At 59 years old, Clara Barton founded the American Red Cross in 1881, which she ran for 23 years.
In 1854, she was the first woman to be hired as a recording clerk at the U.S. Patent Office in Washington D.C. She was paid the same as her male colleagues, but was transferred as a copyist the following year with a lower salary.
Barton quit her job when the Civil War broke out, making it her mission to bring medical supplies to Union soldiers in need and earning her the nickname the “angel of the battlefield.”

In 1916, Margaret Sanger opened up the first birth control clinic in Brownsville, Brooklyn but was arrested shortly thereafter for distributing birth control information, which was illegal at the time. She spent 30 days in jail, during which time she garnered substantial media attention and support from the public.
In 1929, Sanger formed the National Committee on Federal Legislation for Birth Control to lobby Congress for legislation permitting doctors to prescribe birth control. Her efforts would eventually lead to widespread use of contraceptives in the United States.
