Abstract

British biologist and science populariser J. B. S. Haldane was known as a contrarian, whose myriad ideas and beliefs would shift to oppose whomever he chose to argue with. Yet Haldane's support for synthetic food remained remarkably stable throughout his life. This article argues that Haldane's engagement with synthetic food during the 1930s and 1940s was shaped by his frustration with the status and direction of scientific research in Britain. Drawing upon the Haldane Papers, I reconstruct how Haldane's interest in synthetic food emerged from the biochemical and physiological optimism of the early 20th century. His mid-20th-century writings were an opportunity for Haldane to voice his political opinions. He attempted to erase the conceptual divide between farm and factory, maintained that food shortages were a capitalist construct, and criticised British colonialism. By pointing out the failure of existing economic systems and governments to develop synthetic food, Haldane made the case that food production should be placed under the control of biologists.
