Claim: Christoph Gudermann was a Mathematician and a teacher famous for creating the Gudermannian function and the idea of Uniform convergence.
Evidence: Christoph Gudermann (25 March 1798 – 25 September 1852) was a German mathematician noted for introducing the Gudermannian function and the concept of uniform convergence, and for being the teacher of Karl Weierstrass, who was greatly influenced by Gudermann's course on elliptic functions in 1839–1840, the first such course to be taught in any institute.
