Overview

NorthSouth Books is the English-language and internationally oriented identity associated with the Swiss children's publisher originally founded as Nord-Süd Verlag. Established in Zürich in 1961 by Dimitrije Sidjanski and Brigitte Sidjanski, the company was created around the idea that children's books could encourage communication across languages and cultures. Its early publishing program reflected that ambition through multilingual editions, international rights activity, and books created by authors and illustrators from different national traditions. The company's first publication was The Clown Said No, written by Dimitrije Sidjanski under a pseudonym. From its early years, the house concentrated on illustrated children's literature rather than building a broad adult-trade list. During the 1960s and 1970s it developed a reputation for carefully produced books and worked with creators including Janosch, Ralph Steadman, and Bernadette Watts. Translation, licensing, and the circulation of books across national markets became central to its identity. This international orientation also allowed the publisher to introduce European and other foreign-language children's works to English-speaking readers. NorthSouth's best-known property is Marcus Pfister's Rainbow Fish, first published in 1992. The picture-book series combined a simple story about sharing and community with illustrations using iridescent foil, giving the books a distinctive physical appearance. Rainbow Fish became a major international children's publishing success and established NorthSouth as a recognizable source of illustrated picture books in the United States and other English-language markets. The company has also been associated with Hans de Beer's Little Polar Bear series and with titles by creators such as Max Velthuijs, Ralph Steadman, Janosch, Bernadette Watts, and Marcus Pfister. The English-language NorthSouth Books imprint developed under the leadership of Davy Sidjanski, the founders' youngest son, who helped expand distribution in the United States. The company has operated through a Swiss base and an American publishing presence, with distribution and publishing relationships supporting English-language editions. Partners cited in connection with its English-language activity include Henry Holt & Co. and Faber & Faber. The publisher has also used the Ediciones Norte-Sur imprint to serve Spanish-speaking readers. The company experienced a restructuring after being acquired by private investors in 2004. In 2012, Oetinger Publishing Group acquired a majority stake, bringing NorthSouth into a larger German publishing group while retaining the Zürich operation and its international orientation. After that transaction, the company continued to publish and acquire original and translated children's books, including works by American authors and illustrators and English-language editions of international titles. Examples associated with the later catalog include Jon Klassen's I Want My Hat Back and This Is Not My Hat, Ken Kimura and Yasunari Murakami's 999 Frogs Wake Up, Matthias Weinert's No Bath, No Cake, and Marcus Pfister's The Yellow Cab. NorthSouth Books remains positioned as an internationally minded children's publisher. Its catalog combines original picture books, translated and licensed titles, series publishing, and visually distinctive books intended for family reading and early readers. The house's principal differentiation is not a single format or educational method, but the combination of cross-cultural rights work, illustrator-led storytelling, and high-quality picture-book production.

History

NorthSouth Books traces its origins to Nord-Süd Verlag, founded in Zürich in 1961 by Dimitrije Sidjanski and Brigitte Sidjanski. The founders established the company as an internationally minded children's publisher at a time when multilingual publishing and the circulation of illustrated books across borders were central to its identity. Its first book, The Clown Said No, was written by Dimitrije Sidjanski under a pseudonym. The early program was shaped by the belief that children's literature could promote understanding between cultures, a principle reflected in the company's choice of authors, illustrators, translations, and international rights. During the 1960s and 1970s, Nord-Süd Verlag built recognition for well-produced children's books and worked with creators including Janosch, Ralph Steadman, and Bernadette Watts. Rather than limiting itself to domestic Swiss publishing, the house acquired, translated, licensed, and distributed works from a range of cultural backgrounds. This approach helped it develop an international catalog and gave the company experience in adapting illustrated books for multiple language markets. The publisher's later growth was closely connected to its English-language business. Under Davy Sidjanski, the founders' youngest son, the company expanded distribution in the United States and developed the NorthSouth Books imprint. The imprint became the principal English-language identity for many of the company's international titles. NorthSouth's catalog grew through a mixture of original publishing, translation, licensing, and reissues of established children's classics. A decisive commercial and cultural turning point came in 1992 with Marcus Pfister's The Rainbow Fish. The book's story about sharing and belonging was paired with illustrations incorporating iridescent foil, creating an unusually tactile and visually recognizable picture-book format. The title and its sequels became the company's most prominent international property. NorthSouth also became associated with Hans de Beer's Little Polar Bear books, as well as works by Max Velthuijs, Ralph Steadman, Janosch, Bernadette Watts, and other internationally published creators. The success of these books strengthened the house's reputation in illustrated children's literature. In 2004, NorthSouth was acquired by private investors and underwent restructuring. The change marked a shift from the founders' family-centered ownership model toward a reorganized corporate structure. In 2012, Oetinger Publishing Group acquired a majority stake. Oetinger, a major German children's publisher, provided a larger group structure while NorthSouth retained its Swiss base and international publishing identity. The transaction also supported closer cooperation between the Zürich office and the U.S. imprint. After the Oetinger transaction, NorthSouth continued to broaden its catalog. It published original works by American authors and illustrators, acquired English-language rights to internationally recognized books, and maintained a Spanish-language presence through Ediciones Norte-Sur. Titles associated with this period include Jon Klassen's I Want My Hat Back and This Is Not My Hat, Ken Kimura and Yasunari Murakami's 999 Frogs Wake Up, Matthias Weinert's No Bath, No Cake, and Marcus Pfister's The Yellow Cab. Distribution relationships involving Henry Holt & Co. and Faber & Faber helped place English-language editions in relevant markets. Today, NorthSouth Books operates as an active children's publishing brand within the Oetinger Publishing Group. Its business remains focused on picture books, illustrated series, international rights, translations, and editions designed for readers in multiple markets. The publisher's historical continuity lies in its cross-border approach: it connects creators, stories, and audiences across languages while preserving a strong emphasis on illustration and physical book design.
