The Beginnings of Operational Researchose work is spread, if not over a lifetime, then over a significant number of years. Thus positivist sociology is usually taken to begin with the work of Saint-Simon and Comte in the mid-nineteenth century (Keat and Urry, 1982). A few years earlier than this, van Humboldt and Ritter were laying the
