(b Lüneburg, 30 July 1884; d Munich, 28 Apr. 1969). German art historian. He spent much of his career working in German museums (notably the Kaiser Friedrich Museum in Berlin and Gemäldegalerie in Dresden, of which he was director, 1942–54) and he also taught in England and the USA. His publications were mainly on 16th- and 17th-century art, and he played an important role in the revival of interest in Italian Baroque painting, particularly with his book Die Malerei des Barock in Rom (Baroque Painting in Rome, 1924), which has been described by Rudolf Wittkower as ‘the basic study without which no work in the field can be undertaken’. He was a sensitive connoisseur, as he showed with articles on Veit Stoss (1908), in which he was the first to attribute to him the celebrated St Roch in Florence, and Georges de La Tour (1915), in which he began the rediscovery of this artist.
