Sojourner Truth was the self-given name, from 1843, of Isabella Baumfree, an African-American abolitionist and women's rights activist. Truth was born into slavery in Swartekill, New York. Her best-known speech, Ain't I a Woman?, was delivered in 1851 at the Ohio Women's Rights Convention in Akron, Ohio.
On June 1, 1843, Truth changed her name to Sojourner Truth and told her friends, "The Spirit calls me, and I must go." She became a Methodist, and left to make her way traveling and preaching about abolition. In 1844, she joined the Northampton Association of Education and Industry in Northampton, Massachusetts. Founded by abolitionists, the organization supported women's rights and religious tolerance as well as pacifism. There were 210 members and they lived on 500 acres (2 km²), raising livestock, running a sawmill, a gristmill, and a silk factory. While there, Truth met William Lloyd Garrison, Frederick Douglass, and David Ruggles. In 1846, the group disbanded, unable to support itself. In 1847, she went to work as a housekeeper for George Benson, the brother-in-law of William Lloyd Garrison. In 1849, she visited John Dumont before he moved west.
Truth started dictating her memoirs to her friend Olive Gilbert, and in 1850 William Lloyd Garrison privately published her book, The Narrative of Sojourner Truth: A Northern Slave. That same year, she purchased a home in Northampton for $300, and spoke at the first National Women's Rights Convention in Worcester, Massachusetts.
