The impact of Salo Wittmayer Baron on the study of the history of the Jews during the Middle Ages has been enormous. This impact has, in part, been generated by Baron's voluminous writings, in particular his threevolume The Jewish Community and–even more so–his eighteen-volume Social and Religious History of the Jews. Equally decisive has been Baron's influence through his students and his students' students. Almost all researchers here in North America currently engaged in studying aspects of medieval Jewish history can surely trace their intellectual roots back to Salo Wittmayer Baron. In a real sense, many of Baron's views have become widey assumed starting points for the field, ideas which need not be proven or irgued but are simply accepted as givens. Over the next decade or decades, hese views will be carefully identified and reevaluated. At some point, a major study of Baron's legacy, including his influence on the study of medieval Jewish history, will of necessity eventuate. Such a study will have, on the one hand, its inherent intellectual fascination; at the same time, it will constitute an essential element in the next stages of the growth of the field, as it inevitably begins to make its way beyond Baron and his twentieth-century ambience.
