However, Einstein's theory of General Relativity predicted that gravity would bend the path of light, and a solar eclipse provided a perfect opportunity to test this prediction. During the 1919 eclipse, astronomers Arthur Eddington and Frank Dyson led expeditions to observe the eclipse and measure the bending of starlight around the Sun. This experiment confirmed Einstein's theory and catapulted him to fame.
So, while Einstein didn't personally photograph the eclipse, his theory was the driving force behind the scientific expedition that made the observations.
