Gaspar Monge: Founder of Descriptive Geometry

Gaspar Monge (10.5.1746-28.7.1818) was a French mathematician, geometer, and public figure. He was a member of the Paris Academy of Sciences and the creator of descriptive geometry. Monge was born in Bon-Côte-d'Or and graduated from the School of Military Engineers in Mézières. He became a professor of mathematics in 1768 and later also a professor of physics at the same school. From 1780, he taught hydraulics at the Louvre School in Paris.

Contributions to Mathematics and Science

Monge made significant contributions to various fields, including mathematical analysis, chemistry, meteorology, and practical mechanics. During the French Revolution, he worked on the commission for establishing a new system of weights and measures. He also served as the Minister of the Navy and organizer of national defense.

Collaboration with Napoleon and the Egyptian Institute

During the Directory, Monge developed a close relationship with Napoleon Bonaparte. He participated in Napoleon's campaign in Egypt and played a key role in the establishment of the Egyptian Institute in Cairo in 1798. As a result of his contributions, Monge was granted the title of Count.

Founding the École Polytechnique

Monge was one of the organizers of the École Polytechnique in Paris and served as its director for many years. In the 1770s, he created modern methods of projection drawing, which formed the basis of descriptive geometry. His most important work on the subject, "Descriptive Geometry," was published in 1799.

Advancements in Differential Geometry

Monge also made important discoveries in differential geometry. His earliest works on surface equations were published in 1770 and 1773. In 1795 and 1801, he published works on finite and differential equations of various surfaces. In 1804, his book "Application of Analysis in Geometry" was published, in which he examined cylindrical and conical surfaces formed by the motion of a horizontal line through a fixed vertical line, surfaces of "canals" where the lines of steepest slope form a constant angle with the horizontal plane, surfaces of translation, etc. As an application, Monge presented his theory of integrating first-order partial differential equations and his solution to the problem of string vibrations. He derived differential and finite equations for each type of surface.

Gaspar Monge's groundbreaking work in descriptive geometry and contributions to various mathematical fields have earned him worldwide recognition. His legacy continues to influence the study of mathematics and science to this day.
