Understanding Einstein's simple derivation of the Lorentz Transformation

I disagree. Lorentz obtained the transform equation via an ansatz, without
justification or explanation. He did not even display them in the form we use
today until after 1905. Einstein derived them from his two postulates, and
displayed them in the form used today. I believe Einstein was instrumental in
christening them "Lorentz transformations". The earlier paper by Voigt that
displayed an equivalent transform was not (re-)discovered until the name
"Lorentz transform" was well established.
