Special relativity (alternative formulations)
Hendrik Lorentz and Henri Poincaré developed their version of special relativity in a series of papers from about 1900 to 1905. They used Maxwell's equations and the principle of relativity to deduce a theory that is mathematically equivalent to the theory later developed by Einstein.
Stellar aberration (derivation from Lorentz transformation)
In the year 1926 the astrophysicist Robert Emden published the article "Aberration und Relativitätstheorie" in the journal "Naturwissenschaften". In this article he states that the direction of a light ray isn't influenced by the motion of the star or by the motion of Earth. At that time, the opponents of the special theory of relativity reasoned that the theory must be flawed, because it would state that the stellar aberration would depend on the relative velocity of the star — which would be in contradiction to observation — and R. Emden's article explains that the special theory of relativity does not predict this. Today, the special theory of relativity isn't contested anymore but there are still articles that suggest that the aberration would depend on the relative velocity of the star.
