Formerly owned by the nephew of Colonel McCormick of the Chicago Tribune, Chauncey McCormick. More info here.
In 1920, Chauncey and Marion McCormick purchased St. James Farm as a private retreat to accommodate their interests in horses and dairy farming. The McCormicks’ son, Brooks, later transformed St. James Farm into a renowned equestrian facility. Brooks McCormick sold St. James Farm as a life estate to the Forest Preserve District of DuPage County in 2000. The Forest Preserve District officially took possession of the 607-acre property in 2007.
