message: Looking through that paper without really studying it (it's a big nut to crack!), I find the following:
1. The footnote in his 1888 paper seems to accept Michelson's conclusion that the earth entrains the aether; it's unclear to me if he revised his theory or if he had simply not noticed that his 1887 theory does not correspond with Michelson's analysis. 
2. Apart of the footnote on p.390, Voigt makes the following remark on p.550, after showing that the polarization in quartz should rotate notably in case of a translational speed relative to the ether:
"Marcart's observations may be regarded as a confirmation of Michelson's observations from which followed that the aether is approximately at rest relative to the earth's surface."  (loosely translated)
Perhaps someone else here can clarify why Voigt apparently accepted Michelson's analysis?!

Well, Kelvin-Voigt material is named after him.  Can we say he was named for it??  I can't see a reference on the page!

message: The side bar with his basic data has flags of Germany for his birth and death places.  But the flags are the ones for modern Germany.  Shouldn't the flags shown be the green and white Kingdom of Saxony for birth, and the Red White and Black Imperial flag for death?

message: The article makes a wrong statement at the end about Lorentz and his transformation:
"If Lorentz had adopted this transformation, it would have been a matter of experiment to decide between them and the modern Lorentz transformation."
The very same wrong statement could be made about Einstein. According to Lorentz 1904, only the Lorentz contraction can be compatible with the PoR, and thus it was *not* up to experiment to decide which one he could have chosen. The different transformations relate to each other by a factor l, and Lorentz concluded that necessarily l=1:
"so that we must put [...] l = const.
The value of the constant must be unity, because we know already that, for w=0, l=1.
We are therefore led to suppose that the influence of a translation on the dimensions (of the separate electrons and of a ponderable body as a whole) is confined to those that have the direction of the motion, these becoming k times smaller than they are in the state of rest. " (emphasis mine)

I will therefore correct the wrong statement.
