Take a peek at this amazing photo gallery of the woman with four legs. This is Josephene Myrtle Corbin, born in Tennessee in 1869, passed away in 1928. She was born as a dipygus, which means she had two completely separate pelvises next to each other, below her waist.
Because of this, her body split as it began to develop. The smaller inner legs were each paired with one of the outer legs. She told people that she could move the smaller legs, but they were not strong enough to walk on.
If she was around today, she would no doubt be making millions producing entertainment videos for people to gawk at. However, back in her day, her only option was to become a sideshow freak, which is what she did.
