Historical documentation and articles

Hans Neufeldt and Karl Kuhnke founded the Kiel company Neufeldt & Kuhnke in 1899. Until 1936, the company stood for excellent and very durable technical products. Then the name was changed in the same year. Unfortunately, the previous brand was forgotten as a result.

We will share with you old and interesting reports from a bygone period in our company's history.

Cover page for doctoral thesis by Hans Usener

Dr. Hans Usener from Kiel was one of Neufeldt & Kuhnke's most important employees.

Many of the company's inventions, such as the legendary armored suit, were his credit and became popular thanks to him.

Here you can see the original cover page of his doctoral thesis, which fortunately has been available to us in full printed form since the beginning of May 2024.

Kutter

 

This cutter from 1910 was powered by an N&K Type II Z B 4 engine. As far as we know, the engine is a 1 or 2 cylinder hot bulb engine.
Previously it was assumed that N&K only started producing engines in the 1920s, but now we know that it was as early as 1910 N&K marine engines existed.

So we see here a particularly historically valuable document.
