April 23, 1970 – The Chicago Tribune reports that the Commission on Chicago Historical and Architectural Landmarks has voted unanimously to give landmark status to two Chicago historical sites – the Hull House mansion at 750 South Halsted Street and a block of 40 row houses on Alta Vista Terrace, not far from Wrigley Field. The Hull House mansion was built in 1856 for Charles J. Hull, a Chicago real estate broker but by 1910 had become the center for a 13-building complex that was home to the social settlement community of Jane Addams. The mansion and one other building are the only two structures that remained after the University of Illinois began levelling the area for the building of its Chicago campus. The Alta Vista terrace area is only the second such district to be designated as a landmark, the first being the area surrounding the Chicago water tower on Michigan Avenue. Hearings within the month will determine the status of the Leiter I building at 208 West Monroe Street and the Monadnock Building at 55 West Jackson Boulevard. Leiter I will not make the cut and will be demolished in 1972. The Monadnock, fortunately, will receive landmark status and will be meticulously restored.
