Standard Oil Building, 1926.

The Standard Oil Trust, founded in 1870 by John D. Rockefeller and others, quickly came to dominate the American oil market. In 1883, the trust began acquiring land on lower Broadway for a new headquarters. The massive nine-story neoclassical granite building took two years to construct at a cost of one million dollars. Twenty-six Broadway was soon the world's most famous business address, and John D. Rockefeller the first billionaire.

Six stories were added to the building in 1895, as shown here. Another floor, added in 1911, was barely complete when the U.S. Supreme Court disbanded the Standard Oil Company for violating anti-trust laws.

Following the First World War, the surrounding buildings were bought in order to expand the structure. Thomas Hastings of Carrère and Hastings reworked and essentially rebuilt the entire building, incorporating the first set backs in Manhattan and a pyramidal structure. Eventually reaching 31 floors, the Standard Oil Building was designated a New York City landmark in 1995.
