I've learnt about significant alternatives to and major extensions to
GR in a totally amateur and piecemeal way and know that I've missed a
lot.

What have been the most significant alternatives to and major
extensions to GR in the past 100 years? What have been the most
important experimental tests of GR in the past 100 years (refs)?

On alternatives and extensions to GR (including discredited ones), I
can think of:
Nordstrom's
Einstein's later attempts at a unified field theory
Kaluza-Klein
Brans-Dicke
Scalar-vector, scalar-tensor, vector-tensor, tensor-tensor,
scalar-vector-tensor theories
Supergravity
Quantum Loop gravity
M-theory
MOND + Brans-Dicke
Berthold-Heim and Droesler's extension
Other?

Rosen's bimetric theory,
RTG (Logunov) with a massive graviton,
my own (gr-qc/0205035).
