Delaunay's Eiffel Tower series is evoked in architectural paintings of other iconic buildings by his contemporary, the New York artist John Marin, in his "Woolworth Building, No. 31" of 1912, and later by the Ontario artist Greg Curnoe's "CN Tower" series of the 1970s and 1980s. The 1913 artist's book "La prose du Transsibérien et de la Petite Jehanne de France", a collaborative work between Sonia Delaunay and the poet Blaise Cendrars, forms an epic narrative of a Trans-Siberian Railway journey that concludes in Paris at a Simultanist Eiffel Tower.

Gustave Eiffel Using this Eiffel definitely established that the air resistance of a body was very closely related to the square of the airspeed. He then built a laboratory on the Champ de Mars at the foot of the tower in 1905, building his first wind tunnel there in 1909. The wind tunnel was used to investigate the characteristics of the airfoil sections used by the early pioneers of aviation such as the Wright Brothers, Gabriel Voisin and Louis Blériot. Eiffel established that the lift produced by an airfoil was the result of a reduction of air pressure above the wing rather
