The 1919 solar eclipse observations made Albert Einstein a global celebrity because they provided the first experimental evidence for his general theory of relativity, which had been published in 1915 and remained controversial among scientists.12

Einstein’s theory predicted that gravity would cause light from distant stars to bend as it passed near the Sun, specifically by an angle of 1.75 arc seconds. Because the Sun’s brightness normally obscures nearby stars, this effect could only be tested during a total solar eclipse.13

In May 1919, expeditions led by Arthur Eddington and Frank Dyson photographed stars near the Sun during an eclipse. When they announced in November that their findings supported Einstein’s prediction, the news was met with massive media coverage. Headlines like "Revolution in Science" captured the public imagination, transforming Einstein from a physicist into an international icon of intellectual genius.123
