ABSTRACT
The study of race relations between whites and African Americans was of primary interest to the men and women of the Chicago school of race relations (CSRR) and the Hull-House school of race relations (HHSRR). The men of the early Chicago school of sociology (CSS) were on the forefront of patriotic expertise during World War I (WWI), especially after America entered the war in 1917. MacLean was a patriotic Canadian who supported the Allied war effort, siding with the men of the CSS and not the women of the Hull-House school of sociology (HHSS) on this issue. MacLean's public sociology reached a wide and receptive audience and captured the public imagination. MacLean concentrated on immigrant groups from the British Empire and South America, in contrast to the male Chicago sociologists who primarily studied Eastern Europeans. MacLean's study of immigration had both public and private dimensions.
