Eiffel Tower was not dismantled as it served as antenna
The Paris authorities had planned to dismantle the Eiffel Tower for scrap metal in 1909, 20 years after it was inaugurated. The tower was spared as the antenna atop of it could be used for sending and receiving wireless messages, particularly for the French military. Eiffel Tower was named after its engineer Gustave Eiffel, who died on December 27, 1923.
