While the rise of Du Bois within U.S. sociology is often framed as a necessary rewriting of the discipline's history, this piece by William Gorman, "W.E.B. Du Bois and His Work," published in *1950* suggests that many onlookers knew the truth about Du Bois & sociology all along.
"Not only is Du Bois' sociology of the Negro superior to similar works by white authors of that period; there is no single body of American sociology on any subject during that period which, for seriousness, thoroughness and extensiveness, can compare with...[Philadelphia Negro]"
This quote is from "Du Bois as Sociologist" in Gorman's piece, published in 1950 by Marxist publication Fourth International, in a special issue entitled "Marxism and the Negro." Link here: https://www.marxists.org/history/etol/newspape/fi/vol11/no03/v11n03w104-may-jun-1950-fourth-int.pdf
