At the beginning of the last century, two rival research groups were working in the field of wireless telegraphy. The Slaby-Arco group was represented by the radio-telegraphy department of AEG, founded in 1899. The other as the Braun-Siemens group, represented by a company called Gesellschaft für drahtlose Telegraphie, System Prof. Braun und Siemens & Halske GmbH.   Under the advice of Emporer Wilhelm II, the two groups merged to form the Gesellschaft für drahtlose Telegraphie mbH company on May 27, 1903. And the rest is history.

The very first Telefunken customers were the German Army and the Imperial Navy. Telefunken was proud to deliver the first two transmitters for the new coastal radio station, Norddeich Radio, in November 1905. In October 1906, the expansion of a much larger Nauen station was completed with a range of 300 km and HF output of 10 kW. Welcome to the power of Telefunken.

Dr. Georg Graf Von Arco was the first Technical Director and Managing Director of the Gesellschaft für drahtlose Telegraphie mbH in 1903. He was also the holder of more than one hundred patents. Among other inventions, he initiated the high-frequency mechanical transmitter and the wavemeter. Necessity is the mother of invention. Or in this case, German inventions.
