The Eiffel {y'-ful} 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.

At 300 metres (320.75m including antenna), and 7000 tons, it was the world's tallest building until 1930. Other statistics include:

• 2.5 million rivets.
• 300 steel workers, and 2 years (1887-1889) to construct it.
• Sway of at most 12 cm in high winds.
• Height varies up to 15 cm depending on temperature.
• 15,000 iron pieces (excluding rivets).
• 40 tons of paint.
• 1652 steps to the top.

It was almost torn down in 1909, 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.
