dedicated to professor w. t. tutte on the occasion of his eightieth birthday We characterize the symmetric (0, 1)-matrices that can be signed symmetrically so that every principal submatrix has determinant 0, \1. This characterization generalizes Tutte's famous characterization of totally unimodula
