Blackwell continued training in London and Paris hospitals, where she studied midwifery and emphasized preventative care, calling out male doctors for not washing their hands in between patients. In 1851, after losing sight in one eye, she returned to New York City, where she had few opportunities due to discrimination against female physicians. In 1857, along with her sister and colleague, Elizabeth Blackwell opened the New York Infirmary for Women and Children, which provided training for women physicians. A decade later, in 1868, Blackwell opened the Woman’s Medical College in New York. This was done in collaboration with Florence Nightingale, another pioneering woman in healthcare! (source).
