Editor-in-Chief
Wm. B. Eerdmans Publishing Company

I first met Klaas Wolterstorff when I came to work for Eerdmans in 2015. I had used and admired Eerdmans books for years. I came to realize, over my first several months of working at Eerdmans, that Klaas was personally responsible for the high quality, in interior and exterior design and in materials and manufacture, for which Eerdmans books have been known over recent decades. While supervising others who did portions of this work, Klaas himself personally designed most of our books, including the most challenging and design-intensive ones, such as large illustrated reference works, museum catalogs, and specialized monographs that use diagrams, tables, text in non-roman scripts, etc. Expertise in interior design has several components: technological, artistic, and editorial. Klaas excels in all three areas. I recommend him enthusiastically and without reservation.
