Mary Corinna Putnam Jacobi (1842-1906) was an American physician, writer, and suffragist. She crusaded for the integration of clinical and laboratory studies and for scientific research on women's health rather than anectdotal evidence. Her work with reformers and suffragists made her a leading spokesman for women's health during the Progressive Era. She graduated from the New York College of Pharmacy in 1863 and earned her M.D. from the Female (later Women's) Medical College of Pennsylvania in 1864. After much negotiation, she was admitted as the first woman student to the ?cole de M矇decine of the University of Paris. She graduated in July 1871, the second woman to get a degree there, and received second prize for her thesis. After returning to the United States in the fall of 1871, she established a medical practice in New York City, became the second woman member of the Medical Society of the County of New York, was admitted to the American Medical Association, and became a professor in the new Woman's Medical College of the New York Infirmary. In 1873, Mary Putnam married Dr. Abraham Jacobi who is often referred to as the "father of American pediatrics."
