On September 9, 2006, Macy's retired the Kaufmann's name as Federated Department Stores converted the former May Company brands to its masthead.

[2] In 2015, Macy's closed and sold the iconic Pittsburgh store for redevelopment as part of the company's ongoing reorganization of its owned properties.

[18] Designed by architect Charles Bickel,[19][20] the Kaufmann's flagship store was built in 1887 at 400 Fifth Avenue in downtown Pittsburgh.

[22] By 1916, the architects Janssen & Abbott designed a larger white terra cotta-sheathed addition that included a large public clock at the corner.

[citation needed] At one point, the building was the largest department store in Pittsburgh with twelve retail floors, and spanning an entire downtown city block.

[24] Kaufman commissioned Frank Lloyd Wright to design his executive offices on the top floor of The Big Store, as well as his country house 'Fallingwater' (1934) at the company's Bear Run retreat in Pennsylvania.

[27] He also commissioned architect Richard Neutra to design the desert Kaufmann House (1946) in Palm Springs, California.

[28] Kaufmann's flagship Big Store had a landmark outdoor clock at Fifth Avenue and Smithfield Street that existed since the building was first constructed.

[37] Following the purchase by Macy's in 2006, USA Today ran an article about the regional chains merging into Macy's which featured memories from Pittsburgh residents about the store and the clock: "As girls in their best dresses and Mary Jane shoes, they rode streetcars downtown to the 11-story Kaufmann's department store here.

Jean Wenner, 81, and her friends grew up on Kaufmann's, meeting under the store's ornate clock, lunching at the Tic Toc restaurant and bringing their own children to the Secret Santa.

[40] Several Kaufmann's holiday traditions continued to prevail after the company was taken over by Macy's, including animated Christmas windows and Santa Land.

[42] The new development, which includes apartments, restaurants and a hotel, was slated to open in late 2017, but was delayed because the building was without a permanent power source.
