(1883?-1966), social reformer. A leader of the birth control movement during the early 1900s, Sanger founded the American Birth Control League in 1921 and became the first president of the International Planned Parenthood Federation in 1953. Appalled by her observations while working as a nurse with the poor, Sanger opened the first birth control clinic in the United States in Brooklyn, New York, in 1916, for which she was arrested and sent to prison. She organized the first World Population Conference in Geneva (1927) and helped obtain passage of laws allowing doctors to give birth control advice.
