<abstract>
<p>The year 2012 marks the 100th anniversary of the discovery of cosmic
radiation by the Austrian physicist Victor Franz Hess (1883&amp;ndash;1964), obtained
onboard manned balloons, one of them launched up to an altitude of 5.3 km.
His discovery earned him the Nobel Prize in 1936. The discovery follows in
the context of the investigation of atmospheric electricity and of the newly
discovered radioactivity, in particular with respect to &amp;gamma; rays.
Starting from simple ionization chambers, the instruments were developed
during an interplay between functional requirements, scientific progress and
available manufacturing technologies.
&lt;br&gt;&lt;br&gt;
The authors of this contribution take this anniversary as an opportunity to
describe the instrumentation used by Hess, as well as further developments
in the instrumentation which took place in the decades following Hess&apos;
discovery. This manuscript also discusses details of the company who
manufactured Hess&apos; instrument, &apos;&apos;Günther &amp; Tegetmeyer&apos;&apos;
based in Braunschweig, Germany. This company did not only build instruments
for Hess and the research on cosmic rays, but also for other scientific
disciplines and for well-known researchers and discoverers.</p>
