Jacobi’s Gesammelte Werke, Vol. 4 PDF important concepts such as the Legendre polynomials and Legendre transformation are named after him. Adrien-Marie Legendre was born in Paris on 18 September 1752 to a wealthy family.

Författare: Carl Gustav Jakob Jacobi.

He received his education at the Collège Mazarin in Paris, and defended his thesis in physics and mathematics in 1770. The Académie des sciences made Legendre an adjoint member in 1783 and an associate in 1785. In 1789, he was elected a Fellow of the Royal Society. Legendre lost his private fortune in 1793 during the French Revolution. That year, he also married Marguerite-Claudine Couhin, who helped him put his affairs in order. In 1795, Legendre became one of six members of the mathematics section of the reconstituted Académie des Sciences, renamed the Institut National des Sciences et des Arts.

Later, in 1803, Napoleon reorganized the Institut National, and Legendre became a member of the Geometry section. Legendre died in Paris on 10 January 1833, after a long and painful illness, and Legendre’s widow carefully preserved his belongings to memorialize him. Upon her death in 1856, she was buried next to her husband in the village of Auteuil, where the couple had lived, and left their last country house to the village. Legendre’s name is one of the 72 names inscribed on the Eiffel Tower. Abel’s work on elliptic functions was built on Legendre’s and some of Gauss‘ work in statistics and number theory completed that of Legendre.

His major work is Exercices de Calcul Intégral, published in three volumes in 1811, 1817 and 1819. Legendre symbol is named after him. He is known for the Legendre transformation, which is used to go from the Lagrangian to the Hamiltonian formulation of classical mechanics. Legendre is best known as the author of Éléments de géométrie, which was published in 1794 and was the leading elementary text on the topic for around 100 years. This text greatly rearranged and simplified many of the propositions from Euclid’s Elements to create a more effective textbook. The Moon crater Legendre is named after him.

Main-belt asteroid 26950 Legendre is named after him. Legendre is one of the 72 prominent French scientists who were commemorated on plaques at the first stage of the Eiffel Tower when it first opened. 1784 Recherches sur la figure des Planètes p. 1786 Mémoire sur la manière de distinguer les Maxima des Minima dans le Calcul des Variations p. 1786 Mémoire sur les Intégrations par arcs d’ellipse p. 1786 Second Mémoire sur les Intégrations par arcs d’ellipse p.
