A passage from Einstein's paper, written in German, arguing that starlight passing very near the Sun should be deflefted about 1.7 arc seconds from its original trajectory.

   It's good that Einstein had to wait a few years, because he was predicting the wrong amount of deflection in 1913. He had applied the equivalence principle to Newtonian gravity and obtained a prediction of 0.85 arc-second.

   In his 1915 paper “Explanation of the Perihelion Motion of Mercury from the General Theory of Relativity,” he used the full apparatus of general relativity to predict the correct 1.7 arc-second deflection for a light ray just grazing the sun.
