Nonsense. *Voigt was the first to speculate on the constancy in the
speed of light. *As a modification to the Galilean transform, the
Voigt transform does not invoke time dilation. *However, it has other
problems. *The Lorentz transform was first put together by Larmor, and
in doing so, Larmor had already noticed such a situation in time
dilation.

He thought that if *the length *of a moving object contracted, its
time *had to slow down or the speed of light would not be constant.
However, Lorentz achieved the opposite effect with his thought
process.

This confusion results when a plagiarist plagiarizes on a master's
work without understanding the very fundamental principle involved.

KoWu,
Maxwell was the first to include the speed of light as a constant in
his equations.
Voigt was the first to formulate the 'Lorentz' transforms. Larmor was
the second. Lorentz was the third. Lorentz corresponded with Voigt.
Lorentz may have been the first to come up with time dilation. I am
not sure.
