Southern white writers produced the "Anti-Tom" novels in response, purporting to truly describe life under slavery, as well as the more severe cruelties suffered by free labor in the North. Examples include "Aunt Phillis's Cabin" (1852) by Mary Henderson Eastman and "The Sword and the Distaff" (1853) by William Gilmore Simms. The slave narratives were integral to African-American literature. Some 6,000 former slaves from North America and the Caribbean wrote accounts of their lives, with about 150 of these published as separate books or pamphlets. Slave narratives can be broadly categorized into three distinct forms: tales of religious redemption, tales to inspire the abolitionist struggle, and tales of progress. The tales written to inspire the abolitionist struggle are the most famous because they tend to have a strong autobiographical motif. Many of them are now recognized as the most literary of all 19th-century writings by African Americans, with two of the best-known being Frederick Douglass's autobiography and "Incidents in the Life of a Slave Girl" by Harriet Jacobs (1861). Jacobs (1813–1897) was born a slave in Edenton, North Carolina and was the first woman to author a slave narrative in the United States. Although her narrative "Incidents in the Life of a Slave Girl" was written under the pseudonym "Linda Brent", the autobiography can be traced through a series of letters from Jacobs to various friends and advisors, most importantly to Lydia Maria Child, the eventual editor of incidents. The narrative details Jacobs' struggle for freedom, not only for herself but for her two children. Jacobs' narrative occupies an important place in the history of African-American literature as it discloses through her firsthand example the specific injustices that black women suffered under slavery. Harriet Beecher Stowe was asked to write a foreword for Jacob's book, but refused. Frederick Douglass (c. 1818–1895) first came to public attention in the North as an orator for abolition and as the author of a moving slave narrative. He eventually became the most prominent African American of his time and one of the most influential lecturers and authors in American history. Born into slavery in Maryland, Douglass eventually escaped and worked for numerous abolitionist causes. He also edited a number of newspapers. Douglass' best-known work is his autobiography, "Narrative of the Life of Frederick Douglass, an American Slave", which was published in 1845.
