Br. Rich,
We Catholics often identify Luther with Protestantism, so I’m glad you pointed out other Reformers from different traditions as well. Let’s also not forget the Waldensians and later the Anabaptists.
In general,
Actually, if I remember my readings of Luther correctly, he did not even necessarily deny a transubstantiation-like Real Presence, but found the idea so philosophically complicated that he could not see how an ordinary peasant in the pews could be expected to be able to believe it. Of course, just as in all other brands of Protestantism, Lutheranism is no longer the denomination of its founder.
If you are looking for the original movement to deny the Real Presence that was able to gain a substantial following, you’ve got to go all the way back to Berengarius, who lived in (I believe) the 10th century. I also think he later recanted his heresy. (You can see from my level of certainty that I’m no Church historian).
