Abstract: If $N$ is a finitely generated nilpotent group which is not abelian-by-finite, $k$ a field, and $D$ a finite dimensional separable division algebra over $k$, then there exists a simple module $M$ for the group ring $k[G]$ with endomorphism ring $D$. An example is given to show that this cannot be extended to polycyclic groups.
