3Gustave Eiffel also had a hand in another monument you might have heard of

In 1879 the internal designer for the Statue of Liberty (also built in France), Eugene Viollet-le-Duc, died suddenly, leaving the construction crews in desperate need of someone who knew a thing or two about building large metal towers.

Eiffel and Koechlin rejected Viollet-le-Duc’s original idea to make the bronze exterior of Lady Liberty bear all her weight and instead installed an iron skeleton inside of her for support.
