Dismissing renewed attempts to deny Einstein the discovery of special relativity

Abstract

On the occasion of the centenary of special relativity, several publications have argued that Poincaré, and not Einstein, was the discoverer of special relativity. Attacks have simultaneously been directed at Einstein, whose 1905 article on the electrodynamics of moving bodies was alleged to be a forgery. These attacks praise Lorentz and Poincaré for their results and neglect Poincaré’s failure to make the necessary conceptual leap and understand the fundamental consequences of the principle of relativity. I identify what was missing in Lorentz’s and Poincaré’s views and contrast them with Einstein’s insights.
