The New International Encyclopædia/Reuleaux, Franz

REULEAUX, , (1829— ). A

German mechanical engineer, born at Eschweiler, near

Aix-la-Chapelle, where his father had machine

shops. After finishing his apprenticeship in

Koblenz, he worked in his father's shops, studied

at Karlsruhe, and for a year was head of a

factory in Cologne. Then he taught in Zurich

(1856-64) and in Berlin (1864-96), where from

1868 until retirement he was director of the

Industrial School. Reuleaux was intimately

connected with German machinery exhibits at

Philadelphia in 1876 and at Sydney and

Melbourne (1879-81). His Briefe aus Philadelphia

(1877) voice a sharp criticism on German methods

of construction and especially on the lack of

artistic design. To remedy this fault Reuleaux

gathered a great collection of kinematic models

in Berlin. His works are: Konstruktionslehre

(with Moll, 1854-62); Der Konstrukteur (1860-62, and often); Kurzgefasste Geschichte der Dampfmaschine (1891); and Thomassche Rechenmaschine (2d ed. 1892).
