Hans Mauch

[3] In 1938 the Ministry re-organized its various internal departments, and in April Mauch took over the Special Development Division, which worked on JATO-type applications.

In August he met Helmut Schelp, who was working on jet engines in the Ministry's technical division (the T-Amt).

[5] The two approached the traditional engine companies in order to convince them to buy these efforts, but found a mixed reception until considerable funding was offered.

[8] When the war ended, the US Army Air Force brought many aviation engineers, including Mauch and Henschke, to Heidelberg.

While there, the two wrote a major chapter on human factors and cybernetics entitled "How Man Controls" in a two-volume work on German Aviation Medicine - World War II.

[3] However, they had little time to work on prosthetics during this period, and had to form a group to continue their research at night and on weekends with a Veteran's Administration grant.

Mauch also developed a similar artificial ankle that was described as revolutionary and that it "levelled the world" by adapting to irregularities in the ground, but given small volumes available the system was never able to be built in a form that was reliable enough for release.

[10] The company also introduced the Sterotoner, an early text-to-speech device for the blind, worked on human factors research, and developed an advanced spacesuit for NASA and the US Air Force.
