an American entrepreneur who became the second female pharmacist in the United States. Marshall worked as an apprentice in the family pharmacy from 1805. She inherited her grandfather's pharmacy, Marshall Drug Store, in 1804 and managed the business until 1825. Marshall is regarded by some as being the first female pharmacist in the United States, though Elizabeth Gooking Greenleaf was the first in 1727. Marshall ran the pharmacy for two decades.
