The 'WAS IST WAS' brand is an iconic German educational series founded in 1961 by the Tessloff Verlag. It was modeled after the American 'How and Why Wonder Books' but quickly became a uniquely German cultural staple. The books are primarily authored and printed in Germany, targeting young readers with scientific and historical facts. The brand remains under the ownership of the original founding family's company, Tessloff Verlag, which continues to be a leading publisher in the German-speaking market.
