On September 20, 1932, high above 41st Street in Manhattan, 11 ironworkers took part in a daring publicity stunt. The men were accustomed to walking along the girders of the RCA building (now called the GE building) they were constructing in Rockefeller Center. On this particular day, though, they humored a photographer, who was drumming up excitement about the project’s near completion. Some of the tradesmen tossed a football; a few pretended to nap. But, most famously, all 11 ate lunch on a steel beam, their feet dangling 850 feet above the city’s streets.

The guy on the extreme left of the picture with the cigarette is Mattie Shaughnessy. He was born in Rinrush, near Kiltartan, went to school in Kiltartan N.S now the Kiltartan Gregory Museum. His name can be found in the 1912 Roll Book which can be seen in the museum.
