REULEAUX, Le constructeur, 1890

Franz Reuleaux (1829-1905) was a German mechanical engineer, professor at the Berlin Polytechnic, considered the "father of modern kinematics." His work Le constructeur (The Constructor) is a fundamental technical manual for machine design, highly influential in the late 19th century. It provides principles, formulas, drawings, and tables necessary for engineers, constructors, and mechanics. The French translation by A. Debize, chief engineer of State Manufactures, based on the fourth German edition (fully revised and augmented), testifies to the international importance of Reuleaux's work and his role in disseminating knowledge in mechanical engineering.
