Braunschweig: Friedrich Vieweg und Sohn, 1875 and 1900. First edition. Text in German. Two volume set, well illustrated. Franz Reuleaux (1829-1905), often called "the father of kinematics," was a mechanical engineer and President of the Berlin Royal Technical Academy. FIRST VOLUME: Erster Band: Theoretische Kinematik; Grundzuge einer Theorie Des Maschinenwesens [Theoretical Kinematics, Basic Course of a Theory of Mechanical Engineering]; 622 pages including index; 452 illustrations in the text; 8 double-page folding tables. SECOND VOLUME: Zweiter Band: Die Praktischen Beziehungen der Kinematik Zu Geometrie Und Mechanik [The Practical Relations of Kinematics to Geometry and Mechanics]; 788 pages including index; 670 illustrations in the text; two folding illustrations. Freshly rebound in gray cloth boards with page edges marbled, new endpapers added, and gilt-lettered brown leather labels on spine. Please note: both volumes have been re-bound in such a way that the folding plates have been bound in (i.e., though all of the folding plates are completely viewable, it is difficult to see the areas at the inner hinges). Some minor foxing to volume 1 but none in volume 2. A near fine set. Both volumes are scarce in the original editions -- the 2nd volume, published 5 years after the first, is especially so.
