No. Lorentz contraction is called Lorentz contraction (or sometimes Lorentz-Fitzgerald contraction), and the Lorentz Transformations are called the Lorentz Transformations, appropriately enough, because Lorentz also figured out time dilation.
Poincaré is amply credited with maintaining the principal of relativity. Galileo doesn't get enough credit for starting the relativity schtick, or for his five laws of motion that Newton condensed into three laws.
One can never tell with historians of science, though. They tend to be a bit dingy, though not quite as dingy as philosophers of science.
