This is an annual collection of studies of individuals who have made major contributions to the development of geography and geographical thought.This twenty-seventh volume of "Geographers: Biobibliographical Studies" brings together essays on leading figures in time geography and regional theory, on GIS, on regional, cultural and political geography, on scriptural geography, historical geography and methodology, and on African exploration. Each essay engages with the individual's contribution to geography, their works and their lives and the intellectual and social contexts in which they worked and which helped shape them. In addition - and to mark the new co-editorial pairing leading the series - the volume has an essay on the history of GBS, on the importance of biographical work in the history of geography and on issues to be addressed by the scholarly communities engaged in promoting this vital area of geographical research.
