Prof. Kahn was a frequent guest lecturer in my Airline Management Class at the Hotel School at Cornell. (HA 409). He was a gracious man, of encyclopedic knowledge of the metrics of the airline business, and always exhibited enormous interest in and patience with all of the many questions posed to him by my students. In private life he was a committed amateur thespian, and my wife and I had the privilege of seeing him perform at Ithaca High School and Ithaca College. The world is a better place for his having been here, and he will be sorely missed. I offer my deepest condolences to Mrs. Kahn and the family.
