Many contributed, as in any science, and Einstein put things together to move forward. Of course he was aware of the works of his peers (although there is no proof to which degree). But he has not copied them and Lorentz and Poincare works have never formulated the theory of special relativity as such.

Einstein derived Lorentz transformation starting from special relativity. No one did that before. Lorentz transformations are called Lorentz transformations and not Einstein transformations (and similarly, there is something known as the Poincare group and not the Einstein group). This is where recognition is given to Lorentz to what he contributed for. Moreover, Einstein cited Poincare's work in one of his paper on relativity. Isn't this giving credits?

Finally, if you go back to the literature, you will notice that there are fundamental differences between Einstein work and Lorentz a d Poincare works. He is the one who got rid of the aether concept in the 1900s and the concept of absolute space. It is unfair from taking that out from Einstein (which is at the end why he his theory of special relativity is known).

I do not know what you need, but your claims are just not founded. And when I wrote about jealousy, I was thinking to people attacking Einstein today...
