"Hartree's chief contribution to science was his development of powerful methods of numerical mathematical analysis, which made it possible for him to apply successfully the so-called self-consistent field method to the calculation of atomic wave functions of polyelectronic atoms, that is, those which in the neutral condition have more than one electron surrounding the nucleus. These calculations involved the numerical solution of the partial differential equations of quantum mechanics for many-body systems subject to the usual boundary conditions" (D. S. B. 6: 147). Chapter 12 is "Organization of Calculations for an Automatic Machine" (pp. 255-273).

"Hartree and his collaborators evaluated wave functions for more than twenty-five different atomic species in various states of ionization. Through his stimulus and encouragement many more atoms were investigated by physicists throughout the world. Hartree's equations as generalized by V. Fock proved to be extremely valuable in theoretical calculations in sold state physics." DSB, VI, p. 147.
