Germany actually did invent this. The brothers Wright only stuck an engine to it. The first glider that actually deserved its name was inveted by Otto Lilienthal. He died in it. Without his work, the Wright brothers would not have been able to build their plane.

Technically, the Wrights’ main contribution was the 3-axis steering mechanism, which is what made powered flight practical.

I agree. Lilienthal showed a proof of concept. The Wrights made it practical. As soon as aerodynamics was understood a bit better, there was enough lift, to move the whole elevator assembli to the back of the plane, but apart from that, the whole thing still is the most practical approach.
