Adrien-Marie Legendre Biography
Birthday: September 18, 1752 (Virgo)
Born In: Paris, France
Adrien-Marie Legendre, a renowned French mathematician holds a distinguished place in the field of mathematics. Having spent his early years in extensive research work, he has various theories to his credit. Legendre’s contribution to the elliptical, physics and mathematical analysis had been a guiding light for various other researchers in the similar field. He served as a professor at the famous science institute in Paris, wherein he also did his research and brought out publications simultaneously. His major areas of work cover elliptic functions, number theory, gravitational attractions, geodesy, calculus and various other branches of mathematics. He has been honored by various titles, membership to commemorate his contributions in the field of mathematics and physics. He developed the least squares method, which has wide ranging application in linear regression, signal processing, statistics, and curve fitting. He gave the concept of Legendre transformation, which is used to go from the Lagrangian to the Hamiltonian formulation of classical mechanics. Legendre transformation is also used in thermodynamics to obtain the enthalpy and the Helmholtz and Gibbs (free) energies from the internal energy.
