In the mid- to late-19th century, the area was home to many of the wealthiest New Yorkers, including members of the Astor, Vanderbilt, and Delano families. Editor and poet William Cullen Bryant, and inventor and entrepreneur Isaac Singer lived in the neighborhood in the 1880s. By the turn of the century, however, warehouses and manufacturing firms moved in, the elite moved to places such as Murray Hill, and the area fell into disrepair. The neighborhood was revitalized beginning in the late 1960s and 1970s.
