Numerous schools are named for Sandburg throughout the United States, and he was present at some of these schools' dedications. (Some years after attending the 1954 dedication of Carl Sandburg High School in Orland Park, Illinois, Sandburg returned for an unannounced visit; the school's principal at first mistook him for a hobo.) Sandburg Halls, a student residence hall at the University of Wisconsin–Milwaukee, carries a plaque commemorating Sandburg's roles as an organizer for the Social Democratic Party and as personal secretary to Emil Seidel, Milwaukee's first Socialist mayor.
