"A visitation of providence:" Public health and eugenic reform in the wake of the Halifax disaster.

The Halifax Explosion provided the opportunity for an "experiment in public health" that was meant not only to restore but also to improve the city and its population in the process. The restructuring that occurred during the restoration was influenced by pre-existing ideals and prejudices which were reflected in the goals of the newly formed committees in charge of the reconstruction. The primary emphasis on improvement as well as control was the result of existing regional concerns regarding the emigration of the province's most "desirable" stock, in the form of healthy, educated young men and women, to central Canada and the eastern United States. Public health reforms reflected the eugenic goal of improving the overall quality of the population through education, surveillance, and inspection, resorting finally to institutionalizing people who public health officials determined were genuinely deficient.
