✑ Henri Desarces

NOUVELLE ENCYCLOPÉDIE PRATIQUE DE MÉCANIQUE ET D'ELECTRICITÉ

Henri Desarces' "Nouvelle encyclopédie pratique de Mécanique et d'Electricité," published in 1924 by Librairie Aristide Quillet, represents a monument of scientific and technical popularization from the interwar period. This ambitious work bears witness to a pivotal era when the second industrial revolution was profoundly transforming French and European society. Henri Desarces, a recognized engineer and educator, conceived this encyclopedia as a practical tool for both professionals and autodidacts eager to master new technologies. The work is distinguished by its 15 rigid fold-out plates, true treasures of technical documentation that precisely illustrate the mechanisms, electrical circuits, and industrial applications of the era. These plates constitute a remarkable element of the edition, offering a visual dimension essential to understanding the concepts discussed. The encyclopedia covers the entire spectrum of mechanical and electrical knowledge: from motion transmission to combustion engines, from dynamos to domestic and industrial electricity applications. More than a simple technical manual, this encyclopedia represents a precious historical testimony to the state of applied sciences in the 1920s, a transitional period between the age of steam and that of widespread electrification.

Description

Historical and Editorial Context

Published in 1924 by the prestigious Librairie Aristide Quillet, this encyclopedia fits into a French editorial tradition of reference works intended to democratize scientific and technical knowledge. The post-war period represented a time of intensive reconstruction and modernization, where demand for practical knowledge in mechanics and electricity experienced exponential growth. Henri Desarces responds to this need with an exhaustive work that synthesizes knowledge accumulated since the late nineteenth century while integrating the most recent innovations.

Structure and Content of the Work

The encyclopedia is systematically organized, first addressing the fundamental principles of mechanics before progressing to increasingly complex applications. The sections dedicated to electricity cover both theoretical and practical aspects, from the fundamental laws of electromagnetism to industrial and domestic installations. The 15 rigid fold-out plates constitute one of the work's major assets: printed on superior quality paper, they present detailed technical diagrams, machine cross-sections, electrical circuits, and pedagogical illustrations that make the complexity of mechanical and electrical systems accessible.

Scientific and Pedagogical Significance

Henri Desarces' approach is characterized by a remarkable balance between scientific rigor and pedagogical accessibility. The author does not merely present abstract formulas and theories but strives to concretely explain how machines function, the principles of their design, and their practical applications. This pragmatic dimension makes the encyclopedia a valuable tool for engineers, mechanics, electricians, and all technicians of the era.

Historical and Documentary Importance

Beyond its original practical value, this work today constitutes a first-rate historical document for understanding the state of technology in the mid-1920s. It bears witness to an era when electrification of homes and industries was accelerating, when the automobile was beginning its democratization, and when machine tools were transforming production methods. The fold-out plates, true snapshots of the technology of the time, offer a fascinating glimpse into industrial standards, safety norms, and engineering practices from a century ago. For collectors, historians of science, and enthusiasts of technical heritage, this encyclopedia represents a precious acquisition documenting a pivotal period of the modern industrial revolution.
