Erratum for Alexandra Minna Stern, “Buildings, Boundaries, and Blood: Medicalization and Nation-Building on the US-Mexico Border, 1910–1930,” Hispanic American Historical Review 79, no. 1 (1999): 41–81.

On p. 43, the age of Carmelita Torres is incorrectly listed as 47. Torres was in fact 17 at the time that she led the protest discussed in the essay. The author identified the erratum when reviewing improved digitizations of the source materials used for the article.
