The Eclipse that made Einstein Famous

Sir Arthur Eddington's observations of an eclipse in 1919 catapulted Einstein to fame

Produced in partnership with Science at Pioneer Works

On the 29th of May, 1919 the moon eclipsed the sun to allow a thin ray of light from the Hyades star cluster to fall into Sir Arthur Eddington’s telescopes. Through his observations, he proved that light did not travel on straight lines around the sun, but rather on curved ones that deflected light. Eddington's announcement made headlines, catapulting Einstein’s fame in the English-speaking world.
