The eclipse itself was on 29 May 1919; this pin is the announcement, which is what made Einstein famous.
Arthur Eddington presents the results of the May 1919 eclipse expeditions to Principe and Sobral at a joint session of the Royal Society and the Royal Astronomical Society at Burlington House. The measured deflection of starlight matches Einstein's prediction, and the meeting accepts it.
