As early as 1889, the Eiffel Tower served as a laboratory for scientific measuring and experimenting. A certain number of scientific devices were present on the site for these purposes : barometers, anemometer, lightning conductors…Three avant-garde domains found their laboratory quite naturally suited for the Tower. Meteorologists were able to employ numerous instruments testing the variation in pressures and humidity, whereas radiotelegraphy and aerodynamics researchers observed falling objects at great heights.

With the recognition of the Tower's scientific utility, it had won the right to be preserved as a monument. The Tower was to have originally been torn down after 20 years of existence. He also kept himself a studio on the third level to make astronomical and physiological observations, and in 1909 he had a small wind tunnel built at the foot of the Tower
