Since 1947, Wilson Candy has made chocolates and candies at its Jeannette, Pennsylvania factory, where its team still hand-dips confections using recipes passed down through more than three generations. Founded by siblings Paul and Margaret Wilson, the company is known for preserving its original recipes and techniques, including the signature Wunder Bar introduced in 1954. Its longstanding Harrison Avenue manufacturing site also serves as the home of its Jeannette retail store.
