Empire State Building
Opening and early years

The Empire State Building officially opened on May 1, 1931, forty-five days ahead of its projected opening date, and eighteen months from the start of construction. The opening was marked with an event featuring United States President Herbert Hoover, who turned on the building's lights with the ceremonial button push from Washington, D.C. Over 350 guests attended the opening ceremony, and following luncheon, at the 86th floor including Jimmy Walker, Governor Franklin D. Roosevelt, and Al Smith. An account from that day stated that the view from the luncheon was obscured by a fog, with other landmarks such as the Statue of Liberty being "lost in the mist" enveloping New York City. The Empire State Building officially opened the next day. Advertisements for the building's observatories were placed in local newspapers, while nearby hotels also capitalized on the events by releasing advertisements that lauded their proximity to the newly opened building.

According to The New York Times, builders and real estate speculators predicted that the 1,250-foot-tall (380 m) Empire State Building would be the world's tallest building "for many years", thus ending the great New York City skyscraper rivalry. At the time, most engineers agreed that it would be difficult to build a building taller than 1,200 feet (370 m), even with the hardy Manhattan bedrock as a foundation. Technically, it was believed possible to build a tower of up to 2,000 feet (610 m), but it was deemed uneconomical to do so, especially during the Great Depression. As the tallest building in the world, at that time, and the first one to exceed 100 floors, the Empire State Building became an icon of the city and, ultimately, of the nation.

In 1932, the Fifth Avenue Association gave the building its 1931 "gold medal" for architectural excellence, signifying that the Empire State had been the best-designed building on Fifth Avenue to open in 1931. A year later, on March 2, 1933, the movie King Kong was released. The movie, which depicted a large stop motion ape named Kong climbing the Empire State Building, made the still-new building into a cinematic icon.
