Second Leiter Building: A Chicago Architectural Landmark

The Second Leiter Building, situated at 401 S State St in Chicago, Illinois, stands as a testament to innovative architecture and the city's commercial history. Designed by William Le Baron Jenney and built in 1891, it is celebrated as one of the earliest commercial buildings in the United States to utilize a metal skeleton frame. This construction method allowed for larger windows and open interior spaces, making it ideal for retail use.The eight-story structure occupies an entire block on State Street, between Ida B. Wells Drive and Van Buren Street. Its facade features a grid-like pattern with wide pilasters and simple capitals, showcasing a design that is both functional and aesthetically pleasing. The building's exterior is clad in pink granite, and the large windows provide ample natural light.Originally commissioned by Levi Leiter, the building was first leased to the Siegel, Cooper and Company department store. Later, it became the flagship store of Sears, Roebuck and Company in 1932, remaining a retail hub until 1986. From 1998 to 2020, it housed the Chicago campus of Robert Morris University. The Second Leiter Building was designated a National Historic Landmark in 1976 and a Chicago Landmark in 1997.
