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

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.

François Cyrille Grand'Eury (9 March 1839, Houdreville – 22 July 1917, Malzéville) was a French geologist, paleontologist and mathematics teacher.
He studied at the École Loritz in Nancy and at the École des mines in Saint-Étienne, and later worked as a mining engineer in Roche-la-Molière. From 1863 to 1899 he taught classes in mathematics at the École des mines in Saint-Étienne, where in 1883 he received the title of professor.From 1877 he was a member of the Société géologique de France and in 1885 was elected a correspondent member of the Académie des Sciences.He is remembered for his stratigraphic research of coal fields and for his investigations involving the formation of coal. He is credited with establishing the chronological succession of floras associated with the coal seams of the Stephanian stage (named after the development of this stage at Saint-Étienne). He conducted exhaustive studies of coal flora (Cordaites, Calamites, et al), and in 1877 described the genus Tubiculites.

Lucien Godeaux (1887–1975) was a prolific Belgian mathematician. His total of more than 1000 papers and books, 669 of which are found in Mathematical Reviews, made him one of the most published mathematicians. He was the sole author of all but one of his papers.He is best remembered for work in algebraic geometry. From Liège, he was attracted to the work of the Italian school of algebraic geometry by the work of one of its masters, Federigo Enriques. Godeaux went to Bologna to study with him. The Godeaux surface is a construction of a special type, which has subsequently been much studied.
Since 2007, the Belgian Mathematical Society (BMS) is organising a "Godeaux lecture" in his memory.

Corrado Gini (23 May 1884 – 13 March 1965) was an Italian statistician, demographer and sociologist who developed the Gini coefficient, a measure of the income inequality in a society. Gini was a proponent of organicism and applied it to nations. Gini was a eugenicist, and prior to and during World War II, he was an advocate of Italian Fascism. Following the war, he founded the Italian Unionist Movement, which advocated for the annexation of Italy by the United States.

Louis Fabry was a French astronomer who was born in Marseille, April 20, 1862, and died in Les Lecques, January 26, 1939.

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.

Gustav Doetsch (29 November 1892 – 9 June 1977) was a German mathematician, aviation researcher, decorated war veteran, and Nazi supporter.
