SUMMARY
In 1919, Andrew Crommelin and Charles Davidson of the Royal Greenwich Observatory captured the crucial photographs during a solar eclipse in Brazil. These images, taken with a backup telescope, provided the sharpest measurements and definitively proved Albert Einstein's theory of general relativity. Despite their pivotal role, Arthur Eddington, who led the expedition to Príncipe, received the majority of the credit and public recognition for the experiment.
TAKEAWAYS
Crommelin and Davidson's 1919 eclipse photos proved Einstein's theory of relativity.
Their images, taken with a spare telescope in Brazil, were sharper than Eddington's.
Arthur Eddington received historical credit for the scientific breakthrough.
The situation highlights how credit for a photograph can be misattributed.
