Full interview with Frank Adorney about the conception, development and fabrication of the Hudson 8 and Hudson 9 slide rule.  This rule, invented by James R. "Pop" Bland, a mathematics professor at the U.S. Naval Academy, was the prototype for the famous Keuffel & Esser Deci-Lon slide rule.  Bland asked his former student Frank Adorney for help fabricating the initial mock-ups and working prototypes of his new rule.  This interview was conducted by Deborah Douglas, curator of science and technology at the MIT Museum on January 25, 2012 at the U.S. Naval Academy in Annapolis, Maryland.  It provides extensive background about the rules which are now part of the MIT Museum's collection.
