What If … Public Health Had to Be Built From Scratch? Revisiting 19th-Century Debates
Join us on Wednesday, February 25th for the Department of Epidemiology seminar series featuring Dr. Alfredo Morabia discussing What If … Public Health Had to Be Built From Scratch? Revisiting 19th-Century Debates.
Abstract: What would public health look like if it had to be invented today, without assuming the institutions, divisions, and categories we inherited? This lecture revisits the formative debates of the 19th century, when scientific public health first took shape. By examining the tensions between competing visions, particularly between approaches centered on specific causes of disease and those focused on the broader conditions of life, I show that public health emerged not as a single, inevitable model but as the outcome of choices. Situating epidemiology and the early schools of public health within these debates, I argue that some options were abandoned rather than disproven. Revisiting these debates allows us to think more clearly about what public health could be today, not by returning to the past, but by recovering the range of possibilities that once existed.
