Rectangular window from a door light made of clear glass, decorated with geometric and floral patterns created with opaque, sandblasted sections. Large semi-circle in middle contains text, Adler & Sullivan, Architects.
This window was designed by Louis Sullivan for the door of his and Dankmar Adler's first office, located in the self-designed Borden Block at Randolph and Dearborn Streets. It was executed by Western Sand Blast Mfg. Co. in 1883. The door was purchased by the Chicago Historical Society from Drehobl Glass Co.
The Chicago architecture firm Adler & Sullivan not only designed some of Chicago's most prominent buildings but played an instrumental role in the development of the pioneering architectural style known as the First Chicago School. Louis Sullivan designed this window in 1883 soon after becoming partners with Dankmar Adler at age twenty-seven. Adler's experience as engineer during the Civil War helped the firm create new foundation and frame designs, allowing them to build some of the first skyscrapers. Sullivan's organic decorative style, seen in this window, was a hallmark of the firm's architectural designs, notably the Auditorium Building and the Chicago Stock Exchange. The two men worked together until 1895, profoundly shaping American architecture.
