ギュスターヴ・エッフェル
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.
