Most of the chapters in this volume emerged out of papers presented there. Patrick Harries, who sadly passed away as we were finalising this volume, inspired and supervised research on the history of science, some of which is presented in chapters by his graduate students in this volume. His guidance was highly appreciated and acknowledged. We thank the Basel Graduate School of History, Basler Afrika Bibliographien, Centre for African Studies Basel, Freiwillige Akademische Gesellschaft Basel and Swiss South African Joint Research Programme for generously funding the workshop, follow-up meetings of the editors and the publication of this book. The editors and authors are extremely thankful to the reviewers for their willingness to review chapters, and for their useful comments which helped to improve the quality of this volume. We wish to record our sincere gratitude to our commissioning editors, Petra Kerckhoff and Sarah Schwarz, and to Jo-Anne Friedlander and Nina Maister for the layout, proofreading and indexing of the volume.
