In 1891, after surviving a series of miscarriages, Amanda Mueller was accused of being the Black Womb killer. Her obstetrician was none other than Dr. Milbury, an identity used by Mr. Sinister. Mueller was married to Daniel Summers, who left Amanda with their only son because he couldn't handle the accusations. Amanda headed the Black Womb Project in her later years. In one video she smothered a mutant child for her research.
