X-Ponts
The ''Corps des Ingénieurs des Ponts, des Eaux et des Forêts'' (, in English "Corps of the Engineers of Bridges, Waters and Forests") is a technical Grand Corps of the French State ( grand corps de l'État). Its members, called ''ingénieurs des ponts, des eaux et des forêts'' (nicknamed ''IPEF''), are senior civil servants and top-level engineers, mainly employed by the French Ministry of Ecological Transition and by the French Ministry of Agriculture, but they can also work for every French Ministries, public establishments, or public compagnies. Thanks to its history and its selective recruitment policy, the ''Corps des IPEF'' enjoys considerable prestige within France's senior civil services, as the ''Corps des mines'' and the ''Corps de l'armement''. Recruitment and training Most of the ''IPEF'' are recruited from École polytechnique (around 50%), where they are selected based on their final ranking, and there exist several competitive entrance exams for former students ...

Augustin-Louis Cauchy
Baron Augustin-Louis Cauchy ( , , ; ; 21 August 1789 – 23 May 1857) was a French mathematician, engineer, and physicist. He was one of the first to rigorously state and prove the key theorems of calculus (thereby creating real analysis), pioneered the field complex analysis, and the study of permutation groups in abstract algebra. Cauchy also contributed to a number of topics in mathematical physics, notably continuum mechanics. A profound mathematician, Cauchy had a great influence over his contemporaries and successors; Hans Freudenthal stated: : "More concepts and theorems have been named for Cauchy than for any other mathematician (in elasticity alone there are sixteen concepts and theorems named for Cauchy)." Cauchy was a prolific worker; he wrote approximately eight hundred research articles and five complete textbooks on a variety of topics in the fields of mathematics and mathematical physics.

Charles Joseph Minard (; ; 27 March 1781 – 24 October 1870) was a French civil engineer recognized for his significant contribution in the field of information graphics in civil engineering and statistics. Minard was, among other things, noted for his representation of numerical data on geographic maps, especially his flow maps. Early life Minard was born in Dijon in the Saint Michel parish. He was the son of Pierre Étienne Minard and Bénigne Boiteux. His father was a clerk of the court and an officer of the secondary school. Minard was baptized at Saint Michel on the day of his birth. From Posted by Edward Tufte. He was an intelligent child and his father encouraged him to study at an early age. At age four he learned to read and write, and when he was six his father enrolled him in an elementary course in anatomy. He completed his fourth year of study at the secondary school at Dijon early, and then applied himself to studying Latin, literature, and physical and math scie ...

Pierre Méchain
Pierre François André Méchain (; 16 August 1744 – 20 September 1804) was a French astronomer and surveyor who, with Charles Messier, was a major contributor to the early study of deep-sky objects and comets. Life Pierre Méchain was born in Laon in northern France, the son of the ceiling designer and plasterer Pierre François Méchain and Marie–Marguerite Roze. He displayed mental gifts in mathematics and physics but had to give up his studies for lack of money. However, his talents in astronomy were noticed by Jérôme Lalande, for whom he became a friend and proof-reader of the second edition of his book "L'Astronomie". Lalande then secured a position for him as assistant hydrographer with the Naval Depot of Maps and Charts at Versailles, where he worked through the 1770s engaged in hydrographic work and coastline surveying. It was during this time—approximately 1774—that he met Charles Messier, and apparently, they became friends. In the same year, he also p ...

Étienne-Louis Malus
Étienne-Louis Malus (; ; 23 July 1775 – 23 February 1812) was a French officer, engineer, physicist, and mathematician. Malus was born in Paris, France and studied at the military engineering school at Mezires where he was taught by Gaspard Monge. He participated in Napoleon's expedition into Egypt (1798 to 1801). He was also a member of the mathematics section of the Institut d'Égypte. Malus became a member of the Académie des Sciences in 1810. In 1810 the Royal Society of London awarded him the Rumford Medal. His mathematical work was almost entirely concerned with the study of light. He studied geometric systems called ''ray systems'', closely connected to Julius Plücker's '' line geometry''. He conducted experiments to verify Christiaan Huygens's theories of light and rewrote the theory in analytical form. His discovery of the polarization of light by reflection was published in 1809 and his theory of double refraction of light in crystals, in 1810. Malus at ...

Pierre-Simon Girard
Pierre-Simon Girard (4 November 1765 – 30 November 1836) was a French mathematician and engineer, who worked on fluid mechanics. Girard was born in Caen. A prodigy who invented a water turbine at the age of ten, he worked as an engineer at the École Nationale des Ponts et Chaussées. He was in charge of planning and construction of the Amiens canal and the Ourcq canal. He collaborated with Gaspard de Prony on the ''Dictionnaire des Ponts et Chaussées'' (Dictionary of Bridges and Highways, 1787). He wrote on fluids, and in 1798 he published a monograph, ''Traité analytique de la résistance des solides'' on beam theory, including possibly its first history, within the topic of strength of materials. The complicated beam equations were not of practical much use, since he applied Euler's non-linear theory. In 1799, he and other engineers and scientists accompanied Napoleon on his expedition to Egypt. He died in Paris, aged 71. Important works The 1798 monograph ''Trait ...
