Could you explain how it did inspire Einstein, and if Einstein gave him any credit for any of his ideas?
It’s perhaps not so well known that Gauss was inspired by Kant to theorise non-Euclidean Geometry. Riemann was a student of Gauss and was inspired to come up with the general notion of Riemannian manifolds. This was definitely enough for Clifford to hypothesise that forces are, essentially, waves in space. Einstein as well as Nordstrom took up this technology to theorise gravity in a geometrical form. This notion has spread to all the other forces, so we generally think of forces as geometrical in some way or another.
It’s possible to speculate, in the way that the modern notion of atoms has its antecedent in Democritean atoms, that the modern notion of waves is due to Thales thinking of the world as water.
