Einstein clarified a lot of the subject and added stuff from own, but
how many stuff he simply reused from Lorentz and Poincare? 90%

A tendency in recent historical studies (from a few years ago) is that
main contributors to relativity were (in order of importance): Poincare
and after Lorentz and Einstein (between other authors).

This only can be addressed after defining that one means by plagiarism.

Acording to the Wikipedia:

"Plagiarism is the practice of claiming, or implying, original
authorship, or incorporating material from someone else's written or
creative work in whole or in part, into ones own, without adequate
acknowledgment."

During his entire life Einstein used formulae and results from others
without adequate acknowledgment: call that plagiarism or senility or
bad scientific practice or arrogance or anything you want. It is a fact
material contained in Einstein papers was not from him.

Einstein omited "adequate acknowledgment" with SR and did again with GR
years latter. I think that there is no doubt that Einstein is one of
fathers of GR, probably the most important one. But it is very
difficult to claim that Einstein _is_ the author of SR beyond popular
media.

Often people found concidences between Einstein SR works and previous
works by other authors. Then Einstein in several ocassions was forced
to say in public that he did not know those works, defending the
_originality_ of his works. For instance, Einstein said he never read
POincare previous works

There is a problem, however, there is a historical record saying us
Einstein said not the true often. Solovine letter sttating Einstein and
him both read Poincare 1902 crucial work and _discussed_ before 1905 is
very well-known between historian but unknown for physicists and rest
of general public.

The historian of science Stephen G. Brush stated in Physics Today
[December 2001 Volume 54, Number 12]:

"The French mathematician Henri Poincaré provided inspiration for both
Einstein and Picasso. Einstein read Poincaré's Science and Hypothesis
(French edition 1902, German translation 1904) and discussed it with
his friends in Bern. He might also have read Poincaré's 1898 article
on the measurement of time, in which the synchronization of clocks was
discussed-a topic of professional interest to Einstein as a patent
examiner."

At my best current knowledge, it has not still been historically proven
that Einstein also read Poincare 1898 but sound a strong hypotesis.

How do you call anyone (Einstein) who read works of others, copy in own
works, without citing and after claim that never read?
