Page "Aether drag hypothesis" Paragraph 16

However, the accumulation of hypotheses to rescue the stationary aether concept was considered to be very artificial.

So it was Albert Einstein, who recognized that it is only required to assume the principle of relativity and the constancy of the speed of light in all inertial frames of references, in order to develop the theory of special relativity and to derive the complete Lorentz transformation.

All this was done without using the stationary aether concept.
