Harry Cooper is Associate Curator of Modern Art at the Fogg Museum and a Mondrian scholar. Ron Spronk is Associate Research Curator at the Straus Center for Conservation at the Fogg Art Museum with a specialty in early Netherlandish paintings and their technical examination. Working in close collaboration, Cooper and Spronk have studied Piet Mondrian's "transatlantic paintings," works that he painted in Europe and England and reworked, in many cases extensively, after coming to the United States in 1940, shortly after a bomb fell near his apartment in Hampstead.
