Eradicating syphilis? Alternative projects, failures, and infectious disease control in the French colonial empire...

The inter-war period was a time of mobilisation against syphilis in France and its colonial empire. The spread of the disease was perceived as a threat to the economic development of its colonies, particularly because of the labour shortages it might cause. In 1916, a new player appeared on the scene of the French efforts to control the disease: the Institut Prophylactique, founded by Arthur Vernes. Its project was nothing less than to eradicate the disease, and its activities in the colonies expanded significantly during the 1920s and 1930s. However, the Institut Prophylactique has been largely forgotten in the history of medicine. Although the project was a failure, this article shows that it played an important role in controlling syphilis, both in France and in its colonies. This historical study thus emphasises the importance of considering alternative and failed projects as part of the complex picture of health history.
