His journey into provenance research began in 2013 with research for his book on the German-Dutch Proehl banking family, which was published in 2015. For over two years, he pieced together the fate of the family and its art collection amid the turmoil of World War II—a detective-like investigation of primary sources that has captivated him ever since.
What began as a personal research project alongside his work as a project manager at Hewlett-Packard has become his professional specialty. Since 2019, Achim Bovelett has been conducting intensive research on Nazi-looted art in the holdings of the National Collection of the Netherlands. A particular focus of his work is on German-Dutch connections, the so-called “NRW-Netherlands axis.” —he is currently working on a case involving the systematic looting of porcelain from The Hague to Düsseldorf. The scope of his client work ranges from restitution and compensation proceedings to genealogical investigations and historical background research, as well as cases involving musical instruments.
To actively advance the restitution process, he co-founded the “Claimants for Claimants” foundation (claimants4.org) in early 2025 together with Mr. Marty L. Hamburger, a specialist attorney from Amsterdam, and TV genealogist Klaas Zondervan. The initiative exemplifies his ability to translate theoretical research into practical justice for those affected and to coordinate complex, transnational networks.
His degree in history, which he completed with a Magister Artium, combined with his many years of experience in IT project management at HP, come together in his work to form a rare combination: classical source criticism meets efficient, structured, and modern working methods. He embraced the use of AI in research early on and with great success; compiling subject-specific inventories and working within digital research infrastructures are part of his daily toolkit.
After 12 years in provenance research, Achim Bovelett is thoroughly familiar with a wide variety of schemes, some of which are criminally motivated. His work at the intersection of genealogy, law, and art history allows him to examine trade networks and contexts of misappropriation holistically and across national borders.
