Written History of IUTAM

In the beginning was Theodore von Kármán, professor in Aachen (Germany), who had the strong feeling that scientists in the field of fluid mechanics should meet each other. The time was 1922, a period in which the ravages of World War I were still present and scientific congresses were still rare. Nevertheless, Von Kármán succeeded and some thirty people, all Europeans, met in Innsbruck to talk and listen.
