More than any other political boss of the early twentieth century, Thomas Dennison, the Rogue who ruled Omaha, was a master of the devious. Unlike his contemporaries outside the Midwest, he took no political office and was never convicted of a crime during his thirty-year reign. He was a man who managed saloons but never cared for alcohol; who may have incited the Omaha Race Riot of 1919 but claimed he never harmed a soul; who stood aside while powerful men did his bidding. His power came not from coercion or nobility but from delegation and subterfuge.
