Mary Hobart was a medical doctor in Boston, Massachusetts in the late 19th and early 20th century. She specialized in obstetrics where she was known for her independence and resources. There are many times in her life where her career correlated with that of her great-great-grandmother's, Martha Ballard. Nevertheless, Mary Hobart sought out the medical profession by her own ambition as an early entrant. Her service was due in part to caring for the poor in hospitals. Furthermore, Hobart chose to be single for her entire life since she could independently support herself. She practiced for 30 years in Boston before she decided to retire in Needham Heights, Massachusetts.
By the time Hobart graduated from the Women's Medical College, her cousin Lucy Lambard Fessenden gathered her great-great-grandmother's historical diary for her great aunts to give to Mary. Though Mary is known to be a pioneer in medicine, her great-great-grandmother, Martha Ballard, is a late 18th-century housewife whose diary is the main source for the book, A Midwife’s Tale. Since Hobart was one of few to graduate from medical school in her family, it was only fitting to have a diary of medical importance passed down to her. Hobart was thirty-three when she received “a hopeless pile of loose unconsecutive pages”. Her great aunts, Sarah Lambard and Hannah Lambard Walcott, decided it was best for Hobart to take care of the diary. She decided to donate the diary to the Maine State Library in 1930. In exchange of the donation, Hobart expected a transcript copy of the diary. She never received a full translation of the work, but Hobart was grateful for the parts she was given.
