Girard Desargues was a French mathematician and engineer who lived during the 17th century (1591–1661). He is best known for his work in projective geometry and is often regarded as one of the founders of this field. Desargues' most significant contribution is the formulation of what is now known as Desargues' theorem, which describes the relationship between two triangles located in perspective from a point.
