Urban morphology began to take shape at the end of the nineteenth century as a field of study concerned with the urban landscape. Its origins were largely within central European geography. M.R.G. Conzen was much influenced by pioneers in the field, such as Otto Schlüter, and in the post-war period he authored publications that gave rise to a Conzenian school, first within anglophone geography and eventually more widely. Morphogenetic method, conceptualization of historical development, terminological precision and cartographic representation were characteristic of his work. During the last quarter of the twentieth century this was increasingly recognized as important for an appreciation of the development and significance of the historical grain of urban landscapes. Conzenian thinking has in recent years begun to influence urban landscape management and has been one of the principal stimuli in the origin and growth of an international, inter-disciplinary group of urban morphologists, the International Seminar on Urban Form (ISUF).
