Claude-Louis Navier (10 February 1785 in Dijon ‚Äď 21 August 1836 in Paris) born Claude Louis Marie Henri Navier (French pronunciation: [klod lwi ma Āi …ĎŐÉ Āi naňąvje]), was a French engineer and physicist who specialized in mechanics.
After the death of his father in 1793, Navier's mother left his education in the hands of his uncle Emiland Gauthey, an engineer with the Corps of Bridges and Roads (Corps des Ponts et Chauss√©es). In 1802, Navier enrolled at the √Čcole polytechnique, and in 1804 continued his studies at the √Čcole Nationale des Ponts et Chauss√©es, from which he graduated in 1806. He eventually succeeded his uncle as Inspecteur general at the Corps des Ponts et Chauss√©es.
In 1824, Navier was admitted into the French Academy of Science. In 1830, he took up a professorship at the √Čcole Nationale des Ponts et Chauss√©es, and in the following year succeeded exiled Augustin Louis Cauchy as professor of calculus and mechanics at the √Čcole polytechnique.
Navier formulated the general theory of elasticity in a mathematically usable form (1821), making it available to the field of construction with sufficient accuracy for the first time. In 1819 he succeeded in determining the zero line of mechanical stress, finally correcting Galileo Galilei's incorrect results, and in 1826 he established the elastic modulus as a property of materials independent of the second moment of area. Navier is therefore often considered to be the founder of modern structural analysis.
