In 1887 Voigt tried to derive universal formula for Doppler effect in case of a stationary observer and moving source in an elastic incompressible medium . The simple problem was treated in a very complicated way. Solving the set of equations, Voigt found the Doppler formula which was already well-known. Some authors wrongly claim that Voigt proposed the constancy of speed of light in his derivation [2, 3]. Since Voigt’s transformation describes all waves as for example electromagnetic waves, sound waves, and water waves, it is simply not the case .
