Einstein had most likely also quoted Heinrich Hertz, but without

 quoting?? the Einstine was so stupid not remembering his own quotes. Not remembering he had any quotes. He was just delivering patents to other people to undrestand. You take from the left and give it to the right.

I have actually obtained copies of the books of Heinrich Hertz and spent some time on searching for similarities to Einstein's text.
As German is my primary language, I had no difficulty in reading them.
Hertz was also a very good writer and so it was not hat difficult to read his papers.
I have searched his works (few, actually, as he died relatively young) and found a lot of things, which looked like Einstein's text.
As Einstein actually had mentioned the name 'Hertz', I was allowed to assume, that Einstein had read the books of Heinrich Hertz, too.
But Hertz was a convinced 'aetherist', while Einstein wasn't.
Hertz also used very similar equations, but with total derivatives, where Einstein used partial derivatives.
Hertz used also almost the same variable names, especially for the components of the electric and magnetic field strength vectors.
So: I found similarities, but also differences.
These differences are now, what is actually critical, because 'wrong quotes' are actually worse than 'no quotes'.
