The J. C. Penney House in Kemmerer, Wyoming, was the home of James Cash Penney, the founder of the J. C. Penney department stores, during the 1904-1909 period that he developed his formula for a successful dry goods store. Penney and wife moved to Kemmerer in 1902 and lived in the garret of a small house. With a child, it was too small, and Penney bought this two-storey house in 1904. It was small, too: about 25 feet (7.6 m) wide and sloping down to the back, going about 30 feet (9.1 m) deep.[2]
During this period he was operating the "mother store" of the future J.C. Penney empire.[3]
It is now operated as a house museum at least during the summer.
