French Roman Catholics

Xavier Dor (30 January 1929 – 4 April 2020) was a French embryologist, known for his activism against abortions.

Roger Henri Auque (11 January 1956 – 8 September 2014) was a French journalist, war correspondent, and diplomat, and Israeli spy. He served as France's Ambassador to Eritrea from 2009 to 2012.

André Bazin (French: [bazɛ̃]; 18 April 1918 – 11 November 1958) was a renowned and influential French film critic and film theorist. He started to write about film in 1943 and was a co-founder of the renowned film magazine Cahiers du cinéma in 1951, with Jacques Doniol-Valcroze and Joseph-Marie Lo Duca.
He is notable for arguing that realism is the most important function of cinema. His call for objective reality, deep focus, and lack of montage are linked to his belief that the interpretation of a film or scene should be left to the spectator. This placed him in opposition to film theory of the 1920s and 1930s, which emphasized how the cinema could manipulate reality.

Marcel Dassault (born Marcel Ferdinand Bloch; 23 January 1892 – 17 April 1986) was a French engineer and industrialist who spent his career in aircraft manufacturing.

Charles Pierre Péguy (French: [ʃaʁl peɡi]; 7 January 1873 – 5 September 1914) was a French poet, essayist, and editor. His two main philosophies were socialism and nationalism; by 1908 at the latest, after years of uneasy agnosticism, he had become a believing (but generally non-practicing) Roman Catholic.
From that time, Catholicism strongly influenced his works.

Victor Alexandre Puiseux (French: [pɥizø]; 16 April 1820 – 9 September 1883) was a French mathematician and astronomer. Puiseux series are named after him, as is in part the Bertrand–Diquet–Puiseux theorem. His work on algebraic functions and uniformization makes him a direct precursor of Bernhard Riemann, for what concerns the latter's work on this subject and his introduction of Riemann surfaces. He was also an accomplished amateur mountaineer. A peak in the French alps, which he climbed in 1848, is named after him.
A species of Israeli gecko, Ptyodactylus puiseuxi, is named in his honor.
