Dimitrije Sidjanski (also known as Mischa Damjan) was born in 1914 in Skopje, Macedonia (formerly Yugoslavia). He grew up in Belgrade and studied there before going to Paris to pursue a degree in law. Later he became a lawyer. In 1945 he escaped from captivity in Germany and fled to Switzerland, where he began to write short stories and novels. In 1949 he got to know his future wife, Brigitte Sidjanski, and in 1961 the two of them together founded NordSüd Verlag. In 1979 Dimitrije retired from the company in order to devote himself completely to writing. He died in 1998 at the age of eighty-four.

Torben Kuhlmann lives and works in Hamburg as a freelance children’s author and illustrator. He studied illustration and communications design at the Hamburg University of Applied Sciences. He wrote and illustrated his first picture book, Lindbergh: the Tale of a Flying Mouse, in 2012 as his final thesis, and it was published in 2014 by NordSüd Verlag. It quickly became a bestseller and has been translated into more than 30 languages. Three more mouse adventures followed and were equally successful. In 2024, the tenth anniversary was celebrated by the publication of Earhart, the fifth book in the series. However, a few mouse-free books have also crept into the repertoire during the last ten years, including Moletown, The Clown Said No, and The Gray City.
