The Human Marvels has a post about Dick Hilburn, the so-called "Quarter-Man" because he was born with just one arm and physically little else:
Dick Hilburn was born with a single arm and physically little else. He possessed no left arm and no legs, only a vestigial two-toed foot protruded from his left hip. Yet, despite what would normally be considered a crippling handicap, Dick Hilburn possessed an unconquerable spirit and indomitable work ethic which allowed him to not only surpass expectations but to also exceed the ambitions of many able-bodied men.
Dick Hilburn conquered his mobility limitations with little more than a rolling board. He used his arm to propel and steer his body and in the process developed great physical strength. That strength allowed him to hoist his body wherever he willed it with relative ease.
