended to all areas of electrical power engineering, including electric lighting, electric power, electric railways, electro-chemical plants, as well as the construction of steam turbines, automobiles, cables and cable materials. In the first decades, the company had many factories in and around Berlin.
