It is well-known that in Newtonian mechanics, a system moving with
constant velocity with respect to an inertial one can be proved also
inertial. Have we a similar assertion valid in Einstein's 1905
Relativity (1905R)? According to 1905R, a system moving with constant
velocity with respect to an inertial one can be proved also inertial?
If the answer is positive, I want to know who, when and where proved
it by first time. If those data are not available, I want then any
valid 1905 Relativity deduction of it.

Why would anyone need to prove it when it's simply true by definition?

What definition?

Shubeehttp://www.everythingimportant.org/relativity/special.pdf

The definition of "inertial frame".

You are suggesting that the definition of "inertial system" is "one
moving at constant velocity with respect to...an inertial system? A
little funny, isn't it?

Uh, no.

An inertial frame, by definition, is one moving with constant
velocity. If another frame is moving with constant velocity with
respect to /another/ frame moving with constant velocity, it shouldn't
come as a great shock that it too is an inertial frame.

If I need to expand on this further, you might want to consider not
posting in a physics newsgroup.

In any case, we are considering here Einstein's 1905 Relativity. Only
what Einstein wrote in 1905 is relevant here.

"We" are considering nothing. I will not indulge your obsession.
