He enters the Central School of Paris to study Chemistry and when he graduated, he became interested in Metallurgy, having then the opportunity to work in this sector thanks to his mother's relationships and contacts.
He ends up being employed by Charles Nepveu, a steam engine builder engineer who also manufactured material for the iron lines. A year later, in 1857, Gustave Eiffel became head of the studies and projects office at Pauwels e Cia. His first major project was the construction of the Bordeaux Bridge (more than 500 meters), at the age of just 25.
From then on, he will be in charge of the design of several other bridges in the Southwest region.
Gustave Eiffel ends up settling in late 1866 west of Paris. In 1867 he started his own company and started to build several buildings that would increase his reputation in France and around the world. It perfects its technical innovations, especially when assembling so-called consoles, or cantilevers.
During the 1870s and 1880s, the Eiffel company is at its peak and is in demand worldwide. The construction works are increasingly complex and carried out with pride (we can mention, in particular, the Statue of Liberty, in New York, whose structure that supports the weight of Bartholdi's sculpture, was all elaborated by Gustave Eiffel). Associated with the work of Gustave Eiffel, we find, obviously, the realization of what has become the symbol of France: the Eiffel Tower.
