Convenient Food Mart

William J. Bresler and Walter R. Schaub founded Convenient Food Mart, one of the first and one of the best convenience store chains, in Chicago in 1958. Their idea was to provide customers a supermarket in miniature, which would be located in the customer’s neighborhood and perhaps owned by one of the neighbors. The new store they envisioned would be open seven days a week, from early morning until late at night or 24 hours a day.
