Glenn L. Martin was one of America’s great aviation pioneers.  During his remarkable career he worked with a number of famous aircraft engineers, including Orville Wright.  Mr. Martin often attended the Indianapolis 500, and his company was a sponsor of the lap prize fund at Indy.  In late 1928 Martin teamed up with Louis Chevrolet in the development of Chevrolet’s 333 inverted aero engine, providing important financial and technical support.  The goal was to market a compact, reliable, and powerful engine for the growing sport aircraft segment.  Additionally the Martin Company had strong ties to the U.S. Military, and Louie’s engine showed promise for use in small training aircraft.  Unfortunately the onset of the Great Depression proved to be too much for this business venture.  Listed below are documents relating to Louis Chevrolet when he worked for the Glenn L. Martin Motors Company.
