Maps of Solar Eclipses from 1915 to 1919

Probably the most important scientific discovery from any solar eclipse was the validation of Einstein’s theory of relativity during the eclipse of 1919 May 29. Arthur Eddington conducted an expedition to the island of Principe off the west coast of Africa, and by measuring the displacement of stars near the eclipse sun, announced that he had verified Einstein’s theory. This announcement overnight propelled Einstein to international fame. Note the magnificent coronal prominence which occurred during this eclipse.
