Philip Reed, known as Philip Reid before he was emancipated, was an African American master craftsman who worked at the foundries of self-taught sculptor Clark Mills. There, historical monuments such as the 1853 equestrian statue of Andrew Jackson in Lafayette Square, near the White House in Washington, D.C., the 1860 equestrian statue of George Washington in Washington Circle, and the 1863 Statue of Freedom in Washington, D.C., were created.

Columbian Harmony Cemetery was an African-American cemetery that formerly existed at 9th Street NE and Rhode Island Avenue NE in Washington, D.C., in the United States. Constructed in 1859, it was the successor to the smaller Harmoneon Cemetery in downtown Washington. All graves in the cemetery were moved to National Harmony Memorial Park in Landover, Maryland, in 1959. The cemetery site was sold to developers, and a portion used for the Rhode Island Avenue – Brentwood Washington Metro station.
