in Education; or, A Fair Chance for the Girls (1875), a book claiming that any physical or mental exertion during menstruation could lead to women becoming infertile. Jacobi did not believe this was the case, and to test the idea she collected extensive physiological data on women throughout their menstrual cycle, including muscle strength tests before and after menstruation. She concluded that "there is nothing in the nature of menstruation to imply the necessity, or even desirability, of rest." Jacobi wrote over 120 medical articles and nine books, although she stopped writing fiction in 1871. In 1891 she contributed a paper on the history of women physicians in the United States to the volume Women's Work in America that included a bibliography of writings by American female physicians mentioning over forty of her own works. In 1894, she wrote Common Sense Applied to Women's Suffrage which was later reprinted and used to support the women's suffrage movement in the United States. Also in 1894, after the defeat of the women's suffrage amendment to the New York State Constitution, Jacobi was one of six prominent suffragists who founded the League for Political Education. While Elizabeth Blackwell (1821–1910) viewed medicine as a means for social and moral reform, the younger Jacobi focused on curing disease. Blackwell believed that women would succeed in medicine because of their humane feminine values, but Jacobi thought women's contribution to all medical specialties should be considered equivalent to men's. Death and legacy When diagnosed with a brain tumor, she meticulously documented her symptoms and published a paper on the subject titled Descriptions of the Early Symptoms of the Meningeal Tumor Compressing the Cerebellum. From Which the Writer Died. Written by Herself. She died in New York City on June 10, 1906. Jacobi is interred at Green-Wood Cemetery in Brooklyn, New York.
