Frederick Douglass (born Frederick Augustus Washington Bailey, c. February 1817 or 1818 – February 20, 1895) was an American social reformer, abolitionist, orator, writer, and statesman. After escaping from slavery in Maryland, he became a national leader of the abolitionist movement in Massachusetts and New York, becoming famous for his oratory and incisive antislavery writings. Accordingly, he was described by abolitionists in his time as a living counterexample to slaveholders’ arguments that slaves lacked the intellectual capacity to function as independent American citizens. Northerners at the time found it hard to believe that such a great orator had once been a slave. It was in response to this disbelief that Douglass wrote his first autobiography.

The Black Seminoles, or Afro-Seminoles are Native American-Africans associated with the Seminole people in Florida and Oklahoma. They are mostly blood descendants of the Seminole people, free Africans, and escaped slaves, who allied with Seminole groups in Spanish Florida. Many have Seminole lineage, but due to the stigma of having very dark or brown skin and kinky hair, they all have been categorized as slaves or freedmen. Historically, the Black Seminoles lived mostly in distinct bands near the Native American Seminole. Some were held as slaves, particularly of Seminole leaders, but the Black Seminole had more freedom than did slaves held by whites in the South and by other Native American tribes, including the right to bear arms.

Gabriel (c. 1776 – October 10, 1800), referred to by some as Gabriel Prosser, the surname of his slaveholder, was a man of African descent born into slavery in 1776 at Brookfield, a large tobacco plantation in Henrico County, Virginia. Gabriel was literate. He was one of the rare 5% of enslaved people of the colonial era who were able to learn to read and write.

Gabriel’s Rebellion was a planned slave rebellion in the Richmond, Virginia, area in the summer of 1800. Information regarding the revolt, which came to be known as “Gabriel’s Rebellion”, was leaked prior to its execution, and Gabriel, a blacksmith who planned the event, and twenty-five followers were hanged. The site of Gabriel’s execution was for several years believed to have been at the Shockoe Bottom African Burial Ground, historically known as the Burial Ground for Negroes. His execution was advertised as occurring at the usual place, however in 1800 that may have been a location other than the Burial Ground for Negroes.

Matthew Alexander Henson (August 8, 1866 – March 9, 1955) was an African American explorer who accompanied Robert Peary on seven voyages to the Arctic over a period of nearly 23 years. They spent a total of 18 years on expeditions together. He is best known for his participation in the 1908–1909 expedition that claimed to have reached the geographic North Pole on April 6, 1909. Henson said he was the first of their party to reach the pole.
