Einstein became world-famous on 7 November 1919, following press publicationof a meeting held in London on 6 November 1919 where the results were announcedof two British expeditions led by Eddington, Dyson and Davidson to measure howmuch background starlight is bent as it passes the Sun. Three data sets wereobtained: two showed the measured deflection matched the theoretical predictionof Einstein's 1915 Theory of General Relativity, and became the officialresult; the third was discarded as defective. At the time, the experimentalresult was accepted by the expert astronomical community. However, in 1980 astudy by philosophers of science Earman and Glymour claimed that the dataselection in the 1919 analysis was flawed and that the discarded data set wasfully valid and was not consistent with the Einstein prediction, and that,therefore, the overall result did not verify General Relativity. This claim,and the resulting accusation of Eddington's bias, was repeated withexaggeration in later literature, and has become ubiquitous. The 1919 and 1980analyses of the same data provide two discordant conclusions. We reanalyse the1919 data, and identify the error that undermines the conclusions of Earman andGlymour.

The 1919 eclipse results which verified General Relativity and their later detractors: a story re-told
