Dorothea Lynde Dix was born on April 4, 1802, in Hampden, Maine. She was the eldest of three children, and her father, Joseph Dix, was a religious fanatic and distributor of religious tracts who made Dorothea stitch and paste the tracts together, a chore she hated. At age 12, Dix left home to live with her grandmother in Boston, and then an aunt in Worcester, Massachusetts. She began teaching school at age 14. In 1819, she returned to Boston and founded the Dix Mansion, a school for girls, along with a charity school that poor girls could attend for free. She began writing textbooks, with her most famous, Conversations on Common Things, published in 1824.
