Georges Henri Joseph Édouard Lemaître ( lə-MET-rə; French: [ʒɔʁʒ ləmɛːtʁ] ; 17 July 1894 – 20 June 1966) was a Belgian Catholic priest, theoretical physicist, mathematician, astronomer, and professor of physics at the Catholic University of Louvain. He was the first to theorize that the recession of nearby galaxies can be explained by an expanding universe, which was observationally confirmed soon afterwards by Edwin Hubble. He first derived "Hubble's law", now called the Hubble–Lemaître law by the IAU, and published the first estimation of the Hubble constant in 1927, two years before Hubble's article. Lemaître also proposed the "Big Bang theory" of the origin of the universe, calling it the "hypothesis of the primeval atom", and later calling it "the beginning of the world".

Kurt Gerstein (11 August 1905 – 25 July 1945) was a German SS officer and head of technical disinfection services of the Hygiene-Institut der Waffen-SS (Institute for Hygiene of the Waffen-SS). After witnessing mass murders in the Belzec and Treblinka Nazi extermination camps, Gerstein gave a detailed report to Swedish diplomat Göran von Otter, as well as to Swiss diplomats, members of the Roman Catholic Church with contacts to Pope Pius XII, and to the Dutch government-in-exile, in an effort to inform the international community about the Holocaust as it was happening. In 1945, following his surrender, he wrote the Gerstein Report covering his experience of the Holocaust. He died of an alleged suicide while in French custody.

Pierre-Émile Martin (French: [pjɛʁ emil maʁtɛ̃]; 18 August 1824, Bourges, Cher – 23 May 1915, Fourchambault) was a French industrial engineer. He applied the principle of recovery of the hot gas in an open hearth furnace, a process invented by Carl Wilhelm Siemens.
In 1865, based on the Siemens process, he implemented the process which bears his name for producing steel in a hearth by remelting scrap steel with the addition of cast iron for the dilution of impurities.
His work earned him the award of the Bessemer Gold Medal of the Iron and Steel Institute in 1915 and of the French nation (knight in 1878 then Officer of the Legion of Honour in 1910).

A native of Terre Haute, Indiana, Stuart E. Dreyfus is professor emeritus at University of California, Berkeley in the Industrial Engineering and Operations Research Department. While at the Rand Corporation he was a programmer of the JOHNNIAC computer. While at Rand he coauthored Applied Dynamic Programming with Richard Bellman. Following that work, he was encouraged to pursue a Ph.D. which he completed in applied mathematics at Harvard University in 1964, on the calculus of variations. In 1962, Dreyfus simplified the Dynamic Programming-based derivation of backpropagation (due to Henry J. Kelley and Arthur E. Bryson) using only the chain rule. He also coauthored Mind Over Machine with his brother Hubert Dreyfus in 1986.

Léon Levavasseur (8 January 1863 – 26 February 1922) was a French powerplant engineer, aircraft designer and inventor. His innovations included the V8 engine, direct fuel injection, and liquid engine cooling. Primarily associated with the Antoinette company, he continued to experiment with aircraft design after the company went bankrupt.
