"[Margaret Sanger] said that when she started out in 1912, one of the first things she thought of was a new method for women to use. She after all was a nurse. She was an obstetrical nurse. She knew about birth control. She knew what methods were out there, and she knew they were lousy. She knew they worked sporadically. She knew it took the cooperation of the male and the female, the man and the woman, to make the method work. This was not always satisfactory, and she wanted to apply science and medicine to her feminist mission of giving women control of childbearing, so from the very early days in 1912, she dreamt of a pill. She knew the science wasn't there yet, which is why it took over four decades for this to happen."
