In the first one among others reminiscences from students and members of Schurs family are presented, followed by a biographical sketch through letters and other documents and an extensive review of his lesser known contributions to analysis. The second part contains 13 contributions to representation theory. Schur proper field of research... Many of these articles are inspired by Schurs work showing how fertile his ideas are even [for] today." ---Monatshefte fur Mathematik
