The Invention of the ‘Tropical Worker’: Medical Research and the Quest for Central African Labor on the South African Gold Mines, 1903–36

Abstract

In 1903 the South African mining industry began recruiting African labor from Central Africa in order to shore up their labor supplies. From the outset, Central African recruitment was problematic, for Central African mine workers died at very high rates. The primary source of Central African mortality was pneumonia. In response to this high mortality the Union government threatened to close down Central African recruitment, a threat which they carried out in 1913. From 1911 to 1933, the mining industry fought to maintain, and then after 1913 to regain access to Central African labor. Of central importance in this struggle were efforts to develop a vaccine against pneumonia. While the mine medical community failed to produce an effective vaccine against pneumonia, the Chamber of Mines successfully employed the promise of a vaccine eventually to regain access to Central African Labor in 1934. The mines achieved this goal by controlling the terrain of discourse on the health of Central African workers, directing attention away from the unhealthy conditions of mine labor and toward the imagined cultural and biological peculiarities of these workers. In doing so the mines constructed a new social category, ‘tropical workers’ or ‘tropicals’. The paper explores the political, economic and intellectual environment within which this cultural construction was created and employed.
