Zusammenfassung:	The algebraic classification of second-order symmetric tensors based on Segre type is used to give a systematic description of energy-momentum tensors in General Relativity. The uniqueness of the physical interpretation of a given energy-momentum tensor is discussed algebraically and a brief description of their ''inheritance of symmetry'' properties is also given.
