When Dorothy was 12, her grandmother suffered a hip fracture. As she recuperated, the doctor warned her not to put too much weight on her hip. This gave Dorothy an idea. She invented the Safe Stepper, a shoe insole which sets off an alarm if more than a prescribed amount of weight is placed on it. After graduation, Dorothy plans to attend Harvard where her biggest problem will be whether to major in biomedical engineering, TV journalism, law, or linguistics.
