Margaret Sanger (September 14, 1879 – September 6, 1966) was an American birth control activist, sex educator, and nurse. She opened the first birth control clinic in the United States, founded Planned Parenthood, and was instrumental in the development of the first birth control pill. She was an important first-wave feminist and believed that women should be able to decide if and when to have children. Sanger campaigned for the legalization of contraceptives by giving speeches, writing books, and breaking laws – leading to eight arrests. She endorsed both the Malthusianism and eugenics movements, believing that they would generate support for birth control. She established a network of dozens of birth control clinics, which provided services to hundreds of thousands of patients. She discouraged abortion, and her clinics never offered abortion services during her lifetime. Her activism led to the Griswold v. Connecticut decision, which legalized contraception.
