Margaret Sanger
Margaret Sanger (September 14, 1883 – September 6, 1966) was a famous birth control rights activist. She established the American Birth Control League in 1921. This eventually became what we now know as Planned Parenthood in 1946. She helped finance biologist Gregory Pincus's creation of the birth control pill. Mrs. Sanger has been credited as the first person to use the term “birth control”. Birth control is used to describe contraception, or ways of preventing unwanted pregnancy. She paved the way for contraception to become a widely accepted social practice at a time when spreading information about birth control was prohibited by law.
