Carl Wilhelm Borchardt

Karl Wilhelm Borchardt ( born February 22, 1817 in Berlin, † June 27, 1880 in Ruedersdorf in Berlin) was a German mathematician.

Life

He came from a Jewish family from Berlin. Borchardt studied since 1836 in Berlin with Peter Gustav Lejeune Dirichlet mathematics and moved in 1839 to Königsberg to study with Friedrich Wilhelm Bessel, Franz Ernst Neumann and especially Carl Gustav Jacob Jacobi. In his doctoral thesis he treated non-linear differential equations.

With Jacobi he went 1843/1844 to Italy and was subsequently employed for several years with independent mathematical studies in Berlin. In the winter of 1846/1847 he spent in Paris and his habilitation in 1848 at the University of Berlin. In 1856 he became a full member of the Academy of Sciences in Berlin, and then took over the continuation of Crelle Journal of Pure and Applied Mathematics.

Borchardt was buried in the cemetery III of Jerusalem and the New Church in Berlin- Kreuzberg. The grave has been preserved.

Borchardt began with the publication of the works of his teacher Jacobi, whose first volume was published after his death in 1881. The publication was continued by Karl Weierstrass.
