This 15 kw (20 shp) horizontally-opposed, air-cooled engine was built by L. Dutheil and R. Chalmers and Company of Paris, France, about 1910. An engine similar to this type powered Santos-Dumont's Demoiselle aircraft.
Matthew B. Sellers, builder of the first Kentucky-manufactured aircraft, flew his first quadraplane from 1908 to 1913 powered by various 2-cylinder, horizontally-opposed engines. This Dutheil-Chalmers was one of these engines.
