Shown above is a very unusual watch owned by Helen Keller - it was originally made to tell the time by touch alone. Carlene Stephens of the National Museum of American History writes:
This unusual watch, originally made to tell time in the dark, made the perfect present for Helen Keller. Deaf and blind from the age of nineteen months, Keller (1880-1968) grew up to become an accomplished writer and renowned champion for human rights.
In 1892, when she was twelve, Keller met John Hitz, the superintendent of Alexander Graham Bell’s Washington, D.C. establishment for the deaf, the Volta Bureau. Hitz, a retired diplomat, was the proud owner of a Swiss-made “touch watch.” This uncommon watch has a case studded around the edge with pins that correspond to the hours on the watch dial. A revolving hand stops at a point between the pins that corresponds to the hour and approximate minute. With the hand and pins as locators, it was possible to feel the approximate time in the dark or, in the case of a diplomat like Hitz, discreetly. Hitz presented the watch to Keller, who prized it and used it her entire life.
