Florimond de Beaune

Florimond de Beaune (7 October 1601, Blois – 18 August 1652, Blois) was a French jurist R. Taton calls him "a typical example of the erudite amateurs" active in 17th-century science.

His Tractatus de limitibus aequationum was reprinted in England in 1807; in it, he finds upper and lower bounds for the solutions to quadratic equations and cubic equations, as simple functions of the coefficients of these equations. Another of his writings was Notae breves, the introduction to a 1649 edition of Descartes' La Géométrie.
