Léon Labbé (29 September 1832 – 21 March 1916) was a French surgeon and politician who was born in the village of Le Merlerault in the department of Orne. He was an uncle to physician Charles Labbé (1851–1889), who first described the inferior anastomotic vein ("vein of Labbé").
From 1856 to 1860 Labbé was a hospital intern in Paris, and in 1861 earned his medical doctorate. Afterwards, he was a surgeon at several hospitals in Paris, including the Hôpital Beaujon, where he was chief-surgeon for many years. In 1879 he became a member of the Académie de Médecine.
In 1892 he was elected to the Senate representing the department of Orne. In this role, he introduced various laws of interest to the medical community, including the 1914 Loi Labbé (Labbé Law), legislation that provided compulsory anti-typhoid vaccinations for French soldiers.

Marie Adolphe Carnot (27 January 1839 – 20 June 1920) was a French chemist, mining engineer and politician. He came from a distinguished family: his father, Hippolyte Carnot, and brother, Marie François Sadi Carnot, were politicians, the latter becoming President of the third French Republic.
He was born in Paris and studied at the École Polytechnique and the École des Mines. He became a member of the Corps des mines, and from 1864 to 1867, served as a mining engineer in Limoges. From 1868 to 1877 he was a professor of preparatory courses and general chemistry at the École des Mines in Paris, where from 1877 to 1901, he worked as a professor of analytical chemistry.In 1881 he was appointed Chief Engineer of Mines, and in 1894, was named Inspector General of Mines. He became director of the École des Mines in 1901, a post he held until 1907. Aside from administrative work and teaching and training many engineers, he wrote a treatise on the chemical analysis of minerals (Traité d'analyse des substances minérales, published 1898) and pursued research. The uranium ore carnotite is named after him.He was honoured with membership of the Académie d'Agriculture (1884) and Académie des sciences (1895), and was made a Commander of the Légion d'honneur (1903). He also pursued a political career.

René Waldeck-Rousseau (27 April 1809 Avranches, Manche – 17 February 1882 Nantes, Loire-Atlantique) was a French politician, father of Pierre Waldeck-Rousseau who was a statesman during the Third Republic.
During the 1848 Revolution, he was elected as a Republican deputy of Loire-Inférieure to the Constituent Assembly of April 1848 to May 1849. He then became mayor of Nantes, from 1870 to 1871 and a second time from 1872 to 1874.
With Jules Simon, Louis Blanc and others he sat on the commission appointed to inquire into the labour question during the Second Republic, making many important proposals, one of which, for the establishment of national banks, was partially realized in 1850. After the election of Louis Napoleon Bonaparte to the presidency he returned to his practice at the bar, and for some time after the coup d'état was in hiding to escape arrest.
He came back to political life in the crisis of 1870, when he became mayor of Nantes in August and took part to the proclamation of the Third Republic there on September 4. He shortly afterwards resigned municipal office in consequence of differences with his colleagues on the education question.

He worked as a designer in Paris, and became prominent as a member of the municipal council of Paris; rousing much angry discussion by a proposal to rename the Parisian streets which bore saints' names.In 1887 he became president of the council.

His wife, Amélie de Wailly (b. 1853), was well known as a writer of light verse and of some charming children's books.Mesureur was a prominent freemason.
