When Von Kármán approached Levi-Civita in 1922 suggesting a scientific meeting on fluid dynamics he knew that such a meeting could not be an official congress if German and Italian scientists were both involved so he proposed an informal one. Levi-Civita was enthusiastic but when the meeting took place in Innsbruck in September of that year the only scientists from the Allied Powers to participate were Levi-Civita and members of his research group.
