This book investigates the historical development of X-ray crystallography by documenting the contributions of its early pioneers and the technical evolution of structure determination. André Authier, a distinguished physicist in the field, utilizes historical records and scientific archives to reconstruct the methodology and intellectual climate of the early twentieth century. The text argues that the transition from theoretical physics to practical structural analysis was driven by specific collaborative efforts and incremental breakthroughs in diffraction techniques.

Experts recognize this work as a definitive historical account of the foundational period of crystallography. Readers frequently note the academic density of the prose, which serves as a valuable resource for students and researchers interested in the history of physical sciences.
