The purpose of this paper is to prove the following result. Let be a complex Hilbert space, let () be the algebra of all bounded linear operators on and let () () be a standard operator algebra, which is closed under the adjoint operation. Let : () () be a linear mapping satisfying the relation 2(*) = ()* + *() for all (). In this case is of the form () = λ for all (), where λ is some fixed complex number.
