A brief read about Anne Sullivan Macy (1866-1936), tutor and lifelong companion of Helen Keller, is on Wikipedia. The most interesting statement: “As soon as she arrived, she argued with Helen’s parents about the Civil War and over the fact that they had owned slaves. However, she also quickly connected with Helen. It was the beginning of a 49-year relationship: Sullivan evolved from teacher to governess and finally to companion and friend.” Anne died at age 70 with Helen holding her hand.
