What is "hess's"

Hess's was a department store chain based in Allentown, Lehigh County, Pennsylvania in the United States. The company started in 1897 with one store, originally known as Hess Brothers, and had grown to nearly 80 stores at its peak in the late 1980s. The chain's stores were eventually closed or sold off in a series of deals in the early to mid-1990s.
