Elizabeth Cady Stanton (1815–1902) was one of the most influential women in first wave feminism. An American social activist, she was instrumental in orchestrating the Seneca Falls Convention, the first women's rights convention, which was held in Seneca Falls, New York. Not only was the suffragist movement important to Stanton, she also was involved in women's parental and custody rights, divorce laws, birth control, employment and financial rights, among other issues. Her partner in this movement was the equally influential Susan B. Anthony. Together, they fought for a linguistic shift in the Fourteenth and Fifteenth Amendments to include "female". Additionally, in 1890 she founded the National American Woman Suffrage Association and presided as president until 1892. She produced many speeches, resolutions, letters, calls, and petitions that fed the first wave and kept the spirit alive. Furthermore, by gathering a large number of signatures, she aided the passage of the Married Women's Property Act of 1848 which considered women legally independent of their husbands and granted them property of their own. Together these women formed what was known as the NWSA (National Women Suffrage Association), which focused on working legislatures and the courts to gain suffrage.
