This paper is divulging unpublished materials based on recent research on E. M. Jellinek who was the father of the scientific-medical agenda of alcohology. Results of our research in Hungarian archives not only open still unexplored realm for alcohol studies but also evoke fresh readings of its history. A good half of Jellinek's life has been uncharted and still contains terrain unbeknown to us. Following some infamous activity he fled from Hungary on the very same day (June 4, 1920) when the country lost two-thirds of its territory. After a ten-year roaming Jellinek's private Odyssey came to an end. He has started living his personal "American dream" in the country of his mother through the impersonal dream of alcohology, which was going to aspire to transform itself from a moral movement to an emerging interdisciplinary field of medicine. Jellinek had chosen to be uprooted and he managed to conceal his past in Budapest including his trans-generational past quite effectively. Authors have made an attempt to interpret the ambivalent tale and controversial personality of Jellinek embedded in the progress of alcohol studies.
