Karl Pearson's Grammar of Science, was published with new chapters on statistics in the edition of 1911. With this text, we arrive at the moment of the origins of American statistical sociology before the First World War. The early "inductive sociologists' at Columbia University read the statisticians of the nineteenth century. Both Durkheim and Quetelet were subjects of prewar Columbia dissertations. The FHG Club, — the initials are those of its mentor, Franklin H. Giddings — included the young sociologists who were to become leaders in statistical sociology. One member of this club, F. Stuart Chapin, an early Columbia Ph.D. in sociology, recalled in a memoir of these years that "H. T. Buckle and Karl Pearson were a great inspiration." ¹
