The Wakefern Foo Corp., founded in 1946 and based in Elizabeth, New Jersey (United States), is the largest co-operative group of supermarkets in the United States. The name "Wakefern" is a portmanteau of the founders' names (W for Louis Weiss, A for Al and Sam Aidekman, K for Abe Kesselman, an E added for pronunciation, and FERN for Dave Fern), though the company adopted the name ShopRite for its stores in 1951.
