William S. Heckscher
From 1918 to 1921, the family lived in the Netherlands while Heckscher's father served as the Weimar Republic's ambassador to The Hague; there, Heckscher enrolled at the Nederlandsch Lyceum. Heckscher pursued his interests in history and Flemish art by spending his off hours studying at the Dutch Royal Library, the Mauritshuis and the Kröller-Müller Museum, but was dismissed from the Lyceum in 1920 for "lack of scholarly potential". After the family returned to Hamburg, Heckscher attended the city's Kunstgewerbeschule, now the Hochschule für bildende Künste Hamburg, but failed a class in ceramics.
