This volume presents views of American sociology from minority groups and important intellectual movements that did not merge into the mainstream. Coinciding with the centenary of the American Sociological Association, it provides little-known background information to the development of the field. A first section highlights tensions between impartial scientific sociology and scientific social reform. A second section uncovers the experiences of female, African American, and Latino pioneers in the field, as well as a sociologist from a religious minority. A third section traces the organizational history of the field, including gendered, racial, regional, and outsider perspectives. A final section focuses on several neglected trajectories. With this volume, American sociology can be seen in its full context.
