In 1926, AEG AG acquired the properties in the Hoffmannstraße in Berlin-Treptow. At this location the company Apparate-Werke-Berlin-Treptow (AT) quickly developed into a considerable manufacturer of switching devices, electrical measuring instruments and meters as well as relays, radios and mercury vapor power converters.
