Abstract

In Mexico, the absence of significant foundational moments and heroic characters in the development of chemistry in the first quarter of the twentieth century has caused this period to pass almost unnoticed in the historiography of chemistry in Mexico. However, an approximation of some individuals, mostly pharmacists, who have been scarcely studied and considered secondary allowed us to identify and analyze the spaces where chemistry was produced, taught, practiced and professionalized. Our purpose is to present how and where chemistry developed during this period and the main social actors involved in this process.
