Structural Steel Trivia: Lunch Atop a Skyscraper

The famous black-and-white photo, “Lunch Atop a Skyscraper,” was taken in 1932 at the construction site of the steel-framed RCA Building (renamed the GE Building in 1986) at Rockefeller Center in New York City. The photo shows 11 ironworkers eating lunch, seated on a crossbeam with their feet dangling about 850 ft above the streets of the city. It was taken on the 69th floor of the building toward the end of construction. (Photo: Wikipedia Commons)
