But one of his employees—engineer Maurice Koechlin—did. In fact, Eiffel rejected Koechlin’s original sketches, calling them too minimalist and requesting a little more oomph. After
approving Koechlin’s final design in 1884, Eiffel started shopping his company’s masterpiece around.
In late 1916, engineers at the Tower’s listening post intercepted another message. This one had been sent from
Germany to Spain, a country that had not entered the war. The message referred to an agent known as “Operative H-21.” The French realized that this was the code name for the Dutch exotic dancer born Ma

The French battled the Ger

By September 1914, just weeks into World War I, it looked like the German army would overrun France. German battalions wer

The Eiffel tower could easily be used to transmit radio signals secretly or even to transmit brain-like waves which will m
