On 4 June 1783, Joseph Michel and Jacques Etienne Montgolfier captured the imagination of the world with their first balloon flight at Cordeliers Square. There were no passengers, but the Regional Council and the whole town population saw the machine go up and stay aloft at 500 meters for ten minutes. The scientific world raced to make use of the Montgolfiers’ discovery, and all accomplishments made since then by aeronauts, aviators, and astronauts can be traced directly to this site.

On 11 July 1962 a station in Pimsleur-Bodou received the first transatlantic transmission of a TV signal from a twin station in Andover, Maine, USA via the TELSTAR satellite. The success of TELSTAR and the earth stations, the first built for active satellite communications, illustrated the potential of a future world-wide satellite system to provide communications between continents.
The Eiffel Tower was built for the International Exhibition of Paris of 1889 commemorating the centenary of the French Revolution. Of the 700 proposals submitted in a design competition, Gustave Eiffel's was unanimously chosen. At 300 meters and 7,000 tons, it was the world's tallest building until 1930.
The elevators ascend and descend within the curved legs of the tower, starting at an angle of 54 degrees from horizontal at the base and leveling out to 78 degrees at the top. The elevator cars are built with seatbacks that rotate to adjust to the varying angle.
Late in life, the renowned structural engineer Gustave Eiffel (1832-1923) embarked on aeronautical research. Reliable data and repeatable research methods were rare in the early 1900s, but Eiffel brought an engineer's discipline to the field. In the process, he produced the most accurate aeronautical data of the time, confirmed a long-held theory about fluid flow that had never been unequivocally proven, and established a laboratory that became a model for future practice.
Inventions credited to the Ecole Nationale des Ponts et Chaussees and its graduates include: prestressed concrete, lighting gas, and the optical lens. The school and its graduates also have been central to research in the diffraction of light, the applications of concrete, and the measurement of the strength of materials.
Antoine-Laurent Lavoisier studied at the Académie des Sciences de l'Institut de France (then "Collège Mazarin") from 1754 to 1761. He was elected to the Royal Academy of Sciences in 1768, where he presented his important studies on oxygen in chemistry. These began with a "pli cacheté" of Nov. 2, 1772, and, after he experimentally proved the chemical composition of water by the quantitative method, culminated in his abandoning of the phlogistic theory in 1785.
