"What every mother should tell, or how six little children were taught the truth" by Margaret Sanger. Published in 1927. Margaret Sanger (1879-1966) 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 was also a writer. She used this method to help promote her way of thinking. She was prosecuted for her book Family Limitation under the Comstock Act in 1914. She was afraid of what would happen, so she fled to Britain until she knew it was safe to return to the US. Sanger's efforts contributed to several judicial cases that helped legalize contraception in the United States.
