"Simpler and therefore better." Tessloff Verlag's credo says it all. It was coined by Ragnar Tessloff, who founded the publishing house for children and young people in 1956. Today, Tessloff Verlag is one of Europe’s leading publishers of non-fiction books for children and was awarded the German Publishing Prize in 2020. Tessloff is also the first children's and young people’s book publisher to report non-financial performance indicators in accordance with the German Sustainability Code (DNK) and is committed to climate protection and environmental education as well as social issues such as the promotion of reading and democracy.
Tessloff wants to inspire children with knowledge, and encourage them to use it to help shape the future. The publisher wants children to go through life with self-confidence and to find their individual place in the world and in society. This self-image is the basis for the multimedia publishing program, which introduces kids of all ages to factual knowledge in a playful way – of the highest standard, simply explained, and always at eye level.
With the brands WAS IST WAS, WAS IST WAS Junior and WAS IST WAS Meine Welt, the publishing house has created brands that are already published in 45 languages and more than 100 countries. WAS IST WAS has become a cult brand in the children's book segment, offering knowledge transfer for different age groups and in different media formats - from books, quiz books and puzzle books to the WAS IST WAS online presence and radio plays. The series WAS IST WAS Erstes Lesen and WAS IST WAS Erstes Lesen easy! provide factual knowledge specifically tailored to the needs of early readers in elementary school and offer didactically sound support for learning to read, one of the most important skills. The new thematic reading puzzles in the series are Tessloff's answer to IGLU and PISA.
WAS IST WAS has also established itself as a strong brand in the digital world. With the Alexa skill "WAS IST WAS Quiz", you can playfully become an expert in areas such as technology, animals, space, etc. Since 2021, the vast world of knowledge from WAS IST WAS has also been available as a podcast. With over 1.8 million downloads, it is one of the most popular audio formats in the "Kids and Family" category.
Tessloff Verlag has also been a very successful publisher of knowledge-based children's literature for several years. In the series Der kleine Major Tom (Little Major Tom), based on an idea by singer Peter Schilling, everything revolves around the adventures in space and on Earth of the likeable main character Tom, his girlfriend Stella, and the smart robot cat Plutinchen. A wide range of products has been created around the popular little astronaut, including radio plays, party accessories, clothes and calendars. In his successful series Der Kleine Mediziner (The Little Medic), the well-known physician Prof. Dr. Dietrich Grönemeyer combines action-packed adventure stories with useful knowledge about the human body and health. Since 2023, Benjamin Schreuder's ZeitBande has been publishing a children's detective series in a historical setting that combines historical background knowledge into an exciting package. The #Datendetektive book series by Jaromir Konecny takes an entertaining look at the topics of artificial intelligence and robotics.
Individual titles such as "Biomes of the World" and "How Much Rainforest Fits on This Bread?”, with a strong illustrative approach to knowledge transfer, complete the book portfolio.
The successful Fit for School series, popular with schoolkids, parents and teachers alike, makes the learning process easy and fun. While the "Learn and Understand" booklets explain and repeat school material, the varied exercise books, test booklets and 5-minute blocks allow students to practice and consolidate what they have learned in a playful way.
Another mainstay of the Tessloff programme is activity books for preschool and elementary school children. These include coloring and sticker books as well as a colorful selection of board books for children from 0 to 36 months.
With the BOOKii digital audio pen, Tessloff has successfully bridged the gap between the analog world of print and the digital age. BOOKii allows children to explore books with their eyes and ears. They simply tap the tip of the digital audio pen on pictures or text and original sounds are heard, characters begin to speak, or text is read aloud.
