Jean-Victor Poncelet (French pronunciation: [ʒɑ̃ viktɔʁ pɔ̃slɛ]; 1 July 1788 – 22 December 1867) was a French engineer and mathematician who served most notably as the Commanding General of the École Polytechnique. He is considered a reviver of projective geometry, and his work Traité des propriétés projectives des figures is considered the first definitive text on the subject since Gérard Desargues' work on it in the 17th century. He later wrote an introduction to it: Applications d'analyse et de géométrie.As a mathematician, his most notable work was in projective geometry, although an early collaboration with Charles Julien Brianchon provided a significant contribution to Feuerbach's theorem. He also made discoveries about projective harmonic conjugates; relating these to the poles and polar lines associated with conic sections. He developed the concept of parallel lines meeting at a point at infinity and defined the circular points at infinity that are on every circle of the plane. These discoveries led to the principle of duality, and the principle of continuity and also aided in the development of complex numbers.As a military engineer, he served in Napoleon's campaign against the Russian Empire in 1812, in which he was captured and held prisoner until 1814. Later, he served as a professor of mechanics at the École d'application in his home town of Metz, during which time he published Introduction à la mécanique industrielle, a work he is famous for, and improved the design of turbines and water wheels. In 1837, a tenured 'Chaire de mécanique physique et expérimentale' was specially created for him at the Sorbonne (the University of Paris). In 1848, he became the commanding general of his alma mater, the École Polytechnique. He is honoured by having his name listed among notable French engineers and scientists displayed around the first stage of the Eiffel tower.

General Antoine Jules Joseph Huré (11 February 1873 – December 1949) was a French army officer and engineer noted for his service in Morocco. Huré joined the army as a volunteer in 1893 and after training at the École Polytechnique and École d'Application de l'Artillerie et du Génie he was commissioned into the 3rd Regiment of Engineers. He spent a number of years with his regiment and on staff appointments in France before transferring to Algeria first with the 19th Army Corps, and then the 15th Army Corps. In 1912 Huré transferred to the general staff in eastern Morocco and earned the Colonial Medal.
Huré was recalled to France at the start of the First World War and was shot in the chest whilst serving with the 1st Moroccan Infantry Division, being mentioned in dispatches for continuing with his duties despite his wound. He was posted back to Morocco in 1916 to become military commander of the Fes region. In January 1919 he took over command of French operations against the uprising led by Sidi Mhand n'Ifrutant in the Tafilalt after General Joseph-François Poeymirau was wounded. Huré suppressed the uprising within a month. In April 1919 he led a column to the relief of a French garrison at Aïn Médiouna which had put up a defence against a Moroccan force twenty times their number for four days during another uprising against French rule. Huré then launched further operations that stabilised the military situation in the area within the month. In July he was appointed commander of French troops in Southern Morocco.
Huré eventually reached the rank of général de division and became supreme commander of all French troops in Morocco. Under his supervision the country was finally pacified in 1934. He returned to France in 1935 to serve on the Supreme Council of War and was later made inspector general of engineers. He wrote two books on military history, including one on the pacification of Morocco that was published after his death. Huré was rewarded for his work by appointment as Grand Cross of the Legion of Honour and as Commander of the Order of Ouissam Alaouite.

Charles Auguste Frossard (26 April 1807 – 25 August 1875) was a French general.
He entered the army from the École polytechnique in 1827, being posted to the engineers. He took part in the siege of Rome in 1849 and in that of Sevastopol in 1855, after which he was promoted general of brigade. Four years later as general of division, and chief of engineers in the Italian campaign, he attracted the particular notice of the emperor Napoleon III, who made him in 1867 chief of his military household and governor to the prince imperial.He was one of the superior military authorities who in this period 1866-1870 foresaw and endeavoured to prepare for the inevitable war with Germany, and at the outbreak of the Franco-Prussian War he was given by Napoleon the choice between a corps command and the post of chief engineer at headquarters. He chose the command of the II corps. On 6 August 1870 he held the position of Spicheren against the Germans until the arrival of reinforcements for the latter and the non-appearance of the other French corps compelled him to retire. After this he took part in the battles around Metz, where he distinguished himself at Mars-la-Tour and Gravelotte. He then participated with his corps in the Siege of Metz and was involved in the surrender of Bazaine's army. General Frossard published in 1872 a Rapport sur les operations du 2 corps. He died at Cháteau-Villain (Haute-Marne).

Maurice Gross (born 21 July 1934 in Sedan, Ardennes department; died 8 December 2001 in Paris) was a French linguist and scholar of Romance languages. Beginning in the late 1960s he developed Lexicon-Grammar, a method of formal description of languages with practical applications.
