The Eiffel Tower, an immense stucture of exposed latticework supports made of iron, was erected for the
Paris Exposition of 1889. The Prince of Wales (later King Edward VII of England) officiated at the ceremonial opening. Of the
700 proposals submitted in a design competition, one was unanimously chosen, a radical creation from the French structural engineer
Alexandre Gustave Eiffel (b. Dec. 15, 1832, d. Dec. 28, 1923), who was assisted in the design by engineers
Maurice Koechlin and Emile Nouguier, and architect Stephen Sauvestre.
However, the controversial tower elicited some strong reactions, and a petition of
300 names — including those of Maupassant, Emile Zola, Charles Garnier (architect of the Opéra Garnier), and Dumas
the Younger — was presented to the city government, protesting its
construction. The petition read, “We, the writers, painters, sculptors,
architects and lovers of the beauty of Paris, do protest with all our
vigour and all our indignation, in the name of French taste and
endangered French art and history, against the useless and monstrous
Eiffel Tower.”
Nature lovers thought that it would interfere with the flight of birds over Paris. But the
Eiffel Tower was admired by Rousseau, Utrillo, Chagall, and Delaunay.
It was almost torn down in 1909 at the expiration of its 20-year lease,
but was saved because of its antenna — used for telegraphy at that
time. Beginning in 1910 it became part of the International Time
Service. French radio (since 1918), and French television (since 1957)
have also made use of its stature. In the 1960s, it was the subject of a
wonderful study by semiologist Roland Barthes.


Built to celebrate the science and engineering achievements of its
age, soaring 300m / 984 ft. (320.75m / 1,052 ft. including antenna) and
weighing 7000 tons, the structure consists of two visibly distinct
parts: a base composed of a platform resting on four separate supports
(called pylons or bents) and, above this, a slender tower created as the
bents taper upward, rising above a second platform to merge in a
unified column.
This unprecedented work, the tallest structure in the world until the
Empire State Building was built about 40 years later, had several
antecedents. Among them were the iron-supported railway viaducts
designed by Eiffel, an arch bridge over the Douro River in Portugal with
a span of 160 m (525 ft), and a design for a circular, iron-frame tower
proposed by the American engineers Clarke and Reeves for the Centennial
Exposition of 1876. Eiffel knew and publicly acknowledged this
influence; he was no stranger to the United States, having designed the
wrought-iron pylon inside Frederic Bartholdi’s Statue of Liberty in
1885. Later in the same year, he had also begun work on the cupola of
the Nice observatory.
Eiffel was the leading European authority on the aerodynamics of high frames (he wrote “
The Resistance of the Air”
in 1913). In the construction of the Eiffel Tower, the curve of the
base pylons was precisely calculated so that the bending and shearing
forces of the wind were progressively transformed into forces of
compression, which the bents could withstand more effectively. Such was
Eiffel’s engineering wizardry that even in the strongest winds his tower
never sways more than 4-1/2 inches. The superskyscrapers erected since
1960, such as the World Trade Center, were constructed in much the same
way.
However difficult its birth may have been, the Tour Eiffel is now
completely accepted by French citizens, and is internationally
recognized as one of the symbols of Paris itself.
Facilities and Views
In
the basements of the eastern and western pillars, one can visit the
gargantuan 1899 machinery which powers the elevators, an astonishing
spectacle reminiscent of a Jules Verne novel. From the Tower’s three
platforms — especially the topmost — the view of Paris is superb. It
is generally agreed that one hour before sunset, the panorama is at its
best; don’t forget to bring your camera, and experiment with the f-stop
settings to capture a dazzling sunset on the Seine. If you can’t be
there in person, then check out a Live Aerial View of Paris with TF1′s
webcam online: from the top of the Eiffel Tower, you can see Paris in
real time, 24 hours a day, whatever the weather conditions in the French
capital. To get the most out of this view of Paris, we suggest you surf
their web site between 7:00 AM and 9:00 PM GMT (1:00 AM and 3:00 PM
Eastern Time in the U.S.), when the City of Light is at its best.

lifetime, the Eiffel Tower has witnessed a few strange scenes, including
being scaled by a mountaineer in 1954, and two Englishmen parachuting
off it in 1984. In 1923, the journalist Pierre Labric (who was later to
become mayor of

Montmartre) rode a bicycle down from the first level; some accounts
say he rode down the stairs, others suggest the exterior of one of the
tower’s four legs which slope outward.
Politics have also played a role in its life. During World War II,
the Germans hung a sign on it that read: “Deutschland Siegt Auf Allen
Fronten” (“Germany is victorious on all fronts”). In 1958, a few months
before Fidel Castro’s rise to power, Cuban revolutionaries hung their
red-and-black flag from the first level, and, in 1979, an American from
Greenpeace hung one that read: “Save the Seals”. In 1989, the Tower
celebrated its centennial with music and fireworks (the show lasted 89
minutes).
