On March 1, 1864, Rebecca Lee Crumpler becomes the first African American woman to earn a medical degree. For much of her career she practiced community medicine in Boston, but in the aftermath of the Civil War she traveled south to treat thousands of formerly enslaved refugees. Crumpler wrote one of the first medical manuals by an African American doctor in the United States—and by a woman.

Rebecca Lee Crumpler was born Rebecca Davis in 1831 in Christiana, Delaware. She spent her formative years living in Philadelphia with her aunt, a respected community healer. After moving to Massachusetts and practicing nursing for several years, Rebecca Davis, now Rebecca Lee, applied to the New England Female Medical College in Boston, the first women’s medical school in the nation. The college admitted her in 1860, based on her nursing experience and strong recommendations from doctors familiar with her work. She graduated in 1864 as a “Doctress of Medicine.”
