Joseph Duval-Jouve (7 August 1810 – 25 August 1883) was a French botanist born in Boissy-Lamberville. He was the father of histologist Mathias-Marie Duval (1844-1907).
He taught classes at the college in Grasse (1832–52), afterwards serving as an academic inspector in Algiers, Strasbourg and Montpellier. A portion of his herbarium was donated to the faculty of sciences at Montpellier.
He specialized in research of the family Poaceae and the genus Equisetum. The plant genus Jouvea is named in his honor. He is the taxonomic authority for the grass genus Loretia.

Frans-H. van den Dungen (1898–1965) was a Belgian scientist and professor at the Universite Libre de Bruxelles. In 1946 he was awarded the Francqui Prize on Exact Sciences.
Among his students was the mathematician Paul Dedecker.

Étienne Marie Justin Victor Delbos (26 September 1862, Figeac – 16 June 1916, Paris) was a Catholic philosopher and historian of philosophy.
Delbos was appointed a lecturer at the Sorbonne in 1902. In 1911 he became a member of the Académie des Sciences Morales et Politiques. He died in July 1916 as a result of an infectious myocarditis brought on by pleurisy. Maurice Blondel, a close friend, wrote an obituary account of Delbos and saw various posthumous publications through the press.He wrote on Spinoza, Nicolas Malebranche and Kant. A series of lectures on post-Kantian philosophy, which Delbos viewed as shaped by contingent psychological and social factors rather than through the unfolding of some internal logic, were published posthumously and later (1942) collected in a single volume.Delbos was the father of the violinist and composer Claire Delbos. In turn, he was the father-in-law of Olivier Messiaen.

Pierre Paul Dehérain (19 April 1830 in Paris – 7 December 1902) was a French plant physiologist and agricultural chemist. He was notably the doctoral advisor of the Nobel Prize winner Henri Moissan.
He served as an assistant at the Conservatoire national des arts et métiers in Paris, then at the age of 26, began work as a professor at the Collège Chaptal. He obtained his LSc degree in 1856 under Edmond Frémy. Later on, he taught classes in agricultural chemistry at the agricultural school in Grignon, and in 1880, became a professor of plant physiology at the Muséum d'Histoire Naturelle. In 1887 he was elected a member of the Académie des sciences.As a plant physiologist, he studied the absorption of carbon dioxide by plants and the effect of artificial light, especially ultraviolet rays, on plants. He showed that plants do not absorb only those minerals that are beneficial, as previously thought, but absorb all of them and then use those that they need – so that consumption regulates absorption. He discovered respiration by plant roots and investigated the effect of different minerals on the growth of fruits. He also studied effect of crop rotation on soil quality.
The plant genus Deherainia from the family Theophrastaceae is named after him.

Jean-Ovide Decroly (Ronse, 23 July 1871 – Uccle, 10 September 1932) was a Belgian teacher and psychologist.
He studied medicine at the University of Ghent, with half a year at the University of Berlin where he studied the action of toxins and antitoxins on general nutrition in 1898. He later worked with (mentally) handicapped children at the neurological clinic in Brussels.
Decroly founded The Hermitage School in 1907. He was a freemason, and a member of the lodge Les Amis Philanthropes of the Grand Orient of Belgium in Brussels. Nowadays the "Ecole Decroly" (based in Uccle, Brussels, a school reaching from kindergarten to baccalaureate) is following his pedagogical approach.

Jean François Chazy (15 August 1882, Villefranche-sur-Saône – 9 March 1955, Paris) was a French mathematician and astronomer.

Marcello Boldrini (9 February 1890, in Matelica – 5 March 1969, in Milan) was an Italian statistician.

Hermann Beitzke (21 June 1875 – 8 June 1953) was a German pathologist born in Tecklenburg, Westphalia.
Beitzke studied medicine at several universities, earning his doctorate in 1899 from the University of Kiel. In 1900-01 he was an assistant at the institute of hygiene in Halle an der Saale, and afterwards worked at the pathology institutes in Göttingen and Berlin. In 1911 he became a professor at the University of Lausanne, and in 1922 relocated to the University of Graz, where he taught classes until 1941.
He specialized in pathological investigations of infectious diseases, in particular tuberculosis studies. He was co-editor of Ergebnisse der gesamten Tuberkuloseforschung, a journal involving tuberculosis research.

Alexandre Edouard Baudrimont (7 May 1806 – 24 January 1880) was a 19th-century French professor of chemistry who published various books connected to the sciences, languages and the Basque Country (in particular Erromintxela):

Dictionnaire de l'industrie manufacturière, commerciale et agricole (1837, Paris)
Recherches anatomiques et physiologiques sur le développement du fœtus: et en particulier sur l'évolution embryonnaire des oiseaux et des batraciens (with Martin Saint-Ange, G.J.) (1846)
Histoire des Basques ou Escualdunais primitifs, restaurée d'après la langue, les caractères ethnologiques et les mœurs des Basques actuels (1854, Paris)
Vocabulaire de la langue des Bohémiens habitant les Pays Basque Français (1862, Bordeaux)In the field of science he is best known for first preparation of Na3P in the mid-19th century by reacting molten sodium with phosphorus pentachloride.

Amedeo Agostini (6 March 1892, in Capugnano di Porretta Terme — 27 June 1958, in Livorno) was an Italian mathematician born in Capugnano di Porretta Terme.
