Augustin-Louis Cauchy
modernPhilosophy of Mathematics1789 – 1857
Augustin-Louis Cauchy (1789–1857) was a French mathematician whose rigorous reformulation of calculus and analysis laid the groundwork for modern mathematics. Though primarily a mathematician, his work intersected with philosophy of mathematics, particularly questions about the foundations and epistemological status of geometric and analytic systems. A devout Catholic, he also engaged with questions about the nature of mathematical truth.
