In contrast to Bernhardt's outgoing personality, which thrived on publicity, Duse was introverted and private, rarely giving interviews. She found public appearances to be a distraction, and once remarked to a journalist that away from the stage, "I do not exist". Bernhardt and Duse were unspoken rivals for many years. Comparisons of Duse to Bernhardt with regard to their acting talent were common, with warring factions arguing over their relative merits. Those who thought Duse the greater artist included George Bernard Shaw, who saw both actresses in London within the span of a few days, in the same play. Shaw gave his nod to Duse and defended his choice in an adamant oratory quoted by biographer Frances Winwar. Ellen Terry, a famous British actress of the era who knew both well, observed "How futile it is to make comparisons! Better far to thank heaven for both these women."
