The Story
In the small industrial town of Curwensville, engineer Arnold N. Nawrocki solved a problem that quietly reshaped American kitchens: how to package cheese one slice at a time. Working for the Clearfield Cheese Co. in the mid-1950s, he devised the first commercially successful process for individually wrapping cheese slices, earning a patent in 1956. Over his career he accumulated eleven food-processing patents, marking him as one of the unsung inventors of the postwar convenience-food era.
Why it matters
His invention became a fixture of the American grocery aisle and lunchbox, a small but telling example of how mid-century Pennsylvania industry helped standardize the way a nation ate.

Leap-The-Dips Roller Coaster
Logan Township, PA · est. 2000
Built in 1902 by Philadelphia's E. Joy Morris, Leap-The-Dips is a side-friction figure-eight coaster from the dawn of the American amusement-park era, when hundreds of such wooden rides thrilled crowds at trolley parks nationwide. As tastes changed and the others were torn down, this one at Lakemont Park endured to become the last of its kind and the world's oldest known operating roller coaster. It carries National Historic Landmark status.
Canal Basin
Hollidaysburg, PA · est. 1982
At Hollidaysburg, the 127-mile Juniata Division of the Pennsylvania Canal met the Allegheny Portage Railroad, an ingenious system that hauled canal boats over the mountains toward Johnstown, 36 miles west. The canal opened in 1832 and the railroad in 1834, together forming a continuous route across the formidable Allegheny barrier. Engineers marveled at the portage line, which climbed nearly 1,400 feet in just ten miles using inclined planes.
Rural Electrification
White Township, PA · est. 1988
In 1936, three of every four Pennsylvania farms still went dark at sundown, cut off from the electric grid that already lit the cities. Federal support during the New Deal changed that, spurring farmers to band together into consumer-owned cooperatives. One of them, the Southwest Central Rural Electric Cooperative, was incorporated here in 1937 to bring power to users across seven counties.
