Henri Desargues

Henri Desargues was a French mathematician and engineer in the 17th century who made significant contributions to projective geometry. He introduced the concept of perspective and the idea that certain geometric properties remain consistent when objects are viewed from different angles, forming the foundation of modern geometric concepts like points and lines at infinity. His work laid the groundwork for understanding how shapes and figures transform visually, influencing both mathematics and art. Desargues is best known for the “Desargues’ Theorem,” a fundamental principle describing how two triangles relate when projected from different viewpoints.
