In the period 1907-1915 Einstein was only able to plagiarize Newton's emission theory of light insofar as the speed of light in a gravitational field was concerned:

Albert Einstein: "If we call the velocity of light at the origin of co-ordinates c0, then the velocity of light c at a place with the gravitation potential phi will be given by the relation c=c0(1+phi/c^2)."

The formula c=c0(1+phi/c^2) implies that, in a gravitational field, the speed of photons varies exactly as the speed of cannonballs does. This interpretation, confirmed by the Pound-Rebka experiment, is so obviously correct that some Einsteinians teach it even nowadays:

"So, it is absolutely true that the speed of light is not constant in a gravitational field [which, by the equivalence principle, applies as well to accelerating (non-inertial) frames of reference]. If this were not so, there would be no bending of light by the gravitational field of stars....Indeed, this is exactly how Einstein did the calculation in: 'On the Influence of Gravitation on the Propagation of Light,' Annalen der Physik, 35, 1911... (...) ...Einstein's derivation of the (variable) speed of light in a gravitational potential, eqn (3). The result is, c'=c0(1+V/c^2), where V is the gravitational potential relative to the point where the speed of light c0 is measured."
