Sara Josephine Baker Sara Josephine Baker (November 15, 1873 – February 22, 1945) was an American physician notable for making contributions to public health, especially in the immigrant communities of New York City. Her fight against the damage that widespread urban poverty and ignorance caused to children, especially newborns, is perhaps her most lasting legacy. In 1917, she noted that babies born in the United States faced a higher mortality rate than soldiers fighting in World War I, drawing a great deal of attention to her cause. She also is known for (twice) tracking down Mary Mallon, the infamous index case known as Typhoid Mary.
Birth control movement in the United States The birth control movement in the United States was a social reform campaign from 1914 to around 1945 that aimed to increase the availability of contraception in the U.S. through education and legalization. The movement began in 1914 when a group of political radicals in New York City, led by Emma Goldman, Mary Dennett, and Margaret Sanger, became concerned about the hardships that childbirth and self-induced abortions brought to low-income women. Sanger, in particular, simultaneously sought to connect birth control to the organized eugenics movement, regularly appealing to the authority of eugenic scientists Karl Pearson, Charles Davenport, and others in her "Birth Control Review" from the early 1920s Such figures sought to prevent population segments they deemed genetically 'undesirable' from reproducing. While seeking legitimacy for the birth control movement partly through the approval of organized eugenics, Sanger and other activists also worked on the political front. Since contraception was considered to be obscene at the time, the activists targeted the Comstock laws, which prohibited distribution of any "obscene, lewd, and/or lascivious" materials through the mail. Hoping to provoke a favorable legal decision, Sanger deliberately broke the law by distributing "The Woman Rebel", a newsletter containing a discussion of contraception. In 1916, Sanger opened the first birth control clinic in the United States, but the clinic was immediately shut down by police, and Sanger was sentenced to 30 days in jail.
