Antoine André Louis Reynaud (born September 12, 1771 in Paris , † February 24, 1844 there ) was a French mathematician.

Reynaud was the son of a lawyer in the Parliament of Paris. As a schoolboy he wrote several plays. He took an active part in the French Revolution, became a captain in the Régiment d'Elèves (pupil and student regiment) in 1790 and joined the National Guard in 1792. However, under pressure from the family, he had to give up his military career and became an accountant, but was drawn to mathematics. In 1796 he gave up his profession after four years and began studying at the École Polytechnique . In 1798 he graduated from the top of his class and was assigned to the Corps des Ponts et Chaussés, but was allowed to continue studying mathematics at the École Polytechnique. In 1800 he became a teacher at a preparatory school for the École Polytechnique (without salary), taught at a lyceum and in 1804 became a teacher at the École Polytechnique, where he was examinator in 1809. From 1808 to 1811 he was assistant to Gaspard de Prony in his mechanics lectures and from 1812 to 1814 he held the analysis lecture as the successor to Louis Poinsot (his successor was Augustin-Louis Cauchy in 1815 ). From 1814 onwards he was politically on the side of King Louis XVIII. Most recently he taught at the Naval School in Brest .

In 1806 he was in charge of the geodetic survey of France.

He is known as a successful author of textbooks, including his adaptation of the arithmetic textbook by Étienne Bézout , which had over 26 editions and contains many original contributions by Reynaud. He is also known for a trigonometry textbook with logarithm tables based on Jérôme de Lalande (whose logarithm and sine tables he also published separately). In this context he was one of the first to systematically analyze algorithms (such as the Euclidean algorithm ).

He was a Knight of the Legion of Honor .
