christoph gudermann

christoph gudermann -lrb- march 25 , 1798 -- september 25 , 1852 -rrb- was born in vienenburg .
he was the son of a school teacher and became a teacher himself after studying at the university of göttingen , where his advisor was karl friedrich gauss .
he began his teaching career in kleve and then transferred to a school in münster .
he is most known today for being the teacher of karl weierstrass , who took gudermann 's course in elliptic functions , 1839 -- 1840 , the first to be taught in any institute .
weierstrass was greatly influenced by this course , which marked the direction of his own research .
gudermann originated the concept of uniform convergence , in an 1838 paper on elliptic functions , but only observed it informally , neither formalizing it nor using it in his proofs .
instead , weierstrass elaborated and applied uniform convergence .
his researches into spherical geometry and special functions focused on particular cases , so that he did not receive the credit given to those who published more general works .
the gudermannian function , or hyperbolic amplitude , is named after him .
gudermann died in münster .
