John Pierre Burr

John Pierre Burr (June 1792 – April 4, 1864) was an American abolitionist and community leader in Philadelphia, Pennsylvania, active in education and civil rights for African Americans. He was an illegitimate child of Aaron Burr, the third U.S. vice president, and Mary Emmons, a Haitian governess who may have been born in Calcutta, India.

According to the Philadelphia Preservation Alliance, the Burr house was at Fifth and Spruce Streets, in the Society Hill area of the city. The documents were shared with the Aaron Burr Association and historical societies, to ensure their preservation.

In 2018, Burr and his sister Louisa were formally acknowledged by the Aaron Burr Association as the children of Aaron Burr after a DNA test showed a familial link between descendants of John Pierre and Aaron Burr. In 2019, a new headstone was unveiled in Eden Cemetery, identifying John Pierre Burr as a "Champion of justice and freedom, conductor on the Underground railroad".
