Myrtle Corbin, known as the Four-Legged Girl from Texas, was a dipygus. She was born with a severe congenital deformity of conjoined twining that caused her to have two separate pelvises and a smaller set of inner legs that she was able to move. When she was just a month old, her father began showing her to curious neighbors for a dime. Eventually she attracted the attention of P.T. Barnum, and began performing when she was 13. She later performed with the Ringling Bros. and Coney Island.
