Castille Art Research is a professional partnership between Delphine Huisinga and Ross Finocchio forged under the guidance of British biographer and art critic Sir John Richardson. Throughout the 1950s, Richardson lived at the Château de Castille in southern France, where he became an intimate acquaintance of Pablo Picasso. Countless hours spent with the artist and his inner circle of family and friends later became the basis for Richardson’s authoritative multivolume biography Picasso, internationally recognized as an art-historical and literary landmark.

In 2013–14, Richardson chose Delphine and Ross to collaborate with him on the fourth and final volume of that biography: A Life of Picasso: The Minotaur Years, 1933–1943. Their close relationship with the author and deep knowledge of his scholarship and methodology prepared them to bring the much-anticipated book to completion after Richardson’s death in 2019. 

They now offer that knowledge and expertise, backed by over two decades of curatorial experience at world-class museums, to clients of Castille Art Research, a New York-and-Paris-based consulting firm specializing in historical, archival, and provenance research as well as writing, curating, cataloguing, translation, collections management, and strategic planning for institutional and private collectors.
