Claude Guichard (1862-1926) was a French mathematician, a correspondent of the Institut, and a professor at the University of Clermont. He is known for his contributions to differential geometry. This work is a paper on the theory of the deformation of quadrics, a geometry topic that deals with second-degree surfaces.
