RESUMO
The cover of this issue of Technology and Culture illustrates how China implemented-and promoted-on-the-job training in Africa. The image shows a Tanzanian dentist practicing dentistry under the supervision of a Chinese doctor in rural Tanzania, probably in the 1970s. Despite the ineffectiveness of the on-the-job training model, the photograph attempts to project the success of the dental surgery techniques exchanged between China and Tanzania, using simple medical equipment rather than sophisticated medical knowledge. The rural setting reflects the ideological struggle of the Cold War era, when Chinese doctors and rural mobile clinics sought to save lives in the countryside, while doctors from other countries engaged in Cold War competition worked primarily in cities. This essay argues that images were essential propaganda tools during the Cold War and urges historians of technology to use images critically by considering the contexts that influenced their creation.
