I trace an account of social workand sociologythat I believe holds a promise for re-forming the relationship between the two. I develop the argument in two ways. First, taking 1920s Chicago as a case study, I will attempt a history of the present' to suggest how the relationship between sociology and social work came to be as it is. I will suggest that the practice of some (both familiar and forgotten) people in 1920s and 1930s sociology and social work is best explained as a form of sociological social work'. Second, after tracking this genealogy, I suggest an agenda for sociological social work that consists of straining to enact certain kinds of inter-disciplinary relationships, developing methodological social work practice, hearing occasional sociological frontier conversations and shared theorising. I illustrate how these arguments challenge both sociology and social work and both theory and practice. Jeg eftersporer udviklingen af socialt arbejdeog sociologida jeg tror, at dette kan medvirke til at gendanne forholdet mellem de to omrader. Jeg udvikler argumenterne pa to mader. FOrst tager jeg 1920'ernes Chicago som et casestudie, hvor jeg med en history of the present'tilgang undersOger, hvordan forholdet mellem sociologi og socialt arbejde udviklede sig, som det gjorde. Jeg foreslar, at (bade velkendt og glemt) praksis blandt personer i 1920'erne og 1930'ernes sociologi og socialt arbejde bedst kan forklares som en form for sociologisk socialt arbejde. For det andet, efter at have eftersporet denne genealogi, foreslar jeg en dagsorden for sociologisk socialt arbejde, der bestar af bestraebelser pa tvaerfaglige relationer; at udvikle metoder i det sociale arbejdes praksis; at lytte til de sociologiske graenseomrader; og at dele teoretisering. Jeg illustrerer, hvordan disse argumenter udfordrer bade sociologi og socialt arbejde, bade teori og praksis.
