Overview

Bertram + de Leeuw (formally Bertram en De Leeuw uitgevers) is an independent Dutch-language non-fiction publishing house based in Haarlem, the Netherlands. It was founded in July 2010 by Marij Bertram and Hendrik de Leeuw, two publishing professionals who had previously been involved in setting up the Amsterdam publisher Nieuw Amsterdam five years earlier and who had worked together for many years at VBK Uitgevers. The company was originally established in Amsterdam and relocated to Haarlem in 2015. In 2019 Marij Bertram stepped back from the business and Emile Blomme took over her share. The publisher focuses on commercial non-fiction, with a catalogue that spans culinary books, lifestyle titles and management literature. Its list includes works by authors such as Thomas Rau, Marianne Zwagerman, Annemarie van Gaal, Marc Lammers, Mascha Feoktistova and Pierre Wind. The official website highlights titles including "Only Planet: Klimaatgids voor de 21e eeuw" by Tim van Hattum, "Lekker & Simpel" (celebrating its tenth anniversary with 150 favourite recipes), "Van aardappel tot zeewier" by Eke Mariën and Annemarie Coopman, and e-books such as "Duurzaam kapitalisme", "De hamster in je brein" by Felix Kreier and Maarten Biezeveld, and "Keerpunt 1971" by Edin Mujagic. Upcoming titles include "Kookboek voor mijn 8 broers" by Coosje Kruijsen. As a small, independent publisher, Bertram + de Leeuw operates in the Dutch-language market, serving readers in the Netherlands and Flanders. It maintains a modest office presence, with the website listing an address at Prinseneiland 43 in Amsterdam alongside its Haarlem base. The company positions itself around accessible, commercially oriented non-fiction that combines practical value with broader cultural and societal themes, from climate guides and sustainable capitalism to personal development and cookery.

History

Bertram + de Leeuw was founded in July 2010 by Marij Bertram and Hendrik de Leeuw. Both founders had previously been involved in the creation of the Amsterdam publisher Nieuw Amsterdam five years earlier, and before that they had worked together for many years at VBK Uitgevers. The new publishing house was initially based in Amsterdam and focused on Dutch-language non-fiction. In 2015 the company moved its base to Haarlem. In 2019, Marij Bertram stepped back from the business and Emile Blomme acquired her share in the publisher. The company has continued to operate as an independent non-fiction publisher, building a catalogue of culinary, lifestyle and management titles by authors including Thomas Rau, Marianne Zwagerman, Annemarie van Gaal, Marc Lammers, Mascha Feoktistova and Pierre Wind. Its website lists both a Haarlem office and an address at Prinseneiland 43 in Amsterdam, and highlights recent and forthcoming titles such as "Only Planet: Klimaatgids voor de 21e eeuw", the tenth-anniversary edition of "Lekker & Simpel", "Van aardappel tot zeewier", and e-books including "Duurzaam kapitalisme", "De hamster in je brein" and "Keerpunt 1971".
