In 1851, Anthony was introduced to Elizabeth Cady Stanton, who had been one of the organizers of the Seneca Falls Convention and had introduced the controversial resolution in support of women's suffrage. Anthony and Stanton soon became close friends and co-workers, forming a relationship that was pivotal for them and for the women's movement as a whole. After the Stantons moved from Seneca Falls to New York City in 1861, a room was set aside for Anthony in every house they lived in. One of Stanton's biographers estimated that over her lifetime, Stanton spent more time with Anthony than with any other adult, including her own husband.
The two women had complementary skills. Anthony excelled at organizing, while Stanton had an aptitude for intellectual matters and writing. Anthony was dissatisfied with her own writing ability and wrote relatively little for publication. When historians illustrate her thoughts with direct quotes, they usually take them from her speeches, letters and diary entries.
Because Stanton was homebound with seven children while Anthony was unmarried and free to travel, Anthony assisted Stanton by supervising her children while Stanton wrote. One of Anthony's biographers said, "Susan became one of the family and was almost another mother to Mrs. Stanton's children." A biography of Stanton says that during the early years of their relationship, "Stanton provided the ideas, rhetoric, and strategy; Anthony delivered the speeches, circulated petitions, and rented the halls. Anthony prodded and Stanton produced." Stanton's husband said, "Susan stirred the puddings, Elizabeth stirred up Susan, and then Susan stirs up the world!" Stanton herself said, "I forged the thunderbolts, she fired them." By 1854, Anthony and Stanton "had perfected a collaboration that made the New York State movement the most sophisticated in the country", according to Ann D. Gordon, a professor of women's history.
