The 220 models in Cornell University's Reuleaux Collection were built in the late 19th century to demonstrate the elements of machine motion, as theorized by the German engineer Franz Reuleaux. The University acquired the models in 1882 for use in teaching and research. This is KMODDL's core collection and at present is the most extensively documented and enhanced with multimedia resources.
