Félix Legueu (12 August 1863 – 2 October 1939) was a French urologist and gynecologist born in Angers.

Maurice Leblanc (1857 – 1923) was a French engineer and industrialist.
Born in Paris, Leblanc worked primarily in improving induction motors and alternators, where he invented the damper winding. He also invented an improved vacuum pump and worked in the area of refrigeration.
The December 1, 1880 French publication "La Lumière électrique", published an article by Leblanc entitled "Etude sur la transmission électrique des impressions lumineuses". In this article Leblanc outlined five functions required for a television system.

a transducer to convert light into electricity
a scanner to break up a picture into its constituent parts
a method of synchronising the receiver and the transmitter
a means of converting electrical signals back into light
a screen for viewing the imageLeblanc was awarded the Prix Poncelet for 1913 by the French Academy of Sciences.

Étienne-Ossian Henry (27 November 1798 in Paris – 26 August 1873) was a French chemist, son of Noël-Étienne Henry (1769–1832), and trained by his father, who was director of the Central Pharmacy of the Parisian hospitals and professor in the School of Pharmacy. In 1824, he became director of the chemical laboratory of the Academy of Medicine. He discovered sinapin and studied mineral waters, the milk of various animals, nicotine, and tannin. In 1827, with Auguste-Arthur Plisson, who had studied under his father, he discovered aspartic acid.In 1845, he invented the first true burette for titration, which is a widely used device in analytical chemistry and related fields.His son was Emmanuel-Ossian Henry (1826-1867).

Maurice Théodore Adolphe Hamy (31 October 1861, Boulogne-sur-Mer – 9 April 1936, Paris) was a French astronomer.
He obtained in 1887 a doctorate from the Faculté des sciences de Paris with dissertation Étude sur la figure des corps célestes. In the 1890s he applied his method of interference fringes to an analysis of errors made in astronomical observations using meridian circles. He used his interference method to confirm Barnard's measurement of the apparent diameter of Venus. Hamy participated in the creation of l'Institut d'optique théorique et appliquée (SupOptique).
He won the prix Lalande in 1895. Filling the empty chair created by the death of Jules Janssen, Hamy was elected in 1908 a member of l'Académie des sciences and then in 1928 its president. He was also elected a member of the Bureau des longitudes.
He is a nephew of Ernest Hamy.

Georges-Henri Halphen (French: [ʒɔʀʒ ɑ̃ʁi alfɛn]; 30 October 1844, Rouen – 23 May 1889, Versailles) was a French mathematician. He was known for his work in geometry, particularly in enumerative geometry and the singularity theory of algebraic curves, in algebraic geometry. He also worked on invariant theory and projective differential geometry.

Pierre-Victor or Pierre Victor Galtier ((1846-10-15)15 October 1846 – (1908-04-24)24 April 1908) was a veterinarian and professor at the National Veterinary School of Lyon, specialising in pathology of infectious diseases, health surveillance and commercial and medical legislation. He developed a rabies vaccine which had some experimental success in laboratory animals.

Julian Leopold Ochorowicz (Polish pronunciation: ['juljan lɛˈɔpɔld ɔxɔˈrɔvit͡ʂ]; outside Poland also known as Julien Ochorowitz; Radzymin, 23 February 1850 – 1 May 1917, Warsaw) was a Polish philosopher, psychologist, inventor (precursor of radio and television), poet, publicist, and leading exponent of Polish Positivism.

Joseph Rémi Léopold Delbœuf (30 September 1831, Liège, Belgium – 14 August 1896, Bonn, Germany) was a Belgian experimental psychologist who studied visual illusions including his work on the Delboeuf illusion. He studied and taught philosophy, mathematics, and psychophysics. He published works across a diverse range of subjects including the curative effects of hypnotism.

Gustavo Colonnetti (8 November 1886 – 20 March 1968) was an Italian mathematician and engineer who made important contributions to continuum mechanics and strength of materials. He was a Rector of the Politecnico di Torino and President of CNR (Consiglio Nazionale delle Ricerche). His theories found important applications in modern techniques of construction, such as pre-stressed concrete.He is remembered for Colonnetti's theorem (or Colonnetti's minimum principle) which states that in equilibrium the potential energy function W* is minimized.

Georges Louis Bouligand (13 October 1889 – 12 April 1979) was a French mathematician. He worked in analysis, mechanics, analytical and differential geometry, topology, and mathematical physics. He is known for introducing the concept of paratingent cones and contingent cones.
