Siemens & Halske
Siemens is a German manufacturer of electronics equipment.
It is currently Europe's largest engineering conglomerate with headquarters
in Berlin, Munich and Erlangen (Germany).
Siemens was founded in 1847 by Werner von Siemens as
Telegraphen-Bauanstalt von Siemens & Halske.
Before and during WWII, Siemens built equipment for the German Department
of Defense (DoD), such as the famous
T-52 Geheimschreiber.
After the war, Siemens produced cipher machines
for NATO and its allies, some of which were developed in cooperation
with Philips
and Crypto AG.
Over the years, the Siemens logo changed a number of times. The one shown
at the top is the 1935 design, featuring a merged 'S' and 'H' in a circle.
It was derived from the 1899 version that had no circle.
In 1936, the circle was abandoned again and the word SIEMENS was written
in red under the logo. In 1973, the logo was dropped in favor of the
written version of 'SIEMENS'. In recent years, the word SIEMENS was
replaced by a more modern typeface, as shown above.

Note that some of this equipment was (partly) developed by
Crypto AG themsemves or by the Government
Electronics Division of Motorola.
In case of the H-460,
Siemens only fixed design issues to that it could be re-released.
In other cases, the cryptologic was developed by ZfCh and
implemented by Siemens.
