A few weeks after her thirteenth birthday, Anthony officially became a member of the Society of Friends. One of their main values is “the equality of all people before God” (Lutz 11). Quakers not only encouraged but demanded education for both boys and girls. As soon as Anthony was old enough, she worked and taught in the “home school” during the summer, educating younger children. Further expanding her education in 1837, Anthony's father sent her to the Friends’ Seminary near Philadelphia, where she studied a variety of subjects: arithmetic, algebra, literature, chemistry, philosophy, physiology, astronomy, and bookkeeping.
