Of course, that's because it was a re-derivation. Einstein already had a copy of Lorentz's derivation of the Lorentz transformation, and in a letter to Lorentz in 1905 Einstein said only of his re-derivation of the Lorentz transformation that "its kinematical nature will amuse you". Lorentz's derivation was based on Maxwell's equations - Einstein's contribution was deriving the Lorentz transformation without using Maxwell's equations, and also coming up with E=mc2.

The Michelson–Morley experiment was performed in 1887, long before even Lorentz in 1899.

I'd say the opposite. An very large fraction of all the papers in pure theoretical physics are based on string theory and M-theory derived from it.

I believed in string theory until just before the announcement of the Higgs Boson this month. The LHC failed to find supersymmetry. And string theory rests on supergravity which in turn rests on supersymmetry. Without supersymmetry, string theory is in very serious trouble.
