Originally, local time was FOUND by Voigt in 1887. Here is the link:

Lorentz "borrowed" Voigt's local time, without crediting him.

 Lirentz' local time is not the same as Voigt's.
 Local time is the isometric coordinate time of an isometric
coordinate system. An important aspect to understand about
it is that it is not local. It is valid for the region where
the coordinate system is valid. At the time Voigt, Larmor and
Lorentz presented their transformations it was assumed that
the entire Universe could be covered with one such system.
 

What is more interesting than Hendrik Lorentz, that is Einstein's 'On the electrodynamics of moving bodies'.
I have found similarities to Heinrich Herth and his book 'Über die elektrische Kraft'.
But Voigt's text was seemingly a source, too.
Have not checked that yet, but the equations look somehow similar.
Also form, style, variable names and overall structure look quite familiar for me.
