Sirs:

It seems theory of relativity follows inevitably from data developed by M/M. Specifically, once the speed of light is determined to be a constant in all directions from a moving earth, what else could account for the data?

Put another way. Could Einstein or anyone else have developed the theory in absence of this data.

The MM data only showed that the aether theory was wrong. Einstein was more directly influenced by James C Maxwell's equations.

Could someone else have come up with a finite speed of light? Most definitely.

Anyway, wasn't the speed of light measured to finite before Einstein? There was this method shining light on a turning "wheel" (don't know the english word, I mean a wheel like a turbine, so the light pass only every x seconds)

To: Tormod: You wrote: "...Einstein was more directly influenced by James C Maxwell's equations."

"... the theory of electromagnetism was developed into Maxwell's equations [that] describe waves with a speed of 1/sqrt(epsilono*muo) ... This is an absolute velocity [that] was very close to the measured speed of light..."

I can easily understand M/M. However, I do not understand Maxwell. Did he have experimental data that led to this speed equation? And did he understand it to be absolute in all directions from a moving source? Absolute in all directions seems the logical conclusion from M/M, but I am not a mathematician and do not understand this in Maxwell.
