My most important contribution to the history of relativity was the
presentation of the first analysis of Einstein's "Zurich Notebook."
It turned out to contain Einstein's private calculations for the
crucial period of the making of his greatest discovery, the general
theory of relativity. The notebook enabled a reconstruction of
Einstein's path from the earliest insight of an essential connection
between gravitation and the curvature of spacetime through to the
juggling of the complicated expressions that eventually become the
Einstein equations. The notebook also explained in detail the
outstanding puzzle of why Einstein rejected these famous equations in
1913, only to return to them ruefully two years later. My work on
this notebook has continued in collaboration with a group of
historians of science under the auspices of the Max Planck Institute
for History of Science in Berlin and has lead to our joint
publication of the definitive multivolume work on the notebook.

Two fundamental errors led Einstein to reject generally covariant
gravitational field equations for over two years as he was developing
his general theory of relativity. The first is now well known. It was
the presumption that weak, static gravitational fields must be
spatially flat and a corresponding assumption about his weak field
equations. I conjecture that a second hitherto unrecognized error
also defeated Einstein's efforts: he unwittingly reified his
spacetime coordinate systems. The same error, months later, allowed
the hole argument to convince Einstein that all generally covariant
gravitational field equations would be physically uninteresting.

Other related work includes a study of the Nordstroem theory of gravitation, which Einstein identified as the serious competitor to his newly emerging general relativity. Einstein was able to show that even this most conservative of theories led to the same outcome, the association of gravitation with a curvature of spacetime.

In the late 1890s, Seeliger showed that the simplest and most natural Newtonian cosmology was paradoxical. This paradox, which even tripped up Newton, was used by Einstein to motivate introduction of his cosmological constant. I have surveyed and catalogued the many responses in the literature to this paradox.  "The Cosmological Woes of Newtonian Gravitation
