"M. Eiffel in his latest aerodynamical laboratory" (Aviation and Aeronautical Engineering, August 1916).

Gustave Eiffel was a French engineer who turned his attention to aero late in his career. He is credited with developing an improved type of wind tunnel.

Eiffel attended the École Polytechnique and then the École Centrale des Arts et Manufactures in Paris. He worked on various engineering projects including bridges and the Statue of Libery. He led the construction of the Eiffel Tower in 1887–1889 for the 1889 Exposition universelle.[1]

His involvement in aeronautics began with drop tests conducted at the tower, starting in 1903. He created an instrument for measuring drag on a falling object.[1]

In 1909 Eiffel constructed a wind tunnel at the Champ-de-Mars near the tower. The facility was powered by an electrical generator already housed at the tower itself. He used a new design with enlarged space and a column of air moving freely through the middle, to reduce interference with the air except that caused by the object of study.[1] Lucien Marchis called this the "Eiffel method" as opposed to the "tunnel method."[2]

Among other findings he provided clear evidence for the principle that airfoils create lift by reducing the pressure of air above them. Also, "Eiffel was the first to test models of complete airplanes in his wind tunnels and to show a correlation between test data and the actual performance of a full-size airplane.[1]

After success at the Champ-de-Mars lab he created another, with more space, at Auteuil, southwest of Paris.[1]

In 1912 he patented the "diffuser" used in these wind tunnels.[1]
