In the early 1960s, “aluminum mobile school units” – in other words, trailers – were placed on the playgrounds and parking lots of African American schools as a permanent solution to overcrowding. The trailers, ordered by CPS Superintendent Benjamin Willis, were used to maintain de facto segregation in the schools. Sylvia Fischer, a 3rd grade teacher from Shoesmith Elementary and one of the organizers of the 1963 CPS Boycott, told us last year: “A school could be side by side, one would be white and one would be black, one would be comfortable in terms of the number of children in that school, and the other would be overcrowded to the point where sometimes the children were on double shift.”
Bob Lucas, another organizer of the Boycott and leader of Kenwood Oaklawn Community Organization, spoke with us several years ago: “When a black school that was close to a white school became overcrowded, rather than permitting the black kids to cross a block and go to the white schools, the Willis Wagons were put up on the campuses of the black schools in order to contain them.”

One of the key demands of the Boycott was that these trailers be removed. On August 6th, 1963, prior to the Boycott, a protest was organized by community leader and CPS parent Rosie Simpson on a site in Englewood at 73rd and Lowe where a school was being constructed entirely out of Willis Wagons. That’s right; no school, just trailers. We will be posting newly discovered original footage of that protest next week.
The trailers were eventually removed, although there are some reports of a few hanging around the Chicago Public school system as late as the 1990s.
Here’s an article by Paul West about Willis Wagons from the Chicago Tribune on August 3, 1963:
