User keywords, or 'tags', are words added to object records by other users to enhance their discovery. You can add keywords that may be useful in helping others find this object.

We are experimenting with tagging because sometimes museums describe objects in language that is highly specialist and user added keywords are useful in bridging the 'semantic gap' between the language of the museum and that of the user.

Any keywords listed have been added by other users like yourself. You can click on them to use them as search terms to dicover other objects. User tags
Related subjects lists the broad themes that have relevance to the object you are viewing. You can click these themes to see other objects related thematically. Related Subjects

'Autogenerated tags' are a new feature that we are testing. These tags are generated by passing the object record through the OpenCalais service from Reuters. This service makes a 'best guess' at the names, places, companies and specialist terminolgy that is in the text of the object records.

By clicking on a tag you can find all other collection records related to that person, place or company.

Because the tags are autogenerated there are likely to be some errors. If you spot one of these then please flag the tag for deletion by clicking the 'x'. Auto-generated tags: [Beta]

Production Notes include information about the design, manufacture and marketing of an object. Production notes
Original design by German engineer Arthur Scherbius. It was then modified by the Wermacht (German army), names of the later designers are unknown.

The commercial machine was made by the Chiffreirmachine Company of Berlin and it quite probable that the Wehrmacht machines were made, or at least assembled, there. This cannot be verified at this stage.

The first Enigma machine was patented in 1919 but was continually modified until the end of World War II.

Description
Cipher machine, Enigma, wood / metal / Bakelite, Chiffreurmachine Company, Berlin, Germany, 1940.

Wehmacht (German army) type in a dark beige painted metal casing. The top consists of three 1 - 26 numbered rotors, a Bakelite switch with two options, and a keyboard of letters in the configurations: QWERTZUIO, ASDFGHJK, PYXCVBNML the keys are made of metal and black Bakelite with white letters. The display/or lamp board above shows same letters, this can be lifted by unscrewing two round nuts located on the sides of the display board to reveal three rows of lamps which light up the letters, three numbered wheels and switching gear. On the front face of the housing is a plug board with connector holes for each letter and ten connector cables which are plugged into various letters.

The whole assemblage fits tightly into an oak carry case with a hinged lid and fall front which is secured by way of two small metal hooks on the sides of the case, and a metal fold-in handle. Inside the lid is a white Bakelite label with German text printed in black, two spare plug cables 3 spare bulbs and a strip of black Bakelite screwed onto the lid.

Depressing the key for a given letter causes a signal for that letter to pass through the three rotors and the plug board. This operation causes a cascade of substitutions for the original letter. In this manner a message can be coded that can only be retrieved by being played back through the same sequence of substitutions.
