Rectification of Erroneous Chronological Dating of Three Anecdotal Events Occurring in the Early History of Radiology in Berlin

The authors define corrected dates of three remarkable events of early history of radiology in Berlin, which have been wrongly reported in the literature. Compiled evidence from contemporary newspaper publications demonstrates that Röntgen delivered his lecture to kaiser William II on 12 January 1896. Paul Spies gave a lecture on Röntgen rays to the Reichstag on 13 February 1896. The first publicly taken X-ray in Berlin was obtained on 20 January 1896.
