Abstract Because of Lorentz and gauge invariance the zero energy limit of Compton scattering, the Thomson limit, is an exact property of QED. Because of supersymmetry this is proved also to be an exact property of the unbroken, supersymmetric extension of QED (SQED). If supersymmetry, on the other hand, is explicitly broken, the Thomson limit from QED is not recovered from the one-loop calculation in SQED. After renormalization we prove that there will be a nonvanishing modification of the classical electron radius {ital r}{sub {ital e}} because of the breaking of supersymmetry. {copyright} {ital 1996 The American Physical Society.}
