Martha Ballard somehow managed to deliver 797 babies in Hallowell (now Augusta), Maine, between 1785 and 1812, when she kept her now-famous diary. She reckoned she performed a total of 981 deliveries in her lifetime, since she only started keeping her diary when she was 50 years old.
Martha Ballard was a midwife and a healer on the Maine frontier who used home-grown remedies and traveled by horse and canoe to her patients. Nonetheless, she was a more methodical and progressive practitioner than most country doctors in at least one respect, argues Laurel Thatcher Ulrich, who wrote A Midwife's Tale from Ballard's diary. Martha Ballard kept medical records -- in her diary -- which most country doctors didn't do. Her diary is practically the only medical record that exists for Hallowell in the 18th century save for a one-page letter.
In other ways, Ulrich notes, Martha Ballard's habits weren't all that different from those of the best doctors of the age. She attended autopsies, meticulously recorded medical and obstetrical details, paid attention to vital records and was generally committed to facts.
