Josephine Myrtle Corbin (May 12, 1868 in Lincoln County, Tennessee– May 6, 1928 in Cleburne, Texas) was born a dipygus (a very rare condition). This referred to the fact that she had two separate pelvises side by side from the waist down, as a result of her body axis splitting as it developed. Each of her smaller inner legs was paired with one of her outer legs. She was said to be able to move her inner legs, but they were too weak for walking. The tiny body of her twin was only fully developed from the waist down and even then it was malformed – tiny and possessing only three toes on each foot. Myrtle was able to control the limbs of her sister but was unable to use them for walking and she herself had a difficult time getting around as she was born with a clubbed foot. In easy word, the other legs were of her unborn twin sister.
