Couffignal started his career as a teacher of mathematics and mechanics at the École des Élèves Ingenieurs Mecaniciens, which is part of the École Navale de Brest. He became interested in the problem of calculation and wrote a thesis on the subject under the direction of Maurice d’Ocagne (who died very shortly after it was accepted in March 1938). This was the first time that the topic of calculating machines had been accepted for a thesis at the University of Paris. This volume is that thesis. Evidently it was intended to be augmented by work on the topic of map (or graph) colouring, as mentioned as the second thesis on the title page. However, that thesis is not actually included in this volume. The bulk of the work consists of a description of mechanical calculating machines and a discussion of the binary number system. Couffignal proposes both mechanical and relay implementations of the binary functions.
