Michel Brisard: A Renowned Engineer and Mathematician

Michel Brisard was a pivotal figure in both engineering and mathematics. His most notable contributions lie in geometry, particularly in descriptive geometry and the problem of decomposing polyhedra. He also excelled in kinematics, especially in the study of articulated mechanisms.

Academic Career

Brisard imparted his knowledge of geometry at the École Centrale des Arts et Manufactures in Paris. In 1908, he ascended to the professorship of applied geometry at the Conservatoire National des Arts et Métiers, also in Paris. His exceptional work in geometry earned him the prestigious Poncelet Prize from the French Academy of Sciences in 1932.

Esperanto Connections

Brisard's name appears in the Esperanto encyclopedia. His interest in this international language is evident in his article on Hilbert's third problem, published in 1896. Interestingly, Brisard's publication predates Hilbert's formalization of the problem.

Seminal Contributions

In 1897, Brisard released a seminal work on flexible polyhedra. It featured a groundbreaking classification of flexible octahedra, a discovery later highlighted in a lecture by Henri Lebesgue in 1938. Brisard's exploration of kinematics led to the discovery of six-link mechanisms. Furthermore, he provided the first geometric proof of Morley's theorem on trisectors in 1922.
