Among the thousands of disillusioned republicans who left Germany after the revolutions of 1848 was a Jew named Isidoro Epstein. He was one of the small number of forty-eighters who chose to migrate to Mexico. There the record of his varied career as statistician, mapmaker, educator, publisher, and journalist illustrates how the skills and talents of a professionally trained foreigner met the needs of Mexico as these needs were perceived and defined by the Mexican elite of the second half of the nineteenth century. His career as outspoken liberal editor of German language newspapers, however, was marred by conflict with a German community that was divided in its interpretation of German nationalism and in its feelings about liberals and Jews. Both aspects of Epstein's life in Mexico, from his immigration in 1851 until his death in 1894, demand attention and prove to be fascinating.
