Deutsch: Rechenschieber, System Darmstadt
English: Slide rules, system Darmstadt:
In 1934, the German mathematician and engineer Alwin Walther at the Technische Hochschule Darmstadt modified and enhanced the System Rietz for the needs of engineers: A Pythagorean scale (P) was added on the front. The mantissa scale (L) was transferred to the rear and the sine and tangent scales (S, T) to the front. The back side of the slider was now free for the exponential scales (LL). This System Darmstadt became the base model for all the following improvements.[1]
