Margaret Higgins Sanger (September 14, 1879 - September 6, 1966) was an American birth control activist, sex educator, and nurse. Sanger popularized the term birth control, opened the first birth control clinic in the United States, and established organizations that evolved into the Planned Parenthood Federation of America. Sanger's efforts contributed to several judicial cases that helped legalize contraception in the United States. Sanger is a frequent target of criticism by opponents of birth control and has also been criticized for supporting eugenics, but remains an iconic figure in the American reproductive rights movement. In 1916, Sanger opened the first birth control clinic in the United States, which led to her arrest for distributing information on contraception. Her subsequent trial and appeal generated controversy. Sanger felt that in order for women to have a more equal footing in society and to lead healthier lives, they needed to be able to determine when to bear children. She also wanted to prevent unsafe abortions, so-called back-alley abortions, which were common at the time because abortions were usually illegal. She believed that while abortion was sometimes justified it should generally be avoided, and she considered contraception the only practical way to avoid the use of abortions. In 1921, Sanger founded the American Birth Control League, which later became the Planned Parenthood Federation of America. In New York City, she organized the first birth control clinic staffed by all-female doctors, as well as a clinic in Harlem with an entirely African-American staff. In 1929, she formed the National Committee on Federal Legislation for Birth Control, which served as the focal point of her lobbying efforts to legalize contraception in the United States. From 1952 to 1959, Sanger served as president of the International Planned Parenthood Federation. She died in 1966, and is widely regarded as a founder of the modern birth control movement.
