Mary Putnam Jacobi (August 31, 1842 – June 10, 1906) was a groundbreaking American physician, educator, and researcher who shattered gender barriers in medicine during the 19th century. As one of the first women to attend the prestigious École de Médecine in Paris, Jacobi earned her medical degree in 1869, proving women’s capabilities in a male-dominated field.
Throughout her career, Mary Putnam Jacobi was a fierce advocate for women’s medical education and scientific rigor. She conducted pioneering research on women’s health and physiology, famously debunking myths that women were biologically inferior or unfit for intellectual work. Her influential essay, The Question of Rest for Women during Menstruation (1876), challenged outdated medical prejudices and helped transform societal attitudes.
Mary Putnam Jacobi also played a vital role in advancing medical education in the United States, teaching at the Woman’s Medical College of Pennsylvania and contributing to key medical journals. Her legacy lives on as a trailblazer who expanded opportunities for women in medicine and championed evidence-based science.
