Daniela Gleizer is an associate researcher at the Instituto de Investigaciones Históricas at the Universidad Nacional Autónoma de México (UNAM) focusing on the relationship between the Mexican state and foreigners, particularly on immigration and naturalization policies. Gleizer earned her Ph.D. in History from El Colegio de México, in Mexico City and has received various awards for her work, among them the national prize for the best undergraduate thesis in history, the Rabbi Jacobo Goldberg prize for best Ph.D. Dissertation (on Jews in Mexico), an honorable mention from the LAJSA Book Award for Unwelcome Exiles and the prize of the Mexican Committee for Historical Sciences for the best article published in 2015 in the category of political history (for Gilberto Bosques and the Mexican Consulate in Marseille). Her principal book, which looks at the subject of the Mexican stance towards Jewish refugees during Nazism, questions the country’s “open door” myth by pointing to the limitations placed by the Mexican immigration policy on a number of nationalities, religious and political groups, including the Jews. In this respect her work has been important in demonstrating the link between public policy and the ideology of mestizaje (miscegenation), which postulated the notion that certain groups were “capable of assimilation” into the Mexican “racial mix” while others were not. She has also worked on the relationship between Mexico and the Third Reich, and the role of the consuls in granting visas during the Second World War. Gleizer is currently working on two projects: one on the limits of citizenship policy in Mexico and the other on the witness accounts of Holocaust survivors who arrived in Mexico.
