Prospect Hill Cemetery was added to the Register of Historic Places of the District of Columbia (a listing of historic sites maintained by the city) in 2005. Edward F. Abner was the nephew of Edward Abner, one of the most prominent beer brewer's in the District of Columbia in the mid 1800s. Edward F. Abner followed in his uncle's footsteps, purchasing the Albert Brewery in the Foggy Bottom neighborhood in 1897.
