Hans Knöpfli was the last missionary sent out by the Basel Mission. He arrived in Cameroon in 1956, a year before the Presbyterian Church in Cameroon (PCC) was constituted as an independent church, a development that also seemed to herald Cameroon’s independence in 1961. During his first years there, Hans Knöpfli and his camera witnessed the PCC’s participation in the founding of the Federal Republic of Cameroon–a political move that was diametrically opposed to traditional and state power in the Grasslands. In my analysis of the images, I explore the question of whether his images of this significant day reflect what Marianne Gullestad, in a postcolonial analysis of mission photography, called “asymmetrical colonial relations that determine the terms of authorship and ownership,” or whether they support the argument make in my dissertation, in which I argue that mission photography in its complexity needs to be included in a broader debate about the role of photographic images in order to understand the historical ambivalence and juxtaposition, which occurred in the onset of the decolonial period in the grasslands of Cameroon.
