The cipher Aktiengesellschaft (short: ChiMaAG ) was a 1923 to 1934 existing German company, the key machine Enigma developed and manufactured. Your successor from 1934 was the cipher machine company Heimsoeth und Rinke (short: H&R ), which existed until the end of the war in 1945 .

ChiMaAG

The trading machine (1923) was the first in a long series of models

The company was founded on July 9, 1923 in Berlin ( W 35 , Steglitzer Str. 2, today Pohlstrasse , 10785 Berlin- Mitte / Tiergarten ) by the mining trade union Securitas , which had its headquarters at the same address. The company Scherbius & Ritter , which the German inventor of the Enigma, Arthur Scherbius (1878–1929), founded together with Ernst Richard Ritter in 1920, can be seen as a further forerunner . Both were on the board of the newly founded company, Scherbius 1927 and 1928, Ritter 1928 to 1931. The main purpose of ChiMaAG was the further development, production and commercial marketing of the cipher machine invented in 1918 (see also: Enigma patents ). This is where the early Enigma models such as the “ trading machine ”  (picture) , the “ Writing Enigma ”, the Enigma-A , Enigma-B , Enigma-C , Enigma-D and Enigma-H were manufactured. According to Friedrich L. Bauer , Willi Korn joined ChiMaAG as an important employee (chief engineer) in 1929. His invention of the reversing roller for the Enigma dates back to March 21, 1926.

The name and the legal form were changed to "Chiffriermaschinen Gesellschaft Heimsoeth und Rinke oHG" (short: H&R) in accordance with the law on the conversion of corporations of July 5, 1934, and the development and production of the machine continued. Rudolf Heimsoeth and Elsbeth Rinke , who were already involved in ChiMaAG, managed the company based in Uhlandstr. 136 in Berlin-Wilmersdorf.

Business activity was continued under the new company “Cipher Machine Company Heimsoeth und Rinke  oHG ”, or “Heimsoeth & Rinke” (H&R) for short. Due to the armament of the Wehrmacht , the production numbers rose sharply. Around 40,000 Enigma machines had been manufactured by 1945. During the war, this was not only done by H&R itself, but also under license from other plants, such as Olympia Büromaschinenwerke AG in Erfurt, the Ertel plant in Munich and Atlas Werke AG in Bremen. The main production plant for H&R at that time was Konski & Krüger (K&K) in Berlin-Mitte, Chausseestrasse 117.

From 1940, all of which carried Wehrmacht equipment supplied as weapons, ammunition, explosives, communications engineering device, etc. on the case or on the nameplate as a mark of origin one of three (from January 1941) lowercase existing coded manufacturing license plate instead of the manufacturer to the war opponents insights into the To deny suppliers or production facilities and thus make espionage and sabotage more difficult or prevent them. In the case of H&R, it was the production code jla . In May 1945 the company ceased operations.
