The aim of this work is to construct families of weighing matrices via automorphisms and cohomology. We study some well known families such as Payley's conference and Hadamard matrices and Projective Space weighing matrices, and put them in the context of a general theory. As a consequence, we get the new family of Grassmannian weighing matrices. Our theory generalizes the theory of Cocyclic matrices.
