About Gema: Birthplace of German Radar and Sonar

In Germany, the development of the first technologies of sonar and radar were interrelated. Following Christian Hülsmeyer's forgotten invention of the Telemobiloskop in 1904, two Berlin engineers, Paul Günther Erbslöh and Hans-Karl von Willisen, developed and built devices to locate targets accurately by reflections with underwater sound and radio waves. In 1934, they found their own company for this work, called Gesellschaft für Elektroakustische und Mechanische Apparate (GEMA), which became the birthplace of their famous Freya air-warning and Seetakt ocean-surveillance radars.
