Augustin-Louis Cauchy born: August 21, 1789 in Paris died: May 23, 1857 outside Paris Modern mathematics is indebted to Cauchy for two of its major interests, each of which marks a sharp break with the mathematics of the eighteenth century. The first was the introduction of rigor into mathematical analysis. The second thing of fundamental importance was on the opposite side the combinatorial. (E.T. Bell) Brilliant. Prolific. Pious. Stubborn. Based calculus on the concept of limit. Cauchy's root and ratio tests for convergence of series, Cauchy's inequality, Cauchy's integral formula and theorem, Cauchy product, Cauchy-Riemann differential equations. His ideas developed into the theory of finite groups. At 24, Cauchy returned to Paris. His mathematical researches at Cherbourg had already attracted the attention of France's top mathematicians. At 26, he proved a conjecture of Fermat which had stumped Euler and Gauss: "Every positive integer is the sum of 3 triangular numbers, 4 square numbers, 5 pentagonal numbers, ... ". He lectured on analysis at the Polytechnique and became a professor at the Sorbonne. By 27, he was among the best living mathematicians and had started work on functions of a complex variable. All 300 pages of this research was published 11 years later. During his incredible mathematical rise he also found time to marry, apparently very happily. He remained married for 40 years and had 2 daughters whom he educated at home in the way he had been educated by his father.

A short sojourn at Freiburg in Switzerland was followed by his appointment in 1831 to the newly-created chair of mathematical physics at the University of Turin. In 1833 the deposed King Charles X of 1851, Cauchy and Arago were exempted from it. A profound mathematician, Cauchy exercised by his clear and rigorous methods a great influence over his contemporaries and successors. His writings cover the entire range of mathematics and mathematical physics. The genius of Cauchy was promised in his simple solution of the problem of Apollonius, i.e. to describe a circle touching three given circles, which he discovered in 1805, his generalization of Leonhard Euler 's theorem on polyhedra in 1811, and in several other elegant problems. More important is his memoir on wave-propagation which obtained the Grand Prix of the Institut in 1816. His greatest contributions to mathematical science are enveloped in the rigorous methods which he introduced. These are mainly embodied in his three great treatises

Augustin-Louis Cauchy (1789-1857) was born in Paris, France, and was educated by his father during his early hears. He then studied at the Ecole Centrale du Pantheon, where he did exceedingly well in ancient classical studies. He entered the Polytechnic school in 1805 and the Ecole des Ponts et Chausses in 1807. He became an engineer in 1810. A few years later, he gave up that nonsense and took up pure science. From that time, he developed many new ideas. He made contributions to the theory of light and mechanics, he made great strides in complex analysis, and founded calculus in its modern form. (Struik 1987 220).

Cauchy's Mathematical Accomplishments Cauchy's Criterion for Convergence Bibliography Back to the front page Augustin-Louis Cauchy - Cauchy's Life Somsack Chaitesipaseut Augustin-Louis Cauchy was one of the greatest mathematicians during the nineteenth century. In fact, there are sixteen concepts and theorems named after him, more than any other mathematician. His life began in Paris, France on August 21, 1789, and ended at Sceaux, France on May 22, 1857. His father, Luois-Francois, and his mother, Marie-Madeleine Desestre, provided him and his siblings a comfortable life [Freudenthal, p. 131]. Cauchy was exposed to famous scientists as a child. The Cauchy family once had Laplace and Berthollet as neighbors, and his father even knew Lagrange. In fact, Lagrange had foreseen Augustin's scientific greatness when he was a child by warning his father to not show him any mathematical text before he was seventeen years old [Freudenthal, p. 131]. After the July Revolution of 1830, Cauchy lost most of his positions at the instistutes because he refused to take the oath of allegiance to the new king, Louis-Philippe, and decided to leave France. It was in 1833 that the ousted king of France, Charles X, called Cauchy to Prague to educate his son, who would later be the Duke of Chambord. It was not explained why, but Cauchy's wife joined him in Prague one year later [Freudenthal, p. 132]. Cauchy went back to Paris in 1838 when he finished his work with Charles X in Prague, and resumed his involvement with the Academy. At the time, because Cauchy was a mathematician, he was exempted from the oath of allegiance. After the establishment of the Second Republique in 1848, Cauchy resumed his position at the Sorbonne. Cauchy continued with his writings and publications through the remainder of his life [Freudenthal, p. 132].

Augustin-Louis Cauchy (1789-1857) With Lagrange and Gauss the nineteenth-century rigorization of analysis got under way. This work was considerably furthered and strengthened by the great French mathematician Augustin-Louis Cauchy, the most outstanding analyst of the first half of the nineteenth century. Cauchy was born in Paris in 1789 and received his early education from his father. Later, at the Ecole Centrale du Pantheon, he excelled in ancient classical studies. In 1805 he entered the Ecole polytechnique and won the admiration of Lagrange. Two years later he enrolled at the Ecole des Ponts et Chaussees, where he prepared himself to be a civil engineer. Under the persuasion of Lagrange, he decided to give up civil engineering in favor of pure science and accepted a teaching post at the Ecole Polytechnique. Cauchy wrote extensively and profoundly in both pure and applied mathematics, and he can probably be ranked next to Euler in volume of output. His collected works contain , in addition to several books, seven hundred and eighty-nine papers, some of which are very extensive works, and fill twenty-four large quarto volumes. This work is of uneven quality, and consequently Cauchy (quite unlike the case of Gauss) has been criticized for overproduction and over hasty composition. A story is told in connection with Cauchy’s prodigious productivity. In 1835 the Academy of Sciences began publishing its Comptes Rendus. So rapidly did Cauchy supply this journal with articles that the Academy became alarmed over the mounting printing bill, and accordingly passed a rule, still in force today, limiting all published papers to maximum length of four pages. Cauchy had to seek other outlets for his longer papers, some of which exceeded a hundred pages.

There things were hard and he wrote in a letter:- We never have more than a half pound of bread - and sometimes not even that. This we supplement with the little supply of hard crackers and rice that we are allotted. They soon returned to Paris and Cauchy's father was active in the education of young Augustin-Louis.
