sandboxes on the scaffold. Although construction involved 300 on-site employees, due to Eiffel's safety precautions and the use of movable gangways, guardrails and screens, only one person died.

=== Inauguration and the 1889 exposition ===

The main structural work was completed at the end of March 1889 and, on 31 March, Eiffel celebrated by leading a group of government officials, accompanied by representatives of the press, to the top of the tower. Because the lifts were not yet in operation, the ascent was made by foot, and took over an hour, with Eiffel stopping frequently to explain various features. Most of the party chose to stop at the lower levels, but a few, including the structural engineer, Émile Nouguier, the head of construction, Jean Compagnon, the President of the City Council, and reporters from Le Figaro and Le Monde Illustré, completed the ascent. At 2:35 pm, Eiffel hoisted a large Tricolour to the accompaniment of a 25-gun salute fired at the first level.
There was still work to be done, particularly on the lifts and facilities, and the tower was not opened to the public until nine days after the opening of the exposition on 6 May; even then, the lifts had not been completed. The tower was an instant success with the public, and nearly 30,000 visitors made the 1,710-step climb to the top before the lifts entered service on 26 May. Tickets cost 2 francs for the first level, 3 for the second, and 5 for the top, with half-price admission on Sundays, and by the end of the exhibition there had been 1,896,987 visitors.
After dark, the tower was lit by hundreds of gas lamps, and a beacon sent out three beams of red, white and blue light. Two searchlights mounted on a circular rail were used to illuminate various buildings of the exposition. The daily opening and closing of the exposition were announced by a cannon at the top.

On the second level, the French newspaper Le Figaro had an office and a printing press, where a special souvenir edition, Le Figaro de la Tour, was made.
At the top, there was a post office where visitors could send letters and postcards as a memento of their visit. Graffitists were also catered for: sheets of paper were mounted on the walls each day for visitors to record their impressions of the tower. Gustave Eiffel described the collection of responses as "truly curious".

Famous visitors to the tower included the Prince of Wales, Sarah Bernhardt, "Buffalo Bill" Cody (his Wild West show was an attraction at the exposition) and Thomas Edison. Eiffel invited Edison to his private apartment at the top of the tower, where Edison presented him with one of his phonographs, a new invention and one of the many highlights of the exposition. Edison signed the guestbook with this message on September 10, 1889: To M Eiffel the Engineer the brave builder of so gigantic and original specimen of modern Engineering from one who has the greatest respect and admiration for all Engineers including the Great Engineer the Bon Dieu, Thomas Edison.
Eiffel made use of his apartment at the top of the tower to carry out meteorological observations, and also used the tower to perform experiments on the action of air resistance on falling bodies.

=== Subsequent events ===

Originally commissioned as a temporary structure for the 1889 Exposition Universelle, Eiffel was slated for dismantling in 1909, at which point ownership would have reverted to the City of Paris. While the original design contest necessitated that the tower be easily disassembled, the structure was spared from scheduled demolition due to its demonstrated utility in early 20th-century scientific and technological advancements, specifically radio telegraphy. Following the expiration of the original concession, the tower was permitted to remain, subsequently becoming an integral part of the International Time Service in 1910.
For the 1900 Exposition Universelle, the lifts in the east and west legs were replaced by lifts running as far as the second level constructed by the French firm Fives-Lille. These had a compensating mechanism to keep the floor level as the angle of ascent changed at the first level, and were driven by a similar hydraulic mechanism as the Otis lifts, although this was situated at the base of the tower. Hydraulic pressure was provided by pressurised accumulators located near this mechanism. At the same time the lift in the north pillar was removed and replaced by a staircase to the first level. The layout of both first and second levels was modified. The original lift in the south pillar was removed 13 years later.

On 19 October 1901, Alberto Santos-Dumont, flying his No.6 airship, won a 100,000-franc prize offered by Henri Deutsch de la Meurthe for the first person to make a flight from St. Cloud to the Eiffel Tower and back in less than half an hour.
From 1910, the astronomical clocks of the Paris Observatory sent the time to sea daily through the Eiffel Tower within a radius of 5 000 km. The development of wireless telegraphy allowed unifying Universal Time. On 9 March 1911, France adopted Greenwich Mean Time by law. However, the law did not refer to Greenwich Prime Meridian, but to the local mean t

The inauguration ceremony was held on March 31, 1889. The US President at the time: Grover Cleveland (his second term was from 1885 to 1889). The French President: Sadi Carnot (in office from 1887 to 1894). Let me quickly verify — Cleveland served as the 22nd and 24th President, and his second term ran from March 4, 1885 to March 4, 1889. So on March 31, 1889 it was still Cleveland. Sadi Carnot took office on December 3, 1887. Both are correct. I'm confident in these facts, but a quick check wouldn't hurt — these are well-established historical facts, so I can answer directly.

=== [5] ASSISTANT TEXT ===
**Inauguration date relied on:** The Eiffel Tower was inaugurated on **31 March 1889**, when Gustave Eiffel led government officials and press representatives to the top and raised the French tricolour with a 25-gun salute (per Wikipedia's "Inauguration and the 1889 exposition" section). Note the tower wasn't opened to the public until 15 May 1889.

**US President on 31 March 1889:** **Grover Cleveland** — he was serving his non-consecutive second term (22nd and then 24th president), which ran from 4 March 1885 to 4 March 1889, so he was still in office at the inauguration.

**French President on 31 March 1889:** **Sadi Carnot**, who served as President of the French Republic from 3 December 1887 until his assassination in 1894.
