Travellers flying into Paris would not connect the famous 100-year-old landmark, the Eiffel Tower, an immense and complex structure of open ironwork, 300 m high, with the aerodynamics of their streamlined modern aeroplane. The unexpected association between the two is Gustave Eiffel — ‘le magicién de fer’ — builder of the Tower in 1889, who pioneered much of the experimental research needed by the designers of the first aeroplanes, in the period from 1903, when he was in his ‘70s, until the time of his death aged 90 in 1923.
Post-Second World War generations of aerodynamicists are also probably unaware that Eiffel was the source of many of the basic results they use, since no modern textbooks refer to his researches of 70 years ago; yet nearly half of his obituary notice in the Times of 29 December 1923, headed ‘M. Eiffel — A Great Engineer’ referred to his aeronautical research using his Tower and his wind-tunnels. In order to appreciate how Eiffel came to embark on his new activities at such a late age we must look briefly at his first career, which established him as one of the most distinguished structural engineers of the 19th century, and the political scandal which brought it to an end.
