Over a period of half a century, from the 1940s to the 1990s, Edmundo O'Gorman came to occupy a unique place in Mexican historiography. Though he might be considered as quasi-aristocratic in his thought and in his bearing, he spent his entire career as teacher and scholar at the popular Universidad Nacional Autónoma de México (UNAM), not at the more elitist El Colegio de México. Unlike Daniel Cosío Villegas, with whom he is often paired as the leading Mexican historians of their generation, he was not politically engaged, nor was he a ‘cultural caudillo’; he appeared to shun the attractions of academic administration and power. He was, however, an avid intellectual organiser and provocateur, who relished debate and welcomed polemical interchanges with colleagues at home and abroad.
