The development of radio engineering

A review is provided of the development of radio engineering in Germany during the time period from 1897 to 1969, when sections of the German Experimental Institute for Aviation were incorporated into the 'German Research and Experimental Institute for Aeronautics and Astronautics. Techniques for radiotelephony communication between airships, aircraft, and ground stations were established during the period from 1897 to 1918. Developments occurring during the time from 1919 to 1937 are related to fundamental investigations regarding the behavior of electromagnetic waves, methods for the remote control of vehicles, position finding techniques, and approaches for making the landing of airships under conditions of poor visibility possible. Navigation methods and long-range radio communication were developed during the time from 1927 to 1945.
