“A Shared Toxic History,” in History Unclassified, American Historical Review 125, no. 5 (December 2020).

This essay is about the search for answers in family histories of illness, a search that may never end. It also explores how toxic exposure connects people—mothers and daughters, teachers and students—in unexpected ways. In the history classroom, the author finds new insights about environmental health in the shared experiences of course text authors, students, and families.
