*“It is concluded that the sun's gravitational field gives the deflection predicted by Einstein's general theory of relativity.”*

I've bumped into a famous piece of phsyics history, a semi-popular report on the verification of the Einstein theory of general relativity. The article is “Eclipse Photographs Verify Einstein's Prediction” adn is found in *Popular Astronomy *(published in Northfield Minnesota, volume 28, 1920, the issue for January, #1, 1920, with the notice appearing on pp 69-70.) At about the same time there appears the famous and deciding report by F. W. Dyson, A. S. Eddington, and C. Davidson, "A Determination of the Deflection of Light by the Sun's Gravitational Field, from Observations Made at the Total Eclipse of May 29, 1919" which appeared in the *Philosophical Transactions of the Royal Society of London. Series A, Containing Papers of a Mathematical or Physical Character *for 1920* (*pp 291-332). This is the integral report on which *Popular Astronomy* reports on for a more general astronomy readership.

This report repeats the famous finding: “It is concluded that the sun's gravitational field gives the deflection predicted by Einstein's general theory of relativity.”
