Jacques Philippe Marie Binet

In his memoir on the theory of the conjugate axis and of the moment of inertia of bodies he enumerated the principle now known as Binet's theorem.He is also recognized as the first to describe the rule for multiplying matrices in 1812, and Binet's formula expressing Fibonacci numbers in closed form is named in his honour, although the same result was known to Abraham de Moivre a century earlier.In 1823 Binet succeeded Delambre in the chair of astronomy at the Collège de France.[1] He was made a Chevalier in the Légion d'Honneur in 1821, and was elected to the Académie des Sciences in 1843.The Fibonacci sequence is defined by Binet's formula provides a closed-form expression for the
