Franckh-Kosmos Verlags-GmbH & Co. KG (formerly Franckh'sche Verlagshandlung, W. Keller & Co.) is the name of a Stuttgart-based publishing house, which has made a name for itself through nature guides, guides, technical, children's and youth books and experiment boxes Has. The company is also active as a game publisher. One of the most famous titles in the game program is "The Settlers of Catan".

The publishing history

1822:  Johann Friedrich Franckh founds the Franckhsche Verlagsbuchhandlung. Initially, the publishing program was characterized by literary writers such as Wilhelm Hauff, whose fairy tales, such as "The Cold Heart" or "Dwarf Nose", and folk songs are still known today.

1893: Walter Keller and Euchar Nehmann take over the publishing house

With the rapid development of the natural sciences, the focus of the publishing house changed at the end of the 19th century. Under the motto "Understanding Science", the first guides and non-fiction books on popular science topics developed with the "KOSMOS Handweiser für Naturefriends".

The KOSMOS publishing house

Franckh-Kosmos Verlags-GmbH & Co. KG, KOSMOS Verlag for short, is a media company in the heart of Stuttgart that feels equally committed to tradition and modernity. Our program covers a broad spectrum: guides, nature guides, non-fiction books, cookbooks, DVDs, children's and teen books, games, experiment kits, e-books and apps.

Well-known products and brands

Who does not know them, the KOSMOS experiment boxes or well-known brands and products that have received multiple awards such as What is blooming there ?, What's flying there ?, Catan, The three ???, The three !!! or star tail? 
Committed and motivated by success: We know what our customers and our target groups expect from us. That is why more than 700 authors develop our innovative products; Together with approx. 20,000 trade customers, our business partners and our employees, they are our greatest potential.

The KOSMOS family and board games

The high quality in terms of features, design and playful standards has made KOSMOS one of the most successful games manufacturers of recent years. Catan (awarded the Game of the Year 1995) are an integral part of the gaming landscape. 
Our concept "Literature in the Game" has shown, for example, that "The Pillars of the Earth" do not only know how to inspire in book form. The awards for our "Game of the Year" products (2008 for Keltis or 2013 for The Legends of Andor) or the "Children's Game of the Year" (2005 for The Little Ghost) show that we are exactly right with this commitment. Our games are played in many countries around the world and have helped to establish the success of the German Games in the USA.

The KOSMOS experiment boxes and access to knowledge

Generations of children have discovered their enthusiasm for science with the KOSMOS experiment kits. KOSMOS stands for innovation and quality as well as safety in the execution of the experiments. We believe children can better understand processes through active experimentation and are thus able to "experience and understand the world". 
In addition to the updated classics on the topics of chemistry and electronics, the young generation hungry for education can now also deal with wind energy or solar energy.

The KOSMOS quality

KOSMOS is and remains the guarantor for highest book and game quality - this applies to the content and the product. This is not coincidental, but is the result of our strategy. We use globally operating specialists and make sure that the production conditions meet our standards and are certified by specifications and on-site visits. We know what our customers want, because of course our products are tested by the target group before they reach the market. Our authors and collaborators are experts in their field and are usually themselves part of the target audience for whom they think, write and be active. KOSMOS books and games are not just for the moment. Although they are entertaining, they are durable and sustainable.
