A look back at the nation’s industrial past comes to life in Bethlehem, where the National Museum of Industrial History shares stories built on the former Bethlehem Steel site.

The museum preserves the history forged here and across the country, displaying more than two hundred artifacts, including pieces on loan from the Smithsonian. One of the first exhibits pays tribute to the 1876 exposition in Philadelphia, the first world’s fair in the United States and the first to showcase a machinery hall.

Docent Larry Lang guides visitors through generations of innovation, from steel and iron to textiles and propane. Interactive displays show how machines and workers shaped daily life, including a steam engine from Switzerland paired with American‑made compressors that once helped create early refrigeration.

New Jersey’s role also stands out. Three silk‑making machines were built in Paterson, known as Silk City, and later used in Hawthorne.

The museum’s newly built second floor doubles as an event space and highlights broader parts of America’s industrial story, from printing to weaving. Lang says the goal is to help visitors appreciate the work of earlier generations and understand how their contributions shaped the world today.
