Presented at the American Society of Mechanical Engineers, Atlantic City, New Jersey, November 29, 1951. (PDF; 85 pages; 36.1MB)

Additional information on the author of the technical paper: Eugene W. Kettering, son of Charles F. Kettering, joined Winton Engine in 1930. He moved to Detroit in 1936, and was a central figure in the development of the 567 and the Detroit Diesel 6-71. He moved to EMD in 1938, became Chief Engineer at EMD in 1948, then Director of Research in 1955 and subsequently Research Assistant to the General Manager in 1958. He resigned from EMD in 1959 to manage the Kettering family's interests in the various foundations established by Charles F. Kettering. Eugene Kettering passed away in 1969. (Preston Cook, posted to Railway Preservation News, June 29, 2013)

In 1930, Eugene W. Kettering joined General Motors as a research engineer, and he became a leading figure in the in the evolution of the modern diesel locomotive. After nearly 30 years with General Motors, Eugene Kettering retired and he and his wife, Virginia, devoted their energies to a wide range of philanthropic activities. When the Air Force Museum Foundation was created in 1960 to fund the building of a new Air Force Museum, Kettering continued his family's interest in aviation and became the foundation's first chairman. He actively assisted in raising funds to construct the Air Force Museum, which opened in 1971. Kettering supported the museum in many other ways, including the long-term loan of 558 model airplanes from his personal collection in 1962. The models on display give visitors a sense of the technological growth of aviation in a glance.
