The theory of the inhomogeneous electron gas had its origin in the
Thomas Fermi statistical theory, which is discussed in the first
chapter of this book. This already leads to significant physical
results for the binding energies of atomic ions, though because it
leaves out shell structure the results of such a theory cannot
reflect the richness of the Periodic Table. Therefore, for a long
time, the earlier method proposed by Hartree, in which each
electron is assigned its own personal wave function and energy,
dominated atomic theory. The extension of the Hartree theory by
Fock, to include exchange, had its parallel in the density
description when Dirac showed how to incorporate exchange in the
Thomas-Fermi theory. Considerably later, in 1951, Slater, in an
important paper, showed how a result similar to but not identical
with that of Dirac followed as a simplification of the Hartree-Fock
method. It was Gombas and other workers who recognized that one
could also incorporate electron correlation consistently into the
Thomas-Fermi-Dirac theory by using uniform electron gas relations
locally, and progress had been made along all these avenues by the
1950s."
