Celebrity Class M Phonographs
I have closely examined two Class M phonographs which were presented by Edison to German celebrities in 1890. Both were regular production models, each the latest type of machine, one with a mahagony case, the other with an oak case. The one presented to Hermann von Helmholtz had a brazen name plate with an engraved dedication from Edison, the second, presented to Matilda Rathenau had a small metal frame attached, holding an autograph by Edison. A book under my coauthorship about these and a good number of other phonographs will hopefully be published early next year. I keep you posted.
Military Phonograph
For some time I had intended to write about the military phonograph, but other duties kept me from this project. In short, the idea for a portable phonograph came from George Edward Gouraud, Edison's representative in Great Britain. On November 3, 1888 Gouraud wrote to Edison:
PORTABLE PHONOGRAPH FOR EXPRESS SERVICES – CIVIL & MILITARY. - I confirm my letter of 6th October with reference to the mounted phonogram express service which I am inaugurating in this country, and I now beg to inform you that I have begun a systematic course of applications for concessions generally throughout the entire territory under my direction, and am hoping to, at least in some cases, succeed, and am anxious to include, if possible, the exclusive right of Phonograph Talking Stations in the Depots and Passenger Stations of the Railway Companies. I would therefore here again urge upon you the extreme advisability of giving your earliest attention to the devising of some special portable machine for this messenger or phonogram express service, which machine would be equally adapted to military purposes, and for which I can assure you of an enormous demand; in fact I am in a position to say that if such a portable instrument can be devised, I am prepared to give you an order for 10,000.
Please give your early attention to this matter as it interests me greatly, and your advice will be highly appreciated.
Edison quickly responded, underestimating the task: Say I am making a ⅛ size phono complete will send photograph in week or two.
Six months later, the military phonographs(!!), scheduled for the Paris exposition still waited for completion, which is apparent in a letter from Edison to the Edison Phonograph Works on May 6, 1889: Mr. Hammer writes, requesting us to hurry up the Military Phonographs and forward them to Paris as soon as possible.
The term "military phonograph“ last showed up in my files for October 1889. William Joseph Hammer, Edison's representative in Paris wrote to Jonathan Lewis Young: You had better postpone your book till you get some photos and matter I am having made for you and if you can run over to Paris I can give you some valuable data. I have just had interesting photos made of Edisons original phonograph, his perfected tin foil machine and his new treadle latest type. … talking doll, military phonograph and arrangement of all. There is a picture of the talking doll listening to the phonograph &c.
PS: I checked it again, Edison indeed wrote "⅛ size".
