Ecole girard desargues biography

Description

Richelieu visits Desargues visit at the fortifications of La Rochelle. Girard Desargues (February 21, - September ) was a French mathematician and engineer. He worked as a tutor and may have served as an engineer and technical consultant in the entourage of Richelieu. As an architect, Desargues planned several private and public buildings in Paris and Lyon. As an engineer, he designed a system for raising water that he installed near Paris. It was based on the use of the at the time unrecognized principle of the epicycloidal wheel. His research on perspective and geometrical projections can be seen as a culmination of centuries of scientific inquiry across the classical epoch in optics that stretched from al-Hasan Ibn al-Haytham (Alhazen) to Johannes Kepler, and going beyond a mere synthesis of these traditions with Renaissance perspective theories and practices. He is considered one of the founders of projective geometry, the stu

Biography

Girard Desargues's family (on both his mother's and his father's side) had been very rich for several generations and had supplied lawyers and judges to the Parlement in Paris as well as to that in Lyon (then the second most important city in France). Girard's father, also having the name Girard Desargues, married Jeanne Croppet in Condrieu a small town in the Rhône department in eastern France. They moved to Lyon but certainly retained the property in Condrieu since Girard (Junior) spent time there towards the end of his life. In Lyon Girard (Senior) worked as an investigator for the bailiff, then as a tax collector and royal notary, which was his occupations when his son Girard was born.
