Blanche Dumas was born on the Caribbean island of Martinique in 1860, to a French father and a biracial mother. She had a third leg attached to her sacrum, and her two primary legs were said to be imperfectly developed. The third leg was without a mobile joint but had a bend in it where the knee would have been. Her pelvis was wider than normal and she had double genitalia as well as a duplicate bowel and bladder. To the right of her middle leg was the stump of another limb; it's unknown at this time whether this stump was naturally occurring or the site of a surgical amputation, but promoters sought to maximize its appeal by adorning it with nipples and advertising it a pair of "well-formed" extra breasts!
