The design of the Eiffel Tower was the product of Maurice Koechlin and Émile Nouguier , two senior engineers working for the Compagnie des Établissements Eiffel , after discussion about a suitable centrepiece for the proposed 1889 Exposition Universelle , a world 's fair to celebrate the centennial of the French Revolution . Eiffel openly acknowledged that inspiration for a tower came from the Latting Observatory built in New York City in 1853 . In May 1884 , working at home , Koechlin made a sketch of their idea , described by him as `` a great pylon , consisting of four lattice girders standing apart at the base and coming together at the top , joined together by metal trusses at regular intervals '' . Eiffel initially showed little enthusiasm , but he did approve further study , and the two engineers then asked Stephen Sauvestre , the head of company 's architectural department , to contribute to the design . Sauvestre added decorative arches to the base of the tower , a glass pavilion to the first level , and other embellishments .

French demographer , anthropologist and historian Alfred Sauvy , in an article published in the French magazine L'Observateur , August 14 , 1952 , coined the term Third World ( French : Tiers Monde ) , referring to countries that were unaligned with either the Communist Soviet bloc or the Capitalist NATO bloc during the Cold War . His usage was a reference to the Third Estate , the commoners of France who , before and during the French Revolution , opposed the clergy and nobles , who composed the First Estate and Second Estate , respectively . Sauvy wrote , `` This third world ignored , exploited , despised like the third estate also wants to be something . '' He conveyed the concept of political non-alignment with either the capitalist or communist bloc .
