The Pittsburgh Survey was part of the survey movement. The movement was characterized in three key documents of self-interpretation: the fi rst, an article by Paul U. Kellogg, Shelby Harrison, and George Palmer in the Proceedings of the Academy of Political Science in 1912; the second, a paper by Kellogg and Neva Deardorff presented to an international social work convention in 1928; and the third, Shelby Harrison’s introductory essay to the catalogue of surveys constructed by Allen Eaton in 1930. Ordinarily, such documents provide the beginning of historical analysis and are critically revised by later historians. However, there has been relatively little written about the surveys and the survey movement since it expired (the exception is the volume edited by Bulmer et al. 1991). So these texts give shape to a kind of dim memory of a movement to promote social reform through sociological research, which, for mysterious reasons, disappeared.
