This is the opening page of a journal article by Xavier Roqué, communicated by K. von Meyenn, on the history of Christian Møller's electron-electron scattering work in the early 1930s. The contents cover Møller's method, derivation of the Møller formula, its relation to quantum electrodynamics, and experimental tests from Champion's experiments to the postwar conclusive test. A footnote notes that it complements Helge Kragh's earlier study.

Introduction*
The first attempts to build a quantum and relativistic theory of electro-
magnetic interactions date back to the mid-twenties, though not until the full
* In an article recently published in this Archive, HELGE KRAGH has analyzed the
background and development of CHRISTIAN MOLLER's work on electron scattering in the
early thirties. The fact that most of my paper was written while I was unaware of
KRAGH's work, accounts for the similitudes. This article complements that of KRAGH in
that Mt~LLER's actual deduction of his scattering formula, as well as its experimental test,
are analyzed in greater detail.
