Quarto Partners managing director David Inman announced that he will leave the U.K.-based illustrated book publishing Quarto Group at the end of February.

Quarto CEO Marcus Leaver praised Inman’s tenure, describing it as an “invaluable contribution to Quarto,” and noting that “he did an excellent job sorting out our U.K. trade businesses and opening up new opportunities.”

Inman was Quarto Partners’ U.K. sales and marketing director from 2009-2011, with responsibility for the company’s foreign language co-edition business, after which he left the company. Inman rejoined Quarto in 2013 as its managing director, overseeing Quarto distribution services and its international publishing partnerships.

Leaver credited Inman with growing the company’s international children’s publishing via Quarto’s Frances Lincoln Children’s Books and Wide Eyed Editions imprints. In addition, Inman is credited with key appointments that transformed Quarto’s U.K.-focused Aurum Press into an international illustrated publishing line.

Inman was also cited for his work organizing Quarto’s international distribution agreements in Australia and New Zealand and negotiating agreements in Spain, Latin America, and North America for Quarto Iberoamericana, Quarto’s Spanish language imprint.

Inman described his tenure as “one of the most challenging and enjoyable chapters in my publishing career.” He added: “I would like to pay tribute, in particular, to the fantastic team who supported me at Quarto Publishing Group U.K.”

CORRECTION: This story initially misrepresented Inman's title as managing director of the whole of the Quarto Group. He is managing director of Quarto Partners, a division of the company.
