Elizabeth Hobbs Keckley (February 1818 – May 1907) was an African-American seamstress, activist, and writer who lived in Washington, D.C. She was the personal dressmaker and confidante of Mary Todd Lincoln. She wrote an autobiography. Elizabeth also started the Contraband Relief Association in August 1862, later called the Ladies’ Freedmen and Soldiers’ Relief Association, to help formerly enslaved people and the families of Black soldiers during the Civil War.

She was born enslaved to Armistead Burwell who had also fathered her. Keckley would later be bound to Armistead's daughter Anne Burwell Garland, the wife of Hugh A. Garland. She became a nursemaid to an infant when she was four years old. She received brutal treatment—including being raped and whipped to the point of bleeding welts—from Burwell's family members and a family friend. When she became a seamstress, the Garland family found that it was financially advantageous to have her make clothes for others. The money that she made helped to support the 17 members of the Garland family.

In November 1855, she purchased her and her son's freedom in St. Louis, Missouri. Keckley moved to Washington, D.C., in 1860. She established a dressmaking business that grew to include a staff of 20 seamstresses. Her clients were the wives of elite politicians, including Varina Davis, the wife of Jefferson Davis, and Mary Anna Custis Lee, the wife of Robert E. Lee.

After the American Civil War, Keckley wrote and published an autobiography, Behind the Scenes: Or, Thirty Years a Slave and Four Years in the White House, in 1868. It was both a slave narrative and a portrait of the first family, especially Mary Todd Lincoln, and it was controversial because of information it disclosed about the Lincolns' private lives.

Elizabeth Keckley (or Keckly) was born into slavery in February 1818, in Dinwiddie County Court House, Dinwiddie, Virginia, just south of Petersburg. She was the only child of her mother Agnes, a light-skinned Black woman whose white ancestors were members of the planter class. Her mother, nicknamed "Aggy", was a "house slave" who had learned to read and write even though it was illegal for enslaved people. She made clothes for 82 people: 12 members of the Burwell family and the 70 people they enslaved. Keckley learned that her father was Armistead Burwell from her mother just before she died. He permitted Agnes to marry George Pleasant Hobbs, a literate enslaved man who lived and worked at a neighbor's house during Keckley's early childhood. When Hobbs' owner moved far away, Hobbs was separated from Agnes. Although they were never reunited, Agnes and George corresponded for many years. As an adult, Elizabeth Keckley noted "the most precious mementos of my existence are the faded old letters that he wrote, full of love, and always hoping that the future would bring brighter days."

Keckley was enslaved by Burwell, who served as a colonel in the War of 1812, and his wife Mary. She lived in the Burwell house with her mother and began working when she was 4 years old. The Burwells had four children under the age of 10, and Keckley was assigned to be the nursemaid for their infant Elizabeth Margaret. Keckley was harshly punished if she failed to care properly for the baby. One day she accidentally tipped the cradle over too far, causing the infant to roll onto the floor, and Mary Burwell beat her severely. As she grew up, Keckley helped her mother make clothes.

At the age of 14, in 1832, Keckley was sent "on generous loan" to live with and serve the eldest Burwell son Robert in Chesterfield County, Virginia, near Petersburg, when he married Margaret Anna Robertson. Robert was Elizabeth's half-brother. She was their only servant. The new bride expressed contempt for Keckley, perhaps because her obvious white ancestry made the older woman uneasy; perhaps Keckley resembled Robert. Margaret made home life unpleasant for the young Keckley for the next four years. The family moved to Hillsborough, North Carolina, where Robert was a minister and operated the Burwell School for girls from his house from 1837 to 1857. Keckley stated that Margaret seemed "desirous to wreak vengeance" upon her.

Margaret enlisted neighbor William J. Bingham to help subdue Elizabeth's "stubborn pride". When Keckley was 18, Bingham called her to his quarters and ordered her to undress so that he could beat her. Keckley refused, saying she was fully grown, and "you shall not whip me unless you prove the stronger. Nobody has a right to whip me but my own master, and nobody shall do so if I can prevent it." Bingham bound her hands and beat her, then sent her back to her master with bleeding welts on her back. The next week, Bingham flogged her again until he was exhausted. Again Elizabeth was sent back to her master with bleeding welts upon her back. A week later, Bingham flogged her again until he was exhausted, while she suppressed her tears and cries. The next week, after yet another attempt to "break her", Bingham had a change of heart, "burst[ing] into tears, and declar[ing] that it would be a sin" to beat her anymore. He asked for her forgiveness and said that he would not beat her again. Keckley claims that he kept his word.
