International Astronautical Congress

From The Space Library

Summary

The Premier Congrès International d'Astronautique took place between September 30th and October 3rd 1950 beginning in the Richlieu Amphitheatre of the Sorbonne in Paris France and moving to the Aéro-Club de France on the rue de Galilée on the second day. Only the first day was open to the public. The remaining days were taken up by a conference between the attending delegates who came from France, Germany, Britain, Austria, Sweden, Spain, Argentina, and Denmark. It was later reported that 1000 people passed through the congress. The entire event had been arranged by Ananoff and Heinz Gartmann, scientific director of the GfW and a pioneer of early rocketry during the war at BMW. Gartmann was prohibited from attending the conference when denied a visa to enter France.

Four movies were screened at the event. Fritz Lang's "Frau Im Mond", V2 Launch Footage from White Sands, the science fiction film "Destination Moon", and a special presentation by Rudolf Nebel of "Experiences with Rockets at the Raketenflugplatz."

Provisions were made at the conference to meet the following year in London where the International Astronautical Federation was officially founded. It was also resolved to form a "Commission for the study of the space station project" in which the leading scientists in London the following year would give details on the possibility of implementing a space research station in a series of scientific lectures. It would also highlight the economic, cultural and political implications of the construction of a space station and, as a further important measure, prepare a list of standards prior to the London Congress, of all the symbols and designations of rocket technology.
