Default Who suggested that Light Speed shoud be an impassible limit?

I cant remember who suggested this..

Maxwell along with Einstein, in a sense.

Really, it's a consequence of Einstein's Special Relativity theory.

You mean historically, I presume. Medieval Arabs and Persians, like Avicenna, agreed that light had a finite speed. I think the first methodical thinker to say that was Roger Bacon.

The question is: who decided light speed was a speed limit instead of a plain old fixed number.

actually, i figured it out.
It was Henri Poincare 1904 International Congress of Arts and Science

Henri Poincare who said "Perhaps we must construct a new mechanics [...] in which the speed of light would become an impassable limit." That was in an address to the International Congress of Arts and Science in 1904--before Einstein announced special relativity in 1905.

Hard to say Maxwell didn't suggest this with his theory on electromagnetism.

Lol!

But he did say "perhaps"

Poincare did not agree with special relativity, no matter how close he himself came to it.

I'll try.

Maxwell didn't suggest that the speed of light was a limit, with his theory on electromagnetism.

That wasn't so hard.

My understanding is that Poincaré "got close to the edge, but did not jump" into relativity, too.

Being primarily a mathematician, perhaps he did not feel confident enough to challenge the long-established premises of classical physics.

My literal answer to the OP would be "no one". Science is never about what "should be"-- a seemingly minor but actually quite important nitpick.

As I recall, the idea was booted around before Einstein. Lorentz-Fitzgerald, Maxwell, etc. I have seen claims that Einstein's great insight was that this was the way things really worked.
