When did the Royal College of Art in London grant Moore a scholarship ?
Moore later became uncomfortable with classically derived ideals ; his later familiarity with primitivism and the influence of sculptors such as Constantin Brâncuși , Jacob Epstein , Henri Gaudier - Brzeska and Frank Dobson led him to the method of direct carving , in which imperfections in the material and marks left by tools became part of the finished sculpture .
