opened in September 1929 in a building similar to the Evanston store. Frederick & Nelson, a Seattle, Washington-based department store founded in 1890, was also acquired in 1929, with its own 1914 downtown Seattle building at Pine Street and Fifth Avenue. Frederick & Nelson retained its name, though its logo was soon rewritten in Field's iconic script. Frederick & Nelson created Frango mints, a Seattle tradition then and now. The mints were later also produced in the candy kitchen in the State Street store and became popular in Chicago, too. Marshall Field & Company became a public company in 1930, early in the "Great Depression". The retailer needed capital due to the expense of opening the massive new Merchandise Mart to house its flagging wholesale division. Ground was broken in 1927 during the boom years of the "Roaring 20s"; when the Mart opened in 1930, it was the largest building in the world. The 1887 Wholesale Store designed by Richardson at Franklin between Quincy and Adams Streets was closed and demolished at this time. But the new building, faced with a change in retail distribution and wholesale patterns in addition to the deepening "Great Depression", could not save Field's wholesale division. Simpson left the Company, and James O. McKinsey, a University of Chicago professor and founder of the McKinsey and Company consulting firm, was hired to reform the Company. The wholesale division, once the core of the Company, was liquidated by 1936. The Davis Store was closed in 1936 as well, and its building was sold to Goldblatts. In 1939, the land underlying the main State Street store was acquired from the Marshall Field Trust. Meanwhile, McKinsey also reorganized the Company's vertically integrated operations, notably by merging the Company's varied textile operations under the Fieldcrest name. Suburban expansion Following World War II, the Merchandise Mart building was sold in 1945 to Joseph P. Kennedy, Sr., (1888–1969), significantly improving the Field Company's finances and enabling the store to cope with the post-war suburban residential and commercial boom. Marshall Field's presciently followed its customers to their new homes outwards to the suburbs, including opening a store in 1950 in partnership with pioneering suburban developer Philip M. Klutznick (a famous Jewish leader and later U.S. Secretary of Commerce) at his new Park Forest Plaza, which utilized revolutionary new concepts in land use and architecture. In 1956, Klutznick and Field's jointly opened Old Orchard
