Art critic and historian of Italian renaissance. Cartwright was the daughter of Richard Aubrey Cartwright and Mary Fremantle (Cartwright) (d. 1885). She was privately schooled. Her earliest exposure to art may have come from her uncle William Cornwallis Cartwright (d.1915), an art collector, who allowed her early access to his library and gallery at Aynhoe, Northamptonshire. She toured France, Austria, and Italy with her family in 1868.
