Prohibition Gangsters: The Rise and Fall of a Bad Generation Marc Mappen. New Brunswick, NJ: Rutgers University Press, 2013.Professor Marc Mappen teaches at Rutgers University and has made a reputation as a historian of New Jersey. One of his books is entitled There's More to New Jersey Than the Sopranos (2009). In his latest work, Mappen turns from Tony Soprano to that character's real life progenitors, the gangsters who took advantage of America's experiment with Prohibition to establish illegal empires in its great cities. Mappen argues that the chief criminal beneficiaries of Prohibition form a distinct generation. Most of these men were born between 1880 and 1905. All came from an immigrant background. While the Irish were represented in their ranks, the bulk of the successful Prohibition gangsters were Italian or Jewish, products of the wave of immigration from southern and eastern Europe that reached America around the turn of the twentieth century. Mappen sees the achievements of the Prohibition gangsters as emblematic of a perverse process of Americanization, as these thugs integrated themselves with the wider society, albeit through its dark underbelly.Given its subject matter, a book about the Prohibition gangsters should be a fascinating and exciting read. Mappen does not disappoint. His fast-moving but authoritative narrative takes readers through the Prohibition years and beyond as he traces the careers of such underworld luminaries as John Torrio, Al Capone, Lucky Luciano, Meyer Lansky, Legs Diamond, and Dutch Schultz. To do so, he had to sift through questionable and sometimes contradictory sources. Much of what has been written about American gangsters has been in the form of true books, often produced by authors more interested in sensationalism than in the facts. Typical of the genre is The Last Testament of Lucky Luciano (1975). Purportedly based on Lucky Luciano's own memoirs of his turbulent life, this lurid potboiler was quickly denounced as exaggerated and replete with details that could not be substantiated. For obvious reasons, criminals are not going to leave a scrupulous paper trail on their activities. Certainly, the badly schooled Prohibition gangsters were not a literary bunch. Practically speaking, researching the early history of American organized crime is something like exploring ancient history, where sources are sparse, and good judgment in evaluating them is essential. Mappen does an excellent job of assessing the facts that can be gleaned from contemporary newspaper accounts, police and trial records, and the voluminous popular literature that grew up around the gangsters. …
