If R is a simple ring with 1 which contains a maximal annihilator right ideal then R is the endomorphism ring of a unital torsion-free module over an integral domain.We first prove the following:Let R be a ring with 1. If a ε R such that (a)r = {r ε R|ar = 0} is a maximal annihilator right ideal then HomR(aR, aR) is an integral domain.
