Jacques Raymond Brascassat (August 30, 1804 – February 28, 1867) was a famous French painter noted for his landscapes, and in particular his animal paintings.

August Friedrich Leopold Weismann FRS (For), HonFRSE, LLD (17 January 1834 – 5 November 1914) was a German evolutionary biologist. Fellow German Ernst Mayr ranked him as the second most notable evolutionary theorist of the 19th century, after Charles Darwin. Weismann became the Director of the Zoological Institute and the first Professor of Zoology at Freiburg.
His main contribution involved germ plasm theory, at one time also known as Weismannism, according to which inheritance (in a multicellular animal) only takes place by means of the germ cells—the gametes such as egg cells and sperm cells. Other cells of the body—somatic cells—do not function as agents of heredity. The effect is one-way: germ cells produce somatic cells and are not affected by anything the somatic cells learn or therefore any ability an individual acquires during its life. Genetic information cannot pass from soma to germ plasm and on to the next generation. Biologists refer to this concept as the Weismann barrier. This idea, if true, rules out the inheritance of acquired characteristics as proposed by Jean-Baptiste Lamarck. However, a careful reading of Weismann's work over the span of his entire career shows that he had more nuanced views, insisting, like Darwin, that a variable environment was necessary to cause variation in the hereditary material.The idea of the Weismann barrier is central to the modern synthesis of the early 20th century, though scholars do not express it today in the same terms. In Weismann's opinion the largely random process of mutation, which must occur in the gametes (or stem cells that make them) is the only source of change for natural selection to work on. Weismann became one of the first biologists to deny Lamarckism entirely. Weismann's ideas preceded the rediscovery of Gregor Mendel's work, and though Weismann was cagey about accepting Mendelism, younger workers soon made the connection.
Weismann is much admired today. Ernst Mayr judged him to be the most important evolutionary thinker between Darwin and the evolutionary synthesis around 1930–1940, and "one of the great biologists of all time".

François-Marie Raoult (; 10 May 1830 – 1 April 1901) was a French chemist who conducted research into the behavior of solutions, especially their physical properties.

Adolphe Niel (4 October 1802 – 13 August 1869) was a French Army general and statesman.
He was born at Muret, Haute-Garonne and entered the École Polytechnique in 1821. Niel entered the engineer school at Metz, became lieutenant in the Engineers Corps in 1827, and captain in 1833. He fought in the French conquest of Algeria, participating in the storming of Constantine. There Niel led the engineer detachment with one of the storming parties, and his conduct gained for him the rank of chef de bataillon in 1837. Niel was promoted to lieutenant colonel in 1840 and to colonel in 1846. His next war service was as chief of staff to General Vaillant during the 1849 siege of Rome, after which he was made general of brigade and director of engineer services at headquarters.In 1851, Niel became a member of the Committee of Fortifications. He became a member of the council of state in 1852 and in 1853 was promoted to general of division. In the first part of the Crimean War, Niel was employed in the expedition to the Baltic Sea and directed engineering operations against Bomarsund. Early in 1855 Niel was sent to the Crimea, where he succeeded General Michel Bizot as chief of engineers. For some years Niel had been the most trusted military adviser of Napoleon III, and he was now empowered to advise the generals on the spot in accordance with the wishes of the sovereign and the home government.Niel managed to carry out this delicate and difficult task with as much success as could be expected, and he directed siege operations at the Battle of Malakoff. His reward was the grand cross of the Légion d'honneur. From 1855 to 1859 Niel was employed at headquarters and also served in the French Senate. In the war against the Austrians, Niel commanded the IV Corps and took part in the Battle of Magenta and the Battle of Solferino. Niel was made a marshal of France on the field at Solferino.After he served for some years in a home command, Niel became minister of war and held the position from 1867 to 1869. In this capacity he drafted and began to carry out a far-reaching scheme of army reform, based on universal service and the automatic creation of large reserves which needed only time to mature. Under his system, those men who had purchased exemption from conscription into the army would nonetheless be called up into a new service, the Garde Mobile. He also was able to rearm the whole of the army with the chassepot rifle, but not the Garde Mobile. He did not live to complete the development of his system.Niel died in Paris during an operation for a bladder stone, and a year later the Franco-Prussian War destroyed the old imperial army upon which the new formations were to have been grafted.

Félix Pyat (4 October 1810 – 3 August 1889) was a French socialist journalist, playwright, politician and a leading figure of the Paris Commune.

François Auguste Ferdinand Mariette (11 February 1821 – 18 January 1881) was a French scholar, archaeologist and Egyptologist, and the founder of the Egyptian Department of Antiquities, the forerunner of the Supreme Council of Antiquities.

Angelo Mai (Latin Angelus Maius; 7 March 1782 – 8 September 1854) was an Italian Cardinal and philologist. He won a European reputation for publishing for the first time a series of previously unknown ancient texts. These he was able to discover and publish, first while in charge of the Ambrosian Library in Milan and then in the same role at the Vatican Library. The texts were often in parchment manuscripts that had been washed off and reused; he was able to read the lower text using chemicals. In particular he was able to locate a substantial portion of the much sought-after De republica of Cicero and the complete works of Virgilius Maro Grammaticus.

Gilles Ménage (French: [menaʒ]; 15 August 1613 – 23 July 1692) was a French scholar.

Charles Martial Allemand Lavigerie, M. Afr. (31 October 1825 – 26 November 1892) was a French Catholic cardinal, Archbishop of Carthage and Algiers and Primate of Africa. He also founded the White Fathers.
A priest who became a bishop in France, Lavigerie established French Catholic missions and missionary orders to work across Africa. Lavigerie promoted Catholicism among the peoples of North Africa, as well as the Black natives further south. He was equally ardent to transform them into French subjects.
He crusaded against the slave trade, and he founded the order of priests called the White Fathers, so named for their white cassocks and red fezzes. He also established similar orders of brothers and nuns. He sent his missionaries to the Sahara, Sudan, Tunisia, and Tripolitania. His efforts were supported by the Pope and the German Chancellor Otto von Bismarck.
Although anti-clericalism was a major issue in France, the secular leader Léon Gambetta proclaimed, "Anti-clericalism is not an article for export", and he supported Lavigerie's work.Lavigerie died in 1892 at the age of 67.

Albert Auguste Cochon de Lapparent (30 December 1839 – 5 May 1908) was a French geologist.
