Born in France to a Dutch diplomat father and an American mother, Boreel’s parents eventually moved to fashionable Tite Street in Chelsea, where their neighbours included James McNeill Whistler, John Singer Sargent and Glyn Philpot. In 1911 Boreel went to study at the Slade, during which time she also attended Sickert’s evening classes at the Westminster Technical Institute.
