Einstein & Light Deviation: Compute w/o Schwarzschild Metric

[e2m2a]

How did Einstein compute the amount of light deviation due to the Earth's gravitational field when the Schwarzschild metric was not known yet?

He didn't get it right at the first try, in fact in his first calculations in 1908 he was off by a factor of 2. The correct result was obtained 1915 using the weak field approximation where all terms smaller than the order of 1/c³ were neglected, see http://home.fnal.gov/~syphers/Education/Notes/lightbend.pdf
