This article examines some aspects of the labour involved in generating, recording and transmitting information in eighteenth-century Europe. It centres on the study of a particular occupational group: the men involved in the day-to-day operations of the schemes for the marketing of life-contingent pensions which would develop into modern life insurance, a form of enterprise whose growth was deeply implicated in the emerging “information society”. The bulk of the work these men did was what we would now call clerical work: keeping and processing records and accounts, managing correspondence, preparing reports for publication. It was in the nature of the information regimes within which they worked and the kind of information they were handling, though, that the responsibilities and demands placed on them went beyond those associated with the mechanical function of recording and reproducing. This made for an occupational profile which was relatively fluid, and only gradually came to be distinguishable from other contemporary forms of middle-class employment, in terms of the disciplines peculiar to it and the hazards it incurred. Among the hazards were forms of mental and physical strain that accompanied rapid increases in the volume of data that had to be handled and in the speed of its circulation, as a direct consequence of its character as “information”. While the account focuses on the study of a particular kind of enterprise in a particular place, northwest Germany, it draws on comparative data for officers and staff in analogous forms of commercial and administrative employment in Britain. The article concludes with a consideration of how their occupational profile might fit into an extended account of the historical development of information work.
