Mary Edwards Walker (1832 – 1919) was an American feminist, abolitionist, and surgeon who became the only woman, and one of only eight civilians, to receive the Medal of Honor.
She worked as a teacher to pay her way through Geneva Medical College (now Hobart College), where she graduated as a medical doctor in 1855, the only woman in her class. She married fellow medical school student Albert Miller set up a joint practice in Rome, New York. It failed to take off, largely because female physicians were generally not trusted or respected at that time. Walker briefly attended Bowen Collegiate Institute (later named Lenox College) in 1860, until she was suspended after refusing to quit the all-male school debating society.
