George Eastman (1854-1932), was an ingenious man who contributed greatly to the field of photography. He developed dry plates, film with flexible backing, roll holders for the flexible film, a Kodak camera (a convenient form of the camera for novices), and an amateur motion-picture camera. Through his experimental photography, he accumulated a large sum of money. His philanthropic personality prompted him to give his money to various business endeavors, including the University of Rochester.

The stolen machine is one of the Enigmas used by the German military intelligence service - Abwehr. There probably are more than three of these machine left but they are extremely rare and I would not be astonished to find that only a handful remain in existence. The only other machine of this type we know about in a museum with public access is in the National Cryptologic Museum, at Fort Meade, MD, USA.
