The Eiffel Tower was designed by Gustave Eiffel, who was born in 1832 in Dijon, in eastern France. At the age of 20, he was admitted to the French National Institute of Technology to train engineers with excellent results. There he rented a single dormitory, often squeezing in the middle of the table and the stove and burying his head in the middle of the night. Soon, he received a diploma from an engineer with good grades. After graduating, Eiffel was introduced as a engineer to the Research Office of the Western Railway Administration. Since then, Eiffel has embarked on the path of a building structural engineer to contribute his outstanding talents to human progress and civilization.
