Department store
Marshall Field & Company originated in 1852. It was the premier department store on the main shopping street in the Midwest, State Street in Chicago. Upscale shoppers came by train from throughout the region, patronizing nearby hotels. It grew to become a major chain before converting to the Macy's nameplate on 9 September 2006. Marshall Field's served as a model for other department stores in that it had exceptional customer service. Field's also brought with it the now famous Frango mints brand that became so closely identified with Marshall Field's and Chicago from the now defunct Frederick & Nelson Department store. Marshall Field's also had the firsts; among many innovations by Marshall Field's were the first European buying office, which was located in Manchester, England, and the first bridal registry. The company was the first to introduce the concept of the personal shopper, and that service was provided without charge in every Field's store, until the chain's last days under the Marshall Field's name. It was the first store to offer revolving credit and the first department store to use escalators. Marshall Field's book department in the State Street store was legendary; it pioneered the concept of the "book signing". Moreover, every year at Christmas, Marshall Field's downtown store windows were filled with animated displays as part of the downtown shopping district display; the "theme" window displays became famous for their ingenuity and beauty, and visiting the Marshall Field's windows at Christmas became a tradition for Chicagoans and visitors alike, as popular a local practice as visiting the Walnut Room with its equally famous Christmas tree or meeting "under the clock" on State Street.
Frederick &amp; Nelson
At the age of 69 in 1929, D. E. Frederick decided to retire and he sold the store to the Marshall Field Company for $6 million. He was most impressed with the policies of Marshall Field and had even patterned Frederick & Nelson after Marshall Field and Company. They signed a 99-year lease that would pay Frederick (and later his estate) $100,000 a year.
In 1943, Frederick & Nelson opened a satellite store at Boeing Field at the Boeing Airplane Company’s Number 2 Plant. They supported the war effort and built a loyalty among the airplane manufacturer’s 47,000 employees. Frederick’s also established a "Victory Post" on the main floor of the Seattle store, selling War Bonds and stamps. Frederick’s was one of a handful of stores in the nation to receive a U.S. Treasury Department T-Flag. The T-Flag signified that more than 90 percent of the employees invested at least 10 percent of their earnings in War Bonds. 
D. E. Frederick’s dreams for expansion of the original store at Pine Street and Fifth Avenue finally were realized when the grand re-opening was celebrated August 4, 1952. There were ten floors above ground and two below. The building housed a beauty salon, post office, moving picture auditorium, a fully equipped medical facility, and a nursery. There were reading and writing rooms, and the large, elaborately furnished fifth-floor tea room could seat 400. On the tenth floor the company built a modern candy kitchen that could turn out more than 500,000 pounds of Frango chocolates a year. Later the company added a kindergarten and a children's barbershop. (The original Frederick & Nelson store reopened as Nordstrom’s flagship store in 1998.)
