 Millard F. Singleton, John Albert Williams, E. H. Hall, Walker and others were important leaders in those efforts.Tom Dennison arrived in Omaha in the 1880s and set about creating a criminal and political alliance which would come to influence Omaha politics until his death in 1934.Walker's connections with the African-American community, with houses of gambling and prostitution, and with the legal system were useful to Dennison, and in 1898 Dennison financed Walker's purchase of a salon, "The Midway", at 12th and Capitol Ave, from Oscar Picketts, with whom Dennison had a dispute.
