EMPIRE STATE BUILDING
The Empire Building located at 71 Broadway on the corner of Rector Street in the Financial District of Manhattan, New York City is a 21-story steel framed curtain-wall skyscraper designed by Kimball & Thompson in the Classical Revival style and built by Marc Eidlitz & Son from 1895 to 1898. It is one of the earliest skyscrapers built on pneumatic caissons and one of the oldest still standing today. The building was the home of United States Steel Corporation from its founding in 1901 to 1976. Since 1997, it has served as an apartment building. It was designated a New York City landmark in 1996 and placed on the National Register of Historic Places in 1998. In 1884, Orlando B. Potter purchased a six-story 1859 brownstone office building at 71 Broadway. It was the site of an assassination attempt on Russell Sage in 1891. After Potter died suddenly in 1894, his estate, managed by his children, commissioned the current building. On April 23, 1919, the United States Steel Corporation, a major tenant since its formation in 1901, bought the building from the Potter trust for approximately US$5 million in cash. It was their world headquarters until 1976, even after they sold the building in 1973.
