Constantin Marie Le Paige (9 March 1852 – 26 January 1929) was a Belgian mathematician.
Born in Liège, Belgium, Le Paige began studying mathematics in 1869 at the University of Liège. After studying analysis under Professor Eugène Charles Catalan, Le Paige became a professor at the Université de Liège in 1882.
While interested in astronomy and the history of mathematics, Le Paige mainly worked on the theory of algebraic form, especially algebraic curves and surfaces and more particularly for his work on the construction of cubic surfaces. Le Paige remained at the university until his retirement in 1922.

Thomas Murray MacRobert (4 April 1884, in Dreghorn, Ayrshire – 1 November 1962, in Glasgow) was a Scottish mathematician. He became professor of mathematics at the University of Glasgow and introduced the MacRobert E function, a generalisation of the generalised hypergeometric series.

Ernest Jean Philippe Fauque de Jonquières (born Carpentras, France 3 July 1820; died Mousans-Sartoux, France 12 August 1901) was a French mathematician and naval officer who made several contributions in geometry.
Jonquières attended the naval school at Brest, and later joined the French Navy. in 1841 he became a lieutenant, and from 1849 to 1850 he served on the staff of the Admiral in Paris. During this time, Jonquières became a close associate of Michel Chasles, whose works he had studied. During his subsequent time at sea, he continued his mathematical studies, and won a part of the Grand Prix of the French Academy of Sciences in 1862.
In 1865, Jonquières became a captain and was sent to Saigon to organize a French agricultural and industrial exhibition. He played an important role in the development of current Vietnam as a French colony. Later, he was head of the local naval depot and its maps and plans. In 1874, Jonquières was made Vice-Admiral. He retired in 1885.

Gerrit van Iterson Jr (Roermond, 19 August 1878 – Wassenaar, 4 January 1972) was a Dutch botanist and professor who developed a mathematical approach to plant growth (phyllotaxis).

Marie Georges Humbert (7 January 1859 Paris, France – 22 January 1921 Paris, France) was a French mathematician who worked on Kummer surfaces and the Appell–Humbert theorem and introduced Humbert surfaces. His son was the mathematician Pierre Humbert. He won the Poncelet Prize of the Académie des Sciences in 1891.
He studied at the École Polytechnique. He was the brother-in-law of Charles Mangin.

John Mackintosh Howie (23 May 1936 – 26 December 2011) was a Scottish mathematician and prominent semigroup theorist.

Charles Henry (1859–1926) was a French librarian and editor. He was born at Bollwiller, Haut-Rhin, and was educated in Paris, where in 1881 he became assistant and afterward librarian in the Sorbonne. As a specialist in the history of mathematics, he was sent to Italy to seek some manuscripts of that nature which the government wished to publish. He edited several works upon kindred subjects, as well as memoirs, letters, and other volumes, and wrote critiques upon the musical theories of Rameau and Wronski. He is also credited with the invention of several ingenious devices and instruments used in psychophysiological laboratories. He published C. Huet's correspondence under the title Un érudit, homme du monde, homme d'église, homme de cour (1880), and he issued also Problèmes de géométrie pratique (1884) and Lettres inédites de Mlle. de Lespinasse à Condorcet et à D'Alembert (1887).Charles Henry, a mathematician, inventor, esthetician, and intimate friend of the Symbolist and anarchist writers Félix Fénéon and Gustave Kahn, met Georges Seurat, Paul Signac and Camille Pissarro during the last Impressionist exhibition in 1886. Henry would take the final step in bringing emotional associational theory into the world of artistic sensation: something that would influence greatly the Neo-Impressionists. Henry and Seurat were in agreement that the basic elements of art—the line, particle of color, like words—could be treated autonomously, each possessing an abstract value independent of one another, if so chose the artist. In 1889 Fénéon noted that Seurat knew that the line, independent of its topographical role, possesses an assessable abstract value, in addition, to the individual pieces of color, and the relation of both to the observer's emotion.
The Neo-Impressionists established what was accepted as an objective scientific basis for their painting in the domain of color. The underlying theory behind Neo-Impressionism would have a lasting effect on the works produced in the coming years by the likes of Robert Delaunay. The Cubists were to do so in both form and dynamics, and the Orphists would do so with color too. The decomposition of spectral light expressed in Neo-Impressionist color theory of Paul Signac and Charles Henry played an important role in the formulation of Orphism. Robert Delaunay, Albert Gleizes, and Gino Severini all knew Henry personally.

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.

Louis Georges Gouy (February 19, 1854 – January 27, 1926) was a French physicist. He is the namesake of the Gouy balance, the Gouy–Chapman electric double layer model (which is a relatively successful albeit limited model that describes the electrical double-layer which finds applications in vast areas of studies from physical chemistry to biophysics) and the Gouy phase.
Gouy was born at Vals-les-Bains, Ardèche in 1854. He became a correspondent of the Académie des sciences in 1901, and a member in 1913.

François Gonnessiat (May 22, 1856 (Nurieux-Volognat)–October 18, 1934) was a French astronomer, observer of comets and discoverer of two minor planets.He worked at the Observatory of Lyon. In 1889 he won the Lalande Prize for astronomy from the French Academy of Sciences; 1901 became director of the Quito (Ecuador) Observatory for the purpose of making geodetic measurements. He became a well known and respected member of the academic scene of the city, where a street is named after him. From 1908 to 1931, he was director of the Algiers Observatory where one of his colleagues was Benjamin Jekhovsky. He was also director of the Quito Astronomical Observatory.The asteroid 1177 Gonnessia was named in his memory (H 109).
