Klemm
German aircraft manufacturer
The Klemm Leichtflugzeugbau GmbH ("Klemm Light Aircraft Company") was a German aircraft manufacturer noteworthy for sports and touring planes of the 1930s.
The company was founded in Böblingen in 1926 by Dr. Hanns Klemm, who had previously worked for both Zeppelin and the Daimler Aircraft Company.
History
While working at Daimler, Klemm had developed his ideas for a light aircraft, to be made of wood for strength and lightness. It should be easy to manufacture, aerodynamically efficient with low mass and wing loading, for which a low-powered engine would be sufficient. Klemm's first design, the Daimler L.15, was a light aircraft with a single 7.5 hp (5.5 kW) Indian motorcycle engine. This aircraft flew in early 1919, although a 12 hp (8.8 kW) Harley-Davidson engine was used instead of the originally-envisioned engine.
Klemm then designed a squared-off version of the cylindrical fuselage of the L.15, which could be more easily built, which he designated the L.20, and he founded his own company to produce it. This aircraft, of which more than 100 were built, was powered by a 20 hp (15 kW) Daimler engine designed by Ferdinand Porsche.
In 1928 Friedrich Karl von Koenig-Warthausen made a solo flight to Moscow in a Klemm L.20, then decided to keep on going, circumnavigating the world and earning himself the Hindenburg Cup, the highest German honour for aeronautical achievement.
This brief starts where responsible research should: with the source description of “Klemm” as german aircraft manufacturer. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as german aircraft manufacturer. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 12, 2022. The linked authority identifier is Q1584666. The first chronological checks are 1926, 1919 and 1928.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
