What Every Mother Should Know was published in 1914 in New York City, New York, as a compilation of newspaper articles written by Margaret Sanger in 1911. The series of articles informed parents about how to teach their children about reproduction and it appeared in the newspaper New York Call. In 1911, the newspaper series was published as a book, with several subsequent editions appearing later. In What Every Mother Should Know, Sanger emphasizes starting education on reproduction early and honestly answering children’s questions. The book acted as a resource for parents and urged readers to be less fearful of approaching the topic with their children. What Every Mother Should Know provided information to the public about sex education and reproductive health, which was scarce during the early twentieth century.

In the early twentieth century, birth control advocate Margaret Sanger published eight issues of a feminist magazine called The Woman Rebel. During this time, discussion of sex education, birth control, and abortion were illegal. The magazine featured literary pieces on topics like women’s rights, love and marriage, women in the workplace, reproductive and sexual education, and contraception. The Woman Rebel was one of the first magazines that discussed issues that working class American women faced. Through the magazine, Sanger sought to convince female readers to reject their oppression and become what she called women rebels. The Woman Rebel generated attention and controversy around the birth control and feminist movements in the United States during the twentieth century, advancing those movements and creating a community of women with the common intent to rebel against apparent injustice.

On 16 October 1916, Margaret Sanger opened one of the first birth control clinics in the United States in Brooklyn, New York, which some have called the Brownsville Clinic. Located at 46 Amboy Street, the clinic was a place where Sanger and her staff verbally communicated with women seeking information about birth control. During the early 1900s, both birth control and abortion were illegal in the US, and publication or circulation of information on both topics was deemed obscene and illegal by the federal Comstock Act. However, women still sought means to control unwanted pregnancies and visited the clinic to learn about birth control. The clinic was open for only ten days. It shut down after being found guilty of violation of the Comstock Act. The Brownsville Clinic represented a step toward the eventual founding of Planned Parenthood Federation of America, which Sanger led. Despite being short-lived, America’s first birth control clinic provided educational resources to women in New York and raised awareness of the birth control movement in the US through media exposure.
