Contribution to the Eiffel Tower

In 1884 Nouguier and the structural engineer Maurice Koechlin, who also worked for Eiffel, came up with the idea of a large tower to act as the centrepiece of the Universal Exposition which was to be held in 1889. The two engineers consulted Stephen Sauvestre, head of the architectural division of the Eiffel company, who added embellishments including the decorative arches of the base and the glazed pavilion on the first level. The proposal was put before Eiffel, who approved the project, and presented it to the French Minister for Trade and Industry.

In 1884 Gustave Eiffel, Émile Nouguier and Maurice Koechlin registered a patent for the construction of pylons with heights of over 300 m. Later Gustave Eiffel bought the rights from the other two for one percent of the total earnings of the tower if it will be built. They received around 50,000 francs.

In 1893 Émile Nouguier resigns from the Gustave Eiffel Entreprise and becomes co-president of the Nouguier, Kessler et Cie Company in Argenteuil, Île-de-France. He continued to work for many important projects:
