Over time, this local name was adopted as a surname. Augustin-Louis Cauchy (1789-1857) is one of the most renowned figures associated with the family name. He was a prominent mathematician and mechanician who made significant contributions to various mathematical fields, including analysis, algebra, and differential equations. His pioneering work in mathematics has left a lasting impact on the discipline, further popularizing and solidifying the Cauchy surname in academic circles.
The last name Cauchy is predominantly found in French-speaking regions due to its origin from the mathematical genius Augustin Louis Cauchy, who was born in Paris, France, in 1789. The distribution of this surname within France reflects a concentration in and around the capital region, with notable presence also observed in Brittany, Normandy, and other areas with historical ties to France. Beyond France, significant numbers of individuals bearing the Cauchy name can be found in various French-speaking countries such as Belgium, Switzerland, Canada, and various African nations that were once French colonies. Additionally, due to immigration and diaspora, the distribution of this surname has expanded to other parts of Europe, North America, South America, Australia, and certain regions of Africa and Asia.

Augustin-Louis Cauchy (1789-1857), born in Paris, France, was a prominent mathematician who significantly contributed to numerous fields such as analysis, algebra, and mathematical physics. He is known for his work on complex functions, the theory of integration, and differential equations, among others. Cauchy's ideas about convergence and continuity laid the groundwork for modern analysis. Moreover, he introduced the concept of the Cauchy sequence in mathematics. Despite living during a time of political turmoil, Cauchy maintained a prolific career as both a military engineer and a mathematician, publishing over 800 mathematical papers. His work continues to influence modern mathematics significantly. Another notable figure with the same surname is Louis-Antoine Gaspard Cauchy (1764-1829), Augustin-Louis' father, who served as a high-ranking military officer and engineer in the French Army during the French Revolution and the Napoleonic Wars.
The Cauchy family originates from Cauchières, Normandy, France, dating back to the Middle Ages. One notable member of the lineage is Augustin-Louis Cauchy (1789-1857), a prominent French mathematician who made significant contributions to numerous fields, including analysis, algebra, mathematics of physics, and infinitesimal calculations. Cauchy's work laid the foundation for modern complex function theory, and his name is still associated with several mathematical concepts, such as Cauchy sequences, Cauchy integral formula, and Cauchy's theorem. The mathematician Augustin-Louis was the grandson of Jean-Baptiste Cauchy (1746-1825), a French military officer who served under Napoleon Bonaparte. The family name Cauchy is believed to derive from the Old French word "cauchee," meaning "a small ditch or moat."
