Augustin-Louis Cauchy
Pioneer of real and complex analysis, prolific mathematician and engineer.
He was born in 1789 just after the French Revolution began, and his family survived by fleeing to Arcueil.[1] A profound mathematician, Cauchy had a great influence over his contemporaries and successors, as noted by Hans Freudenthal.[2] At 4 a.m. on 23 May 1857, Cauchy died from a bronchial condition after receiving the Last Rites; he was 67 years old.[3][1]

Facts from the source article.
Life and work
Cauchy's father was a high-ranking Parisian police official who lost his position due to the Revolution.[1] On Lagrange's advice, Cauchy enrolled at the École Centrale du Panthéon in 1802, winning many prizes in Latin and the humanities.[1] He returned to Paris in 1812 after becoming ill from overwork and losing interest in engineering.[1] In Turin he accepted a chair of theoretical physics created for him by the King of Sardinia.[4]
From 1833 to 1838 he tutored the exiled Crown Prince Henri d'Artois in Prague, but the prince acquired a lifelong dislike of mathematics.[1] Cauchy returned to Paris in 1838 but could not regain his teaching posts due to his continued refusal of the oath.[1] After Robespierre's execution in 1794, the Cauchy family could safely return to Paris; there, Louis-François Cauchy found a bureaucratic job in 1800 and later, under Napoleon, became Secretary-General of the Senate.[1][2] In 1810, upon completing school, Cauchy took a junior engineering position in Cherbourg, where he was assigned to the Ourcq Canal project and the Saint-Cloud Bridge project.[1]
On April 4, 1818, Cauchy married Aloïse de Bure; their first daughter was born in 1819 and their second in 1823.[5][6]
What the cited sources add
That same source reports that in mechanics, Cauchy replaced the principle of continuity of matter with the notion of continuity of geometrical displacements.[7][8]
