The story of this building is one of incredible speed and resilience. Construction began on March seventeen, 1930, right in the middle of the Great Depression. In a staggering feat of engineering, the framework rose at a rate of four and a half stories every single week. Around 3,400 workers, including many Mohawk ironworkers legendary for their bravery at great heights, completed the entire structure in just one year and 45 days. This Race to the Sky was a fierce competition against the nearby Chrysler Building and the building at forty Wall Street. When it finally opened on May first, 1931, President Herbert Hoover officially turned on the lights by pressing a button all the way from Washington, District of Columbia. Initially, however, the building struggled to find tenants during the economic downturn, leading locals to mockingly call it the Empty State Building until it finally became profitable in the early 1950s.
