Pierre Ossian Bonnet

Pierre Ossian Bonnet was a French mathematician and astronomer known for his contributions to geometry and the study of surfaces. He is best recognized for his work on the theory of curves and surfaces, particularly in relation to what are now known as Bonnet's equations. Bonnet's insights into differential geometry laid foundational concepts that later influenced the development of modern mathematics and physics. His work also included research in the field of astronomy, where he contributed to understanding celestial mechanics. Overall, Bonnet's legacy is significant in both mathematics and the natural sciences.
