Stretching roughly from West 145th to 155th Streets between Edgecombe and Amsterdam Avenues, Sugar Hill was Harlem's most affluent Black neighborhood from the 1920s through the mid-20th century, home at various times to Duke Ellington, Thurgood Marshall, W.E.B. Du Bois, and Langston Hughes. Its name reflected the "sweet life" enjoyed by the Black professional and artistic class who lived there, in contrast to the economic hardship many Black New Yorkers faced elsewhere in the city. The neighborhood's row houses and apartment buildings, including the Roger Morris and Colonial Parkway Apartments, remain a designated historic district.
