The Chicago Women’s Liberation Union, hereafter Union or CWLU, was a feminist union that operated in Chicago, Illinois, from 1969 to 1977 and was the first and largest union, at the time of its operation, focused on women’s issues. The Union organized women with the self-proclaimed collective goal of achieving liberation from sexism and inequality. Within the larger CWLU, smaller groups and chapters formed to address issues such as abortion, rape, child care, and reproductive health, among others. During CWLU’s eight years of operation, the activists circulated petitions, held demonstrations, and visited high schools to raise public awareness of women’s issues. The CWLU created educational opportunities for women in response to apparent sexism in the US and connected them to social groups to further the women’s liberation movement and women’s reproductive health awareness in the United States.

Norman Haire was a physician who advocated for eugenics, which is the betterment of human population by promoting positive traits, and birth control rights in the twentieth century in both Australia and the UK. In the UK, Haire joined the Malthusian League, a contraception advocacy organization, and helped the League open the first physician-supervised birth control clinic, called Walworth Women’s Welfare Centre in London, England. Throughout his life, Haire worked closely with other well-known contraception and women’s rights advocates in the early 1900s including Margaret Sanger, Marie Stopes, and Havelock Ellis. Haire was also known for his work on sexual rejuvenation, an early twentieth century theory that the male sexual appetite could be restored through vasectomies and hormonal injections. Haire advocated for birth control rights through his practice, conference lectures, radio debates, and published work. His activism in the fields of eugenics, contraception, and sexual reform promoted the emergence of more liberal attitudes towards sex and controlled reproduction and in the twentieth century.

Where Are My Children? is an anti-abortion silent film released in the United States on 16 April 1916. The film was directed by Lois Weber and Phillips Smalley and produced by Universal Film Manufacturing Company/Lois Weber Productions in Universal City, California. In the film, Weber tells a story of an attorney who wants to have children and raise a family, but his wife chooses to abort her pregnancies, fearing that having children will ruin her social activities. In the early 1900s, information about contraception was not freely available or legal to obtain. Physicians were allowed to distribute contraceptives only if the woman would be put in a life-threatening circumstance were she to get pregnant. In the film, Weber encourages contraceptives as a means of family planning, but advocates against abortions. Where Are My Children? is one of the first films to discuss birth control and family planning, and it is among the first to push against motion picture censorship of contraception and family planning in cinema.

In 1832, Charles Knowlton published The Fruits of Philosophy, a pamphlet advocating for controlling reproduction and detailing methods for preventing pregnancy. Originally published anonymously in Massachusetts, The Fruits of Philosophy was an illegal book because United States law prohibited the publishing of immoral and obscene material, which included information about contraception. In The Fruits of Philosophy, Knowlton detailed recipes for contraceptives and advocated for controlling reproduction. In 1877 in Europe, social activists Charles Bradlaugh and Annie Besant republished the pamphlet in London, England. At that time, many governments, including the United Kingdom, still considered the book illegal material due to its discussion of contraception. The Fruits of Philosophy was one of the first publications detailing contraceptive methods for controlling reproduction and activists used it in some of the first attempts at repealing obscenity laws in the United States and Great Britain. Through their efforts, Knowlton and those who later republished the pamphlet increased knowledge of reproduction and awareness of methods of contraception. By challenging anti-obscenity laws, the author and activists also helped with the eventual weakening and dissolution of such law.

Charles Knowlton was a physician and author who advocated for increased access to information about reproduction in the nineteenth century in the US. Throughout his early medical education, Knowlton was particularly interested in anatomy and on several instances robbed graves for bodies to dissect. In 1832, Knowlton authored The Fruits of Philosophy, a pamphlet that contained detailed descriptions of the reproductive organs and information on conception and methods to control reproduction. Knowlton circulated his work among his patients until it was republished in Boston, Massachusetts, in 1832. For publishing a book on sex and methods of birth control, Knowlton was convicted of breaking obscenity laws, which prevented the transmission of obscene materials. After his death, social activists Charles Bradlaugh and Annie Besant republished his work in London, England. Knowlton’s writing about sex and birth control allowed individuals to understand and take control of their reproduction and initiated a public discussion about obscenity laws.

The Dalkon Shield was an intrauterine contraceptive device (IUD) that women used in the early 1970s and 1980s. Produced by the A.H. Robins Company in the US, the Dalkon Shield was a contraceptive device placed directly into a woman’s uterus that was supposed to prevent the development of a fetus in the uterus. In the 1980s, researchers uncovered an array of severe birth defects and injuries caused by the Dalkon shield, including pelvic infection, infertility, and death of the user. Eventually the A.H. Robins Company took the shield off the market, and the US Food and Drug Administration banned the device. Some users of the Dalkon shield sued the producers of the device, winning millions of dollars in compensation and punitive damages. After the dangers of the Dalkon Shield became public through those lawsuits, the popularity of intrauterine devices decreased significantly in the US.

Emma Goldman was a traveling public speaker and writer known for her anarchist political views as well as her opinions on contraception and birth limiting in the late nineteenth century in the United States. Goldman identified as an anarchist, which she explained as being part of an ideology in which people use violence to provoke or demand social and political change. Goldman was involved in many anarchist social groups and published the anarchist magazine Mother Earth. She spent the majority of her life traveling the US and Europe giving lectures and presentations to spread her views on the political events during her lifetime. Goldman also worked to spread awareness about birth control and contraceptive options in response to the lack of birth control options she witnessed while working as a nurse. By advocating for birth control in her travels, Goldman brought international attention to topics like birth control and women’s rights during the late nineteenth and early twentieth centuries.

Barbara Seaman was a writer, investigator, and advocate for female healthcare rights during the twentieth century in the United States. Seaman’s work addressed the gendered prejudice she observed in the US healthcare system and argued that women of the 1960s lacked the proper tools to make informed decisions about pregnancy care, breastfeeding, childbirth, and contraception. Seaman wrote the book The Doctor’s Case Against the Pill in 1969 to expose the dangers in prescribing and consuming high doses of estrogen in the form of birth control. Seaman’s objective was to expose what she described as pharmaceutical companies’ drive for profit over safety. Her reporting helped provide a voice to many women who lacked proper health information and helped improve the standard of healthcare that women received in the US. Through her publications and activism, Seaman brought women’s healthcare to the public’s attention and contributed to the feminist and women’s healthcare movements of the twentieth century.

In 2013, Lois Uttley, Sheila Reynertson, Larraine Kenny, and Louise Melling published “Miscarriage of Medicine: The Growth of Catholic Hospitals and the Threat to Reproductive Health Care,” in which they analyzed the growth of Catholic hospitals in the United States from 2001 to 2011 and the impact those hospitals had on reproductive health care. In the US, Catholic hospitals are required to abide by the US Catholic Church's Ethical Guidelines for Health Care Providers, also called the Directives. The authors of the article argue that the Directives threaten reproductive health because of their limitations on contraception, sterilization, some infertility treatments, and abortion. The report demonstrated an increase in Catholic hospitals and an associated impact on reproductive health care, which formed the basis for lawsuits the American Civil Liberties Union brought against various Catholic hospitals and health care networks during the early 2000s.
