About the Exhibition

Mohawk ironworkers have shaped the skylines of North American cities for more than 100 years. Using a trade honed across generations, members of the Mohawk nation have traveled great lengths and scaled astonishing heights to build iconic bridges and buildings, earning the nickname “skywalkers.” Their work is intertwined with the modern history of lower Manhattan, where these Native American ironworkers helped build the Twin Towers, aided rescue and recovery operations at Ground Zero, and worked to reconstruct the World Trade Center site.

In 2012 and 2013, New York City–based photographer Melissa Cacciola created tintype portraits of Mohawk members of Local 40, a New York branch of an international ironworkers’ union. A medium dating to the American Civil War era, tintypes are developed directly onto metal plates, producing a unique image. Through her work, Cacciola created a powerful testament to the shared history of the Mohawk ironworkers and the World Trade Center site.

Skywalkers is accompanied by an audio tour, featuring the voices of artist Melissa Cacciola and Mohawk ironworkers Lindsay LeBornge and Jeff Morris. The tour is available in English and in two Mohawk dialects, Ahkwesáhsne and Kahnawá:ke. This is the first time the Museum has translated an audio tour into an indigenous language. The translations are courtesy of the Kanien’keháka Onkwawén:na Raotitióhkwa Language and Cultural Center.
