Litkenhous Ratings
The Litkenhous Difference by Score Ratings system was a mathematical system used to rank football and basketball teams. The Litrating system was developed by Vanderbilt University professor Edward Earl ("E.E.") Litkenhous Jr. (1907 – December 22, 1984) and his brother, Francis H. Litkenhous (December 9, 1912 – June 22, 1996).
Edward Litkenhous (1907-1984) received an undergraduate degree from the University of Louisville and a doctorate from the University of Minnesota. He began his career as a professor of chemical engineering at the Speed Scientific School of the University of Louisville. He later became a professor at Vanderbilt University and served as head of that school's engineering department. He died in 1984.
The National Collegiate Athletic Association (NCAA) football records book includes the Litkenhous Ratings as a "major selector" of college football national championships for the seasons 1934 through 1984.
