Rocket pioneer signed 1965 BALLOON riders at the European Meeting Murren Flown Signed by German rocketeer Nebel WW1 Pilot. 29 8 65 Murren Internat Alpine Balloon Sport Postmark. Flown in Balloon riders at the European Meeting Murren Flown Signed by German rocketeer Nebel. World War I fighter pilot with Ja 5, the noted German rocket pioneer, recorded how he wanted to increase the distance at which HA could be attacked. He added two stovepipes under each wing, installed four signal rockets and attached ignition cables connected to a firing button, later an assistant hired by Oberth to fabricate the rocket. Rudolf Nebel, (1894 1978) German rocket enthusiast. Worked for Oberth; helped found VfR; built largest prewar German test rockets. Work shut down by government in 1934. Did not work on rockets during WW2. Promoted civilian rebirth of German rocketry in 1950's. Rudolf Nebel played a key role in promoting early rocketry efforts in Germany. As part of publicity for the film Frau im Mond, director Fritz Lang retained rocket pioneer Hermann Oberth as technical consultant. Lang provided Oberth with funds to build and launch a liquid propellant rocket to publicise the film. One of the assistants hired by Oberth to fabricate the rocket was Rudolph Nebel, a World War I fighter pilot with (unfortunately) little actual engineering experience. Oberth's project did not produce a rocket in time for the film opening, but Nebel had gotten the spaceflight 'bug'. He was looked down upon by his fellow space enthusiasts due to a perceived lack of technical ability. But it was Nebel that played a key role in organising the VfR; in leasing the Rakete Flugplatz rocket test ground in Berlin; in making the practical decisions that finally led to the society testing the Mirak 'Minimum Rocket'; in obtaining funding for the testing of the large scale Magdeburg rocket; and finally in arranging for the German Army to back further rocketry development. This paradoxically led to Von Braun and most of Nebel's compatriots being hired away by the German Army. Nebel continued with private experiments until shut down by a German government prohibition on further private rocket development in 1934. His colleagues, in recognition of his key role, arranged for him to receive royalties from a key rocket patent from 1937. After the second world war, the old German enthusiasm for rocketry was stirring. Nebel was one of the few German rocket pioneers who did not leave the country to work for one of the conquering powers. Despite the allied prohibition on aerospace research, Nebel, together with engineers Karl Poggensee and Albert Puellenberg, began renewed German work on rockets for peaceful purposes. They participated in the first meetings of the new International Astronautical Federation in Paris in 1950 and London in 1951. Nebel gave a lecture on rocketry and space travel in Cuxhaven on 6 April 1951. This eventually led to the establishment of 'Spaceport Cuxhaven' and a series of launches from 1958 1964 that reached into outer space. Then, once again, further private German space launches were prohibited. Born 1894 Died in 1978. Good condition. All autographs come with a Certificate of Authenticity.
