Sjur Refsdal (30 December 1935 – 29 January 2009) was a Norwegian astrophysicist, born in Oslo. He is best known for his pioneer work on gravitational lensing, including the Chang-Refsdal lens.

Erik Magnus Alfsen (13 May 1930 – 20 November 2019) was a Norwegian mathematician. He is the author of Compact Convex Sets and Boundary Integrals, published in 1971. He was a board member of the Norwegian Research Council for Science and the Humanities (NAVF) for two years, and has also been involved in Nei til Atomvåpen and the Pugwash Conferences. He was a member of the Norwegian Academy of Science and Letters, the Royal Norwegian Society of Sciences and Letters and the Royal Danish Academy of Sciences and Letters.

Víctor Manuel Blanco (March 10, 1918 – March 8, 2011) was a Puerto Rican astronomer who in 1959 discovered Blanco 1, a galactic cluster. Blanco was the second Director of the Cerro Tololo Inter-American Observatory in Chile, which had the largest telescope in the Southern Hemisphere at the time. In 1995, the 4-meter telescope was dedicated in his honor and named the Víctor M. Blanco Telescope; it is also known as the "Blanco 4m."

Pierre Euclide Conner (27 June 1932, Houston, Texas – 3 February 2018, New Orleans, Louisiana) was an American mathematician, who worked on algebraic topology and differential topology (especially cobordism theory).
In 1955 Conner received his Ph.D from Princeton University under Donald Spencer with thesis The Green's and Neumann's Problems for Differential Forms on Riemannian Manifolds. He was a post-doctoral fellow from 1955 to 1957 (and again in 1961–1962) at the Institute for Advanced Study. He was in the 1960s a professor at the University of Virginia, where he collaborated with his colleague Edwin E. Floyd, and then in the 1970s a professor at Louisiana State University.
In 2012 he became a fellow of the American Mathematical Society.

Marguerite Catherine Perey (19 October 1909 – 13 May 1975) was a French physicist and a student of Marie Curie. In 1939, Perey discovered the element francium by purifying samples of lanthanum that contained actinium. In 1962, she was the first woman to be elected to the French Académie des Sciences, an honor denied to her mentor Curie. Perey died of cancer in 1975.

Michel Demazure (French: [dəmazyʁ]; born 2 March 1937) is a French mathematician. He made contributions in the fields of abstract algebra, algebraic geometry, and computer vision, and participated in the Nicolas Bourbaki collective. He has also been president of the French Mathematical Society and directed two French science museums.

Pierre Aigrain (28 September 1924 – 30 October 2002) was a French physicist and Secretary of Research in the French Academy of Sciences.

René Adolphe Schwaller de Lubicz (December 30, 1887 – December 7, 1961), born René Adolphe Schwaller in Alsace-Lorraine, was a French Egyptologist and mystic who popularized the idea of sacred geometry in ancient Egypt during his study of the art and architecture of the Temple of Luxor in Egypt, and his subsequent book The Temple In Man.

Édouard Séguin (January 20, 1812 – October 28, 1880) was a French physician and educationist born in Clamecy, Nièvre. He is remembered for his work with children having cognitive impairments in France and the United States.

Jean-Victor Poncelet (French pronunciation: [ʒɑ̃ viktɔʁ pɔ̃slɛ]; 1 July 1788 – 22 December 1867) was a French engineer and mathematician who served most notably as the Commanding General of the École Polytechnique. He is considered a reviver of projective geometry, and his work Traité des propriétés projectives des figures is considered the first definitive text on the subject since Gérard Desargues' work on it in the 17th century. He later wrote an introduction to it: Applications d'analyse et de géométrie.As a mathematician, his most notable work was in projective geometry, although an early collaboration with Charles Julien Brianchon provided a significant contribution to Feuerbach's theorem. He also made discoveries about projective harmonic conjugates; relating these to the poles and polar lines associated with conic sections. He developed the concept of parallel lines meeting at a point at infinity and defined the circular points at infinity that are on every circle of the plane. These discoveries led to the principle of duality, and the principle of continuity and also aided in the development of complex numbers.As a military engineer, he served in Napoleon's campaign against the Russian Empire in 1812, in which he was captured and held prisoner until 1814. Later, he served as a professor of mechanics at the École d'application in his home town of Metz, during which time he published Introduction à la mécanique industrielle, a work he is famous for, and improved the design of turbines and water wheels. In 1837, a tenured 'Chaire de mécanique physique et expérimentale' was specially created for him at the Sorbonne (the University of Paris). In 1848, he became the commanding general of his alma mater, the École Polytechnique. He is honoured by having his name listed among notable French engineers and scientists displayed around the first stage of the Eiffel tower.
