Herring-Curtiss Engine

1908 or 1909 Herring-Curtiss 4-stroke, 4-cylinder water-cooled aircraft engine designed by aviation pioneer Glenn Curtiss.  It has a Berling magneto and internal Ford Model-T car parts, including the crankshaft.  There’s a 1912 stamp in the front timing cover and “Herring-Curtiss” stamped on the oil pan/crankshaft cover.  Parts were probably switched from other engines because there is evidence of damage, such as a thrown rod or a broken crank.


This is one of the earliest aircraft engines ever made.  It was used by Curtiss in his Golden Flyer biplane, also known as the Curtiss No. 1 (the first aircraft both designed and built by Curtiss). Curtiss flew the Golden Flyer to win the Scientific American trophy in 1909.  Later that year, the Golden Flyer crashed and was badly damaged. The Museum’s engine arrived at OAM as a box of parts with the comment “I think it may be an airplane engine.”  The engine was restored and identified in 2010 by the Aviation Club at Los Altos (Ca) High School, under the guidance of Greg Ely, OAM Crew Chief and Museum Trustee.
