Singer Building ca. 1908

Architect Ernest Flagg had already designed two buildings for the Singer Manufacturing Company when, in 1906, the company declared it would build the world's tallest building. Flagg achieved the company's goal by utilizing innovative techniques in wind bracing and the anchoring of the building's steel frame, which allowed it to soar to a height of 612 feet. Completed in 1908, the ornate Beaux-Arts tower, with its distinctive lantern top, stood out in the Manhattan skyline and served as a billboard for the Singer Company. For 50 cents, visitors could ascend to the 40th-floor observation deck. In accordance with newly enacted zoning laws, the slender tower was set back from the street and occupied only one-fourth the area of the building from which it arose. The success of the design influenced the use of setbacks, which became a standard feature of successive skyscrapers.

In 1968, the Singer Tower became the tallest building ever demolished when its new owner, U.S. Steel, sacrificed it for the glass and steel One Liberty Plaza.
