The use of multiple compensators in N = 1 supergravity is considered. It is shown that supersymmetry may be broken by the solution to the Euler-Lagrange equations of a compensator, even though the action is supersymmetric. The spontaneous violation of supersymmetry present in the non-minimal supergravity of Breitenlohner, when there is a cosmological term, is shown to be due to the linear compensator of this theory. A reducible supergravity, which extends old minimal supergravity by including additional compensators, is also shown to break supersymmetry in this way. It is shown that the compensator method of supersymmetry breaking can be compatible with symmetry breaking by scalar matter, by verifying that the super Higgs-Kibble effect is operative in a model. Other aspects of this model are discussed, and the complete component Lagrangian is obtained. The flexibility of the compensator coupling is illustrated in an example in which the gaugino is made massive without the use of non-minimal coupling of scalar fields. The most general coupling of multiple compensators is discussed, and possible applications of this mechanism of supersymmetry breaking are indicated.
