Note: Einstein's first work on general relativity (e.g. the equivalence
principle, gravitational time dilation. deflection of light, etc.) was in a
paper published in 1907 called "On the Relativity Principle and the
Conclusions Drawn from it," A. Einstein, Jahrbuch der Radioaktivitat und
Elektronik 4 (1907): 411-462. And contrary to Roberts claim, GR *does( have
this property. It is a very simple thing to derive. E.g.
