Richard Pankhurst and Denis Gerard are well known to Ethiopians and those interested in Ethiopia. One of the many publications in their names, is "Ethiopia Photographed: Historic Photographs of the Country and its People Taken between 1967 and 1935" (1996). The book has a brief historical introduction, and it followed by hundreds of photographs spread over 168 pages, each with short descriptions.
The book has six sections: (1) Historic Personalities: From Tewodros to Haile Sellassie, (2) Historic Towns: North, South, East and West, (3) Addis Ababa: the "New Flower", (4) Economic, Social and Cultural Life: Tradition and Diversity, (5) Innovation and Modernization, and (6) Preparing to Resist the Impending Invasion.
For those who have spent time reading about Ethiopian history, this book provides imagery to color the narratives. Photographs have their own biases; who takes them, who gets photographed, which areas are represented and which are not, and so forth. Given these limitation, the book is an excellent and unique collection.
