[1] Although he was concerned about the wind resistance of structures, Gustave Eiffel did not do a great deal of work on this issue.

He carried out very few wind tunnel tests on this specific subject and only studied one of his constructions, the Garabit viaduct.

[3] As early as 1915, Gustave Eiffel put his facilities and knowledge at the service of the Peugeot Company to improve the performance of a racing car.

[4] This activity remained marginal until 1950, but then developed very rapidly at the request of the car industry.

[5] From 1945, the Eiffel Laboratory's facilities were used to determine the wind dimensions of engineering structures.
