England Hospital for Women and Children, Mary decided to further her study of medicine and apply to École de Médecine of the University of Paris. After much negotiation and thanks to the help of the psychiatrist Benjamin Ball, in 1868 she was admitted as the first woman student at École de Médecine, although as a woman she was required to enter lectures through a separate door and sit at the front near the professor. In July 1871 Jacobi graduated with honors and was the second woman to receive a degree from École de Médecine of the University of Paris. Jacobi also received a bronze medal for her thesis. Her studies in Paris coincided with the Franco-Prussian War. In Scribner's Monthly of August 1871, she published an account of the new French political leadership that came to power following the war. After five years of studying in Paris, Jacobi returned to the United States in the fall of 1871. Moving back to New York City, Jacobi established her own private medical practice. Jacobi also participated in research and became a professor in the new Women's Medical College of the New York Infirmary and Mount Sinai Hospital. Jacobi became the second woman member of the Medical Society of the County of New York, was admitted to the American Medical Association. In 1872 she helped to found the Women's Medical Association of New York City, and served as its president from 1874 to 1903. She campaigned consistently for leading medical schools, like Johns Hopkins, to admit women students. Her teaching at the Medical College tended to exceed what her students were prepared for and led her to resign in 1888. Dr. Jacobi was highly revered during her lifetime as the most accomplished woman physician. In 1873, she married Abraham Jacobi, a New York physician and researcher, nowadays often referred to as the "father of American pediatrics." They had three children, two daughters, and one son. Mary and Abraham's first daughter died at birth and their only son died at the age of seven. Abraham and Mary had only one child who survived to adulthood, their daughter Marjorie Jacobi McAneny. Jacobi educated her daughter herself according to her own educational theories. She received Harvard University's Boylston Prize in 1876 for an original essay, The Question of Rest for Women during Menstruation. Jacobi's paper was a response to Dr. Edward H. Clarke's earlier publication, Sex
