Issai Schur was born into a Jewish family, the son of the businessman Moses Schur and his wife Golde Schur (née Landau).

He went to Latvia at the age of 13 and there he attended the Gymnasium in Libau, now called Liepaja. In Schur entered the University of Berlin to read mathematics and physics. Frobenius was one of his teachers and he was to greatly influence Schur and later to direct his doctoral studies. Frobenius and Burnside had been the two main founders of the theory of representations of groups as groups of matrices.

This theory proved a very powerful tool in the study of groups and Schur was to learn the foundations of this subject from Frobenius. Schur then made major steps forward, both in work of his own and work done in collaboration with Frobenius.

Issai Schur was born into a Jewish family, the son of the businessman Moses Schur and his .

In Schur obtained his doctorate with a thesis which examined rational representations of the general linear group over the complex field. Interest in the results of Schur's thesis continues today; for example J A Green published an account of these results in a modern setting in In Schur became a lecturer at Berlin University and then, from until , he held a professorship in mathematics at the University of Bonn.

He returned to Berlin in and there he built his famous school and spent most of the rest of his life there. He was promoted to full professor in Berlin in , three years after he returned there, and he held this chair until he was dismissed by the Nazis in Schur is mainly known for his fundamental work on the representation theory of groups but he also worked in number theory , analysis and other topics described below.

Between and he worked on projective representations of groups and group characters.
