Mary Dennett

Mary Coffin Ware Dennett (April 4, 1872 – July 25, 1947) was an American women's rights activist, pacifist, homeopathic advocate, and pioneer in the areas of birth control, sex education, and women's suffrage. She co-founded the National Birth Control League in 1915 together with Jessie Ashley and Clara Gruening Stillman. She founded the Voluntary Parenthood League, served in the National American Women's Suffrage Association, co-founded the Twilight Sleep Association, and wrote a famous pamphlet on sex education and birth control. A famous legal case against her eventually became the catalyst for overturning the Comstock laws. Provided by Wikipedia
