Carl Gustav Jacob Jacobi
Carl Gustav Jacob Jacobi( 10 December 1804 – 18 February 1851) was a German mathematician who made fundamental contributions to elliptic functions, dynamics, differential equations, determinants, and number theory.
His name is occasionally written as Carolus Gustavus Iacobus Iacobi in his Latin books, and his first name is sometimes given as Karl.
Jacobi was the first Jewish mathematician to be appointed professor at a German university.
Friedrich Julius Richelot
Friedrich Julius Richelot (6 November 1808 – 31 March 1875) was a German mathematician, born in Königsberg.
He was a student of Carl Gustav Jacob Jacobi.
He was promoted in 1831 at the Philosophical Faculty of the University of Königsberg with a dissertation on the division of the circle into 257 equal parts (see references) and was a professor there.
Richelot authored numerous publications in German, French and Latin, among them — with his 1832 dissertation — the first known guide to the Euclidean construction of the regular 257-gon with compass and straightedge.
In 1825 he joined the Corps Masovia.
He died in Königsberg in 1875.
Theodor Schönemann
Theodor Schönemann, also written Schoenemann( 4 April 181216 January 1868), was a German mathematician who obtained several important results in number theory concerning the theory of congruences, which can be found in several publications in Crelle's journal, volumes 17 to 40.
Notably he obtained Hensel's lemma before Hensel, Scholz's reciprocity law before Scholz, and formulated Eisenstein's criterion before Eisenstein.
He also studied, under the form of integer polynomials modulo both a prime number and an irreducible polynomial( remaining irreducible modulo that prime number), what can nowadays be recognized as finite fields( more general than those of prime order).
He was educated in Königsberg and Berlin, where among his teachers were Jakob Steiner and Carl Gustav Jacob Jacobi.
He obtained his doctorate in 1842, after which he became Gymnasialoberlehrer( professor at a gymnasium) in Brandenburg an der Havel.
Apart from the mentioned mathematical papers, he also published, mainly after 1850, in mechanics and physical technique.

At the University of Königsberg he studied mathematics under Carl Gustav Jacob Jacobi and Friedrich Julius Richelot, and oriental philology under Peter von Bohlen.
