Based on the address, I think these homes were located under what is now Truman College, just south of Wilson.
According to Wikipedia: Amundsen High School hosted a night school offering two-year college programming for the North Side of Chicago in 1956. This was the result of community outcry for a two-year college for the economically ailing community areas north of downtown Chicago. Interested in a more permanent situation for the program, community leaders acquired a former elementary school campus in 1961 and enrolled 4,000 students in day and night classes. Further growth led to the construction of its present campus on West Wilson Avenue, opening its doors in 1976, naming the school after U.S. President Truman.
Fun Fact: Truman College was featured in the 2002 movie My Big Fat Greek Wedding written by and starring Nia Vardalos.
